power window switch clean up

[joe5]

So I had this problem with my power widnows in my 92 loyale. Just to be clear the problem is now FIXED. But figured I'd post what I found to help the next guy.

 

The problem: Both passenger windows would roll down but not up.

The fix: Cleaning up the switch on the door.

 

So after checking fuses, relays and other common suspects, I found the culprit to just be poor contact at the switch on the door. Probably a more experienced mechanic would have checked this earlier but alas, I am not that experienced. 

 

Anyway, I got some pictures here so the next person can know what they are getting into. Beware, some of the pieces are tiny and the switch kind of falls apart when you take it out. Be careful so your not diggin in the dirt! Maybe this is typical of electrical switches but Ive never taken one apart before so there ya go. 

 

I didn't take pics of removing the switch but its easy, just take the panel off the door and disconnect it. 2 screws hold the switch to the inside of the door panel and then the switch is free.

 

Take off the plastic cover and take out 2 small screws which hold the switch together. 

 

The two halves of the switch...

 

And here are all of the little parts individually.

 

Also, be careful removing the screws, they thread into a plastic piece which break easily. And you need them to hold the switch together.

 

Interestingly, the contacts were not obviously corroded. But a quick little buffing from the tip of the screwdriver made all the difference as now the windows work great. 

 

Hope this is helpful.

Been there done that. Pretty easy job really. Ive also had good luck spraying pb blaster in the switch and working it back and forth

Yea overall it was super easy, just wanted to post some pics because pictures are awesome. I didn't use pb blaster but it soudns like a good approach, I just scored the surface with my screwdriver to scrape off the grime. Probably better ways to treat it to keep it cleaned up longer.

Yes, me too... I did the same in 1998 during the Hurricane Mitch; I was "Locked" inside the house for several days then due to the huge  rainstorms. 

 

A pair of those switches had broken plastic housings, so I fixed them with JB Weld and I can not open them anymore... They lasted alright more than a Decade after that, and started to fail again in 2008; so I had to be Creative, since I can not open them anymore...

 

I used "Electronic Contacts Cleaner" (the kind used for cleansing computer mainboards and other delicate components, and is Plastic Safe) in Spray, without disassembling anything and worked really Awesome. You only need to flip the Switch completely to the Down side and put the Spray's Straw the nearest you can of the Opening at the other Side, blasting quick bursts of cleaner fluid inside the Switch; and repeat the procedure with the switch flipped to the Up side; then let the fluid to evaporate, prior to move the key on the ignition.

 

If the Switch remains wet, they'll emit a mute noise  the first times those switches are used, and it dissappears quick. I never disassembled those Switches since then, the Spray works great.

 

Kind Regards.
