hanalulu126018 wrote Hello everyone Im new to this site and the benz world. I own a 80 450slc and Im having problem with fan blower that keeps blowing the fuse. Is this a ground problem Most likely it is or the fan motor itself could be bad. Ill have to look at the CD to see if it shows where the fan ground is and get back to you. )

I apprciate your input so if the fan blower is dead it would cause the fuse to blow for it. Maybe I will start with checking the voltage at the blower plug.

MERCEDES BENZ SL 107 Am I Screwed Here (Blower Fan)

So weve moved on to fixing the ac on the car now. We believe the blower fan is bad. I called our local NAPA and of course its special order 2k. Called mercedes Wholesale Parts not available unless I get it from Europe 1200. AutohausAZ.com shows a picture with part number if I google it but it wont bring up a price anywhere or list the part under the vehicle. Called no answer left a message. Have I finally found the reason the guy sold the car to us so seemingly cheap .

What exactly is wrong with yours is it the motor or the fan blades Adsit has motors at a good price. mercedes benz Parts & Accessories - mercedes blower Motors - Only

How do you know the blower is bad (there are other reasons that it might not work) If it wont run jiggle the key while you have the blower on defrost to the max and the car running for a few minutes. If it magically starts working its the ignition switch (The electrical part). Its possible to look at the wiring diagram for the plug (which contains a bunch of wire resistors) and power the blower motor

MERCEDES BENZ SL 107 HVAC Fan & Blower Assy

Ive got a beautiful 1989 560SL - its a keeper having spent most of its life in the South and not here in the snowy Midwest. But there are still a few issues with it that I need to get fixed such as the fan and blower Assembly. First I have a relative living in Germany until late summer. I would like to investigate the possibility of having her buy a replacement assembly in Germany then shipping it

I just dont see the logic in spending over 1000 to replace a blower in a car that might be difficult

MERCEDES BENZ SL 107 Is the heatA-C blower fan on an 83 380SL the same as an 81 380SL450SL

I need to replace the blower fan on my 83 380SL. I see several on EBAY that say they fit an 81 380SL or 450SL......but they state that they do NOT fit an 83 380SL. Can anyone tell me if a blower fan for the 81 380 SL will fit an 83 380SL Brian in Austin

As you might imagine I was a bit nervous about drilling

MERCEDES BENZ SL 107 Fuse Issues on 83 380sl - AC Blower & Aux. Fan

Ive had my sl for less than two months and so far have had issues with the air conditioning and the auxiliary fan. When I bought the car the previous owner explained to me that the air conditioning works when turning the key slightly to the left whilst in the ignition. I figured the ignition switch needed to be replaced but after a couple of weeks even that method stopped working and the air conditioning

I would spin both fans by hand to be sure they are not froze up. The aux is easy but the other blower you will have to remove the cover over the firewall. Those two circuits do interact when the AC is on.

My mercedes benz 380SL AC & heater control had similar problems recently. Fill in your profile with vehicle(s) information and location. Makes it easier to assist you.

Melting or blowing a fuse is typically an indication of overload. I think maybe a short is most likely. Also if the blower motor had dry bearings wouldnt they screech like hell (or sieze). If its working then blows fuses it sounds more like a short but who knows with these electrical gremlins. You can take the whole blower motor and fan assembly out and and bench test it. In most cases the fans will

MERCEDES BENZ SL R129 3x30 amp fuses under plastic lid - blower fan aux radiator fans window defogger

Hey all -- my 1992 500SL heater-ac blower fan was working great one day and nothing the next. Ive checked the fuse box under the hood all fuses there are fine. I read someplace that there was a 30amp strip fuse for the heater fan somewhere under the hood but I cant find any such thing. Or could this be the dreaded and expensive blower motor controller module failure Ugh. Any ideas or experiences with this problem Thanks

I found there are 3 30amp strip fuses under that plastic lid - marked as follows - one for the aux radiator fans one for the hardtop rear window defogger and one for the heaterac blower fan. Once I knew where it was no problem. Replaced that (obviously) blown strip fuse and viola the fan worked as it should. The fuse cost me 59 cents. Kudos to Bobterry for the location info. I do wonder why MBZ fused these like they did - how come their not in the normal fusebox under the hood

Quote Originally Posted by Rocco Vespe 1999 SL500 - My heater fan just stopped working. I Checked fuse box - no blown fuses. Can it be something other than just replacing the fan motor Thanks RRV Rocco Check this thread. you can test the wires from the connector at the aux fuse box. If there is power going through there...there is nothing left but your regulator and or blower. If there isnt any power then you start working your way back to your climate control. httpwww.benzworld.orgforumsr129...nter-side.html

There is a strip fuse for the blower motor have you check that one httpwww.benzworld.orgforumsr129...mlpost1815946

MERCEDES BENZ SL 107 Blower fan seal

I have just removed the blower fan to replace burnt out motor and found some rust in one corner around fixing bolt under the rubber seal.My question is how do you remove the seal i fear if i just pull it will tear and if it is so difficult to remove how do you get it back in Any information would be appreciated Thanks Robert

