I have a 05 Lariat and the windows just quit. I've checked the relay and it's good. I've checked all the fuses and their good. The lights on the switches will some times flicker, sometimes they are out completely, and tonight they were all illuminated like they are suppose to be. Everything else still works in the truck, even the sunroof.

Any ideas?

 

I would think it's the window motor which as maybe burt out !

 

All four windows quit working at the same time though

 

Sounds like the window switching station on the armrest for the power windows is faulty if none of the windows are working. The only real way to test the system is to go to each window motor inside each door with a multimeter and see if you are getting 12 volts at each motor when the switch for that window is depressed. If your not getting 12 volts at the motors, then the contactors inside the switches are either not making contact, are dirty or are faulty. You can try using contact cleaner on the switches if their contactors are dirty and they should start working again. Hope this helps.

 

It certainly does. Gives me a place to start. Thanks

BTW, I see your from Springfield. Is that Springfield by Lakemore, Sanitarium Rd Springfield?

 

Likely your switch in the armrest is bad. Mine's starting to act flakey too. I have to push it 2-4 times to get the window to work sometimes. Too bad my warranty just ran out earlier this year :-(

 

theirs a good fix for the window that button that needs push a few times to work...did it for my truck and now they work ever time and even go up faster than ever

what you do is remove the hole switch from the truck remove the trim off with a small screw driver ...then left with the switch and then pry off the buttons...then on the sides pull the taps lose then you can see the contach points clean with a file

if you look theirs a post on it with pics
worked great for me and same 80 bucks for a new switch at the dealer
