Sideview mirrors no longer working after a car wash

Has anyone's sideview mirrors stopped working after going through the car wash with the mirrors folded? They have been working fine but took my car to get it washed on Saturday and no nothing at all. Fuse isn't blown and not getting any movement at all, not even getting a struggling motor sound.

Any other troubleshooting steps I can take to find the culprit?

Not sure if this has happened to anyone else or if it might just be a loose wire but wanted to get everyone's thoughts before I went to that establishment asking for them to fix it.

Well, good luck getting the car wash to take responsibility....even if it was their fault. Been down that road before with them sumbitches and it's difficult to prove anything but it may be worth a shot. I just don't go to a automatic car wash anymore...don't trust them and they usually have something that legally says they are not responsible for modified cars. Not many of us here who haven't done some kind of mod.

You would think based on the fact they worked before and now failed after the wash, you would be leaning toward something getting wet. Rain or even a Garden Hose are 1 thing, but the super high pressure from a car wash...who knows?

This electrical circuit is pretty basic really if you are familiar with schematics and can trace out the circuit. Maybe first give them some time to "dry out" and see if they start working. If not, and you're CERTAIN the fuse is good, may be time to pull the door panel so you can get to the mirror plug. Actually, you may be able to get to the mirror switch by just pulling the bezel so you can check for ground and voltage to the switch. Once there, check to see that you are getting a solid 12v and ground on the correct pins. The other wires are the control wires for the mirror motor.

Look at the schematic so you can get a good idea of which color wire/connector pin you're dealing with. If you don't have a basic understanding of electrical circuits or understand what the schematic is showing, then you may want to refer to a automotive repair shop and see what they can find.

Here is the schematic (I think) I used when adding the pwr mirror circuit to my car. I used it to create a harness using pigtails I picked up from a donor car. If you have heated mirrors, I believe the heated part was just tied into the Rear Defrost circuit. I don't see that listed in this schematic but pretty sure it was a pink wire. Good luck...

Edit - looking closer at the schematic and the defrost circuit, take a close look first behind the lower left kick panel. That is your ground connection and they are known to get loose and not make a good connection. It a possible issue and much easier to pull that panel then the door panel before checking elsewhere.

I have never had a powered mirror quit working after a carwarsh. In 40 years. But then I've never folded mine back either. I might hazard if no blown fuse that a connector got jetted apart??? Sounds like a stretch though. I think the mirror snaps out if done carefully enough, and you can poke around for issues.

And just MHO, but you'll likely spend more time answering questions from the gas station folks about why you folded your mirror (and of course hearing the brain-dead "not responsible for nothing" repeated 30x) v. coming away with anything more constructive or satisfying. In other words, save up your blood pressure for bigger stuff.

I really appreciate the information and insight you two provided on this. Looking closer at the mirrors when they are folded there is a rubber protector covering the motor so I am assuming that since they do fold back getting a car wash wouldn't cause them both to stop working. Fuse 40 is intact and I don't think it can be Fuse 35 since the power locks, windows and lamps are still functioning.

Since it is both mirrors not functioning I think it may be the power mirror controller on the door that is causing the issue. Looks like that will be my weekend project and I hope that is the culprit. Would hate to need to find two replacement mirrors, judging from other posts that isn't an easy or inexpensive task.

Thanks again for taking the time to help out!

LOL You can thank 4DoorSS for the helpful insights, I was more just giving you hell and tossing in a little experience curve regarding service station types. I admit it's been a couple decades since I used carwarshes eating parts with whirling plastic brushes or those pivoting spray arms in stationary bays. A few months back I had a mirror quit moving one direction so I pheuked with it long enough cycling it to the stops each way until it seemed to right itself back to working ok. I might have also ratcheted it a few clicks over toward center too.

I'll make you feel better with carwarshes. My old Cady was lowered a bit with sacked out SS coils so I never used the spinning whitewall cleaner near the finish because it scared me how close it gets to the body. So I use the 2 cheaper options without it. One crappy day I go through and see the light go on for it and just cringe - sure enough there's a thin thin thin abraded crease from the actuator along 2 lower body skirts. The counterboy is beaming and so happy with himself, "we're giving away the Premium warsh to all customers today only!" He and the manager look at the damage and you guessed it "We're not responsible for overhanging or loose parts, customized and altered vehicles, anything else or everything else. See the sign." They honestly reminded me of greased pigs looking for someone to chase them. I spent an hour running a wallpaper seamer along the back - almost all better.

So Heavy-,

3 months on, what was it? My PS just quit working altogether.
