Hi folks,
I'm looking for some help with this issue. I've done some searching around in the forums and have come up with a couple of things to check but I'd like to ask if there are any electrical experts out there.
I don't know much about electrical in a vehicle and I don't know how to use a voltmeter properly, although I have one. And I have a test light. So I have the tools, now I need the knowledge.
The issue:
Both of my windows rolled down the other day, but now they won't roll up.
When clicking the button on either door for the window to go up or down, the motor doesn't run. However, the cab light dims just a tad and the voltmeter on the dash dips down quite a bit. It does this if the key is in the ON position or if the engine is running.
I thought I might get lucky by replacing the 30 amp fuse ($5 at Pep Boys!
) and that didn't fix the issue, nor did it change the symptoms.
The master switch on the drivers side has never worked for the passenger window since I bought the truck several months ago.
The passenger switch has always worked, up until recently. It's flaked out a couple times and not worked at all. I'd leave the truck sit for an hour or so and then be able to roll up the window normally. This has happened twice before it stopped working entirely.
When I first bought the truck and started tackling this issue, I took apart the master switch from the drivers window. On the master switch, the switch for for the passenger window is physically worn out. Using a pencil, I could click down on the contacts and roll the window up or down. (Don't use a pencil though, it'll start smoking...lol) My truck has other more important issues, so the window thing went to the back burner. Now this one requires to be fixed.
I'm looking for suggestions as to where to start and what to do? Other posts I've read about this, say to clean the switch with contact cleaner. Will MAF sensor cleaner do the job, too?
Other posts had mentioned that it's a grounding issue but I don't know how to trace one down.
I'd appreciate any assistance with this please. Sorry for the long post, I wanted to be as detailed as possible. Thanks for your time!
EDIT: I forgot to mention. Every other electrical component on the truck is working correctly.
