Dead blower motor plz help

[Vincentjr]

So I have a 95 E3 20 station wagon I call it Satan’s wagon because the vin ends in 666. I have heat that blows through the vents I got my AC system to work although on a sidenote I am having trouble with my cooling fans I have been through this forum for a while and done many many tests I have high speed and low speed I’ll try to make a different thread for that but moral of that story is they don’t ever come on and I don’t overheat . I don’t think my push button is bad because I hear the flappers move around the motor is good and I was able to jump it from the regulator plug in a three pin plug behind that is very clean I’m gonna have to get a new voltmeter to do those tests I’m at a total loss to save this green wagon please any help is very appreciate it

 

[Vincentjr]

So from the three pin plug that goes to the resistor I put power to black and ground to red and the fan spun on what seem to be high other than that I have been tested the fan itself powered blue and ground to the other one

I'm confused. Your title says "dead blower motor" but your post says you have high and low speeds. You can't have a dead motor plus two speeds, so which is it?

Also, have you checked the 30A strip fuse located at the driver side strut mount?

Yes I’m in Process of making a thread for that I have a good motor potentially a bad regulator the 30 amp strip fuse is in good order as I have switched it out for a new fuse holder that I can swap regular speed fuses in

I have a 95 sedan with all the components that are working that I’m going to for the millionth time pull the wiper off and see if this fixes that issue will update after

Have you checked (with a multimeter not just visually) fuse #7 in the main fuse box? This 16 amp fuse supplies power to the dash board PBU (push button unit).

I’m probably gonna buy a new multimeter today because I’m not sure where my other one went but I have not tested it with a meter yet. I have switched out the 16 amp fuse for 25 which was suggested in another forum. And offhand what reading should I be getting from that fuse specifically

Sorry- you put a 25A fuse where there should be a 16A?

Reverse that immediately. It will not solve your issue, and is a fire hazard.

NEVER upgrade an smaller fuse to a larger fuse. I don't know what other forum claimed this was a good idea, but they are wrong wrong wrong. If it's not a factory instruction, all you are doing is increasing risk of fire and damage to wiring.

Jokes! All jokes!

@Vincentjr if you have replaced the blower motor regulator already AND you have confirmed via electrical testing that the blower motor runs, then follow this thread. Please read all of it to understand the context. It could be the ignition switch is not powering the branch that allows the blower motor to run.

Another Bad Blower Regulator? [Solved: Bad Ignition Switch] | Heating and Cooling (Interior HVAC systems)

I just installed a new Kaehler (KAE) blower motor regulator, after the one I had installed just six months ago went bad. The motor was also installed six months ago and is from the dealer. At first the low speed stopped working, so I was running in auto and high, then the auto and high stopped...

So I am a bout to read that thread but I bench tested the ignition switch and made a jumper from my firewall three pin plug to my parts car that everything works on and I have zero blower so I’m assuming I need to do an ignition switch and I also fixed fuse 7 with a 16amp instead of a 25 amp

It sounds like you are making some progress and the parts car I am not sure of but I think you are saying that the blower motor works on your parts car and you connected the 3 pin port on your car’s firewall to your parts car and your parts car wan’t blowing I am not really sure what you mean by bench testing the ignition switch but you should read that thread anyways and besides changing fuse 7 from the OE size to a bigger size is a poor idea

I tested the working setup with the wagon that’s having the issue I didn’t get anything from it I’m assuming my ignition switch is defective

 

[gsxr]

Try moving the ignition switch slightly back and forth and see if the blower comes on at any time and if it does then yes the ignition switch is probably defective

Before I go doing the ignition switch I’m going to test my regulator and blower from the parts car just to make sure that it’s not a regulator issue as well as ignition switch will get back to you guys later

 

[Vincentjr]

Update for everyone I have tested the wagons regulator from my sedan which is the parts car where everything is in working order and I got nothing out of the blower on any of the speeds when I was attached so it looks like I will be pulling The wiper out for the hundredth time and I’ll also be digging into the ignition switch for the third time on this wagon

 

[Vincentjr]

So I pulled the pushbutton the regulator the motor the whole ignition with key and the headlight switch because mine is broken I’m hoping all of this will fix my blower issues but I noticed last night because I leave my PB you in auto and on defrost with heat on maxxed that the circulate all button was flashing and it sounded like the HVAC box was making a clicking sound has anybody ever had that issue with the circulate button???

Not 100pct on this, but I think a blinking recerc light is the HVAC equivilent of a

I hope some of the Legendary vets chime in on this one because this is the second time I’ve seen this happen

 

[Vincentjr]

HUGE UPDATE FOR EVERYONE!!!!!! thanks to everyone who chimed in my ultimate fix was the whole ignition with key and switch and regulator. Now to work against the memorial day weekend rain now I can address why both front seats do not slide front and back stay tuned for the next thread thank you again to everybody who help me and put my fears at ease

 

[gsxr]

Awesome! If the seats move in other directions but not front & back trying cycling the switches back and forth dozens of times sometimes this will resurrect a flaky seat switch

I will try that shortly I have finally seen the twin electric fans work for the first time since I’ve owned this car as well because I’m running the AC and also if you would like to private message me your PayPal I would love to give you a gift for all of your useful information sidenote are the motors that go for the lower part of the seat known to go bad and fail I peaked around the site a little bit but I didn’t really find anything for it yet because I’m still learning how this board works

 

[gsxr]

The seat motors almost never fail but the switches are known to cause problems, so start there first especially if the seats move at all (backrest, headrest etc). Might be some more info on seat troubleshooting on PeachParts and BenzWorld forums, I don't think there has been much discussion on this forum about seat stuffs...

 

[gerryvz]

There has been some discussion and fix-it around seat cables that have disengaged from the motors.

Yeah I have back and head that work on both front seats I’ll check out peach parts and report back

@gsxr, I replaced my seat switch for the driver’s seat because the old one seemed goofy. Push to go forward and it would go backward and so on. The new switch did not help. Of note every time I have taken the car in for some service (not lately) the seat was working correctly again. The Tech that owned the shop was 6’-3” and had to change the seat position and it always worked for a while when I got it back. No idea what he did that works temporarily.

Anyway, Next time I take it to him I plan on having him fix it permanently. Since my car was out of service for 3+ years it’s time to take it back to him.

Just my experience with the driver’s seat.

I had a problem with the passenger seat tilt function. It wasn’t the door switch or wiring. It turned out to be the seat plug. Unplug the plugs and count the male pins and check to see if there are the same amount of female sleeves. If the male pins are not perfectly aligned when inserting the plug they will push the female sleeves down into the plug and they will not make contact.

The plug cases are hinged and pop open easily. Reseat the sleeve and slowly insert the plug.

I have also experienced the switch performing the opposite function on my higher mile car. Cycling the switch as advised seems to cure the issue.

 

[Vincentjr]

There has been some discussion and fox-it around seat cables that have disengaged from the motors.

So I did the easiest thing after trying to peak around the web and not really getting anything, so I pulled a good switch from the parts sedan and bam still in the same boat…

So the odd thing is it’s both front seats that just the forward backward and elevate on the lowers are in operable and I’ve seen a bunch of different stories that kind of touch on what I’m getting but not really

This was going to be my next investigation I was trying to avoid pulling the whole seat

You should be able to do this with seat in place. Unhinge the pleather cover below the front of the seat and your plugs will be accessible.

Just seeing this now ironically I’m sitting in that wagon I’m going to check that out