Quote Originally Posted by yka Thank you Rufus.1948 this is very good info. I was afraid to start the new sealing job now I will follow your trick. At the same time I will balance my fan I followed the Glueck Auf excellent blower instructions but somehow I succed to unbalance my fan. At the max speed my fan has a obvious vibration. I try to find better fan weight locations using an adjustable power

Quote Originally Posted by GlueckAuf Sorry youre having bad vibes bud. Cant remember if youre using a new or old motor but I believe Id remove the fans and check for radial play in the shaft see if the shaft might be bent and then test run the motor alone to ensure its not the source of the vibrations. While the bare firmly-secured motor is spinning at high speed touch a steel blade to each shaft starting

MERCEDES BENZ SL 107 Heater blower fan not working

2nd issue (theyll be more) on my newly acquired SL. The rotary dial doesnt activate the fan. It seems to turn without any friction. Thinking I need to remove the fascia and investigate. Is there anything to be aware of john

Thats the mechanical system much easier to work on and the most reliable. Under the bonnet in the back is a cover for the blower motor 6 or 8 screws. You will also find a square elec resistor block for the fan. Test there for power you can remove the blower motor and there are only 2 wires going directly to it. Run power to those to bench test.

My fan speed switch was kaput on one setting only but I replaced it anyway.(expensive) I would check whether the blower motor works first by bypassing all the controls. It will run on high speed only but if it runs that removes the blower as a problem. Checking

MERCEDES BENZ SL 107 blower fan removel

Guys I have a 1985 380sl and i decide to check the blower motor out. this car has sat for 5 years and i was worryed about a mouse house under that black cover. to my suprise no mouse house and no rust BUT I whant to pull the motor and after looking at the motor mt bolts they looked rustey so i sparyed them with pb blaster a couppel days ago. anyway i tryed to take the nuts of the studs and it moved

Unfortunately theres nothing to grab onto on the other side of those studs. They have a thin round head thats welded to the underside of the blower box frame. As strife2 wisely says take your time and soak em good and long. Id add to that to when loosening seems to stall (and I mean with VERY moderate torque) stop reverse your ratchet and go the opposite direction for a few degrees soak well again

Ugh. I hope Im not into that soon. My blower fan has stopped working - worked fine until last week then suddenly didnt when I took it out later in the week. The compressor definitely works - I get a little cool air through the vents while traveling - just no fan. I can also see the clutch engage when the on-off compressor switch is turned on and the engine speed adjusts appropriately. Because the compressor

Thanks Scott. Ill try that first. I did buff fuse 6 (and Ill do it again) but not the others. All the fuses involved are copper but it corrodes too. 6-13-2011 update -- Im adding the final resolution here to avoid taking this thread further off course. On Scotts recommendation I pulled all of the top row fuses to clean the brass mounts and to check the fuses for corrosion. Lo and behold when I got

MERCEDES BENZ SL 107 Blower Fan on

Well since you were so helpful on the stumbling issue here goes another one Does the 107 1973 450SLC have an auto feature with regards to the blower Motor I live in the So Cal Desert and it averages above 105 degrees from May through about now (September) when it is hot my blower Motor comes on at full blast when I start the car with no control inputs. Nor will turning the blower motor off with the

Had the same problem thought it was a intermittent short but it was very simple. The fan speed is selected by several resistors located in a square box with lots of holes on RHS front of blower assembly. A bi-metallic high temperature switch protects the resistors by shorting them out. The gap of this switch may become too small over time and I fixed it by carefully pushing a flat screwdriver in the gap and increasing it.

me but working on this old car is new to me. Do I need to pull the blower motor assembly out of its little world under the hood then actually pull the electric motor out of that plastic case Sorry to ask but you may need to be a little more detailed. I know how to arrest and book people and let some go. Everything else is rocket science Might be a good idea to spend time around a reputable benz

MERCEDES BENZ SL 107 83 380SL Blower Fan for heatAC is Tight and doesnt want to trun

The blower fan on my recently acquired 83 380SL is tight. I pulled the assembly out and it would barely turn. I then removed the dual squirrel cage and motor assembly from its black plastic case......and soaked the bushings (or bearings) with a penetrating lubricant then forcefully rotated it back and forth repeatedly. It did eventually loosen a bit but its still very tight......nowhere close to being able to spin. Has anyone experienced this Is there a fix for it Brian in Austin

MERCEDES BENZ SL 107 Blower Fan roars on low speed ...

The heater blower fan in my 1986 560SL roars sometimes on low speed but sounds fine at high speed. Do you think its something loose needs lubrication out of balance Carl

I hope its as simple as adjusting the motors fan blades and tightening it down. It sure is a likely supposition as sometimes on low speed it is quiet other times it roars. Not easy bending over the engine and I cant see down inside well with the cover off. BTW can the hood be turned straight up 90 degrees like I have seen in some videos of other mercedes Carl

Nothing needs to be removed. And definitely only one side. It should be in the owners manual but I dont see it in my 72 manual. I should remember because I had my hood up that way on 300D all summer while working on car ADDED Looks like different models have different set-ups. And it seems that 107s dont have the hinge release that many other MB models do. Read this thread httpwww.benzworld.orgforumsr-c1...-engine-2.html
