Repairing non working rear slider window on Lariat easy way
I came to the conclusion that the rear window stops working when i wash the truck or go through drive thru car wash, due to the soaps and wax in the water that trickle their way into the cable.(my theory anyway) Some how it causes a glue like substance and causes the motor to stick(the cable that is wound up inside motor that moves window).Long ago I removed the seat and gave the motor a good tap with a hammer and it started to work. I even went as far as removing the motor and shooting alot of lubricant inside, but still sticks after a couple of months when i dont open and close it often after washes. So this is what i did today and it workd for me. May work for you. Please be careful and this only works in Lariat with fold down armrest. To check if this indeed is your problem your interior lights should dim when hitting the switch to open. This means you have power to motor and its stuck.
Locate center of height and width
With fingers press really hard and locate a "bump" . It wil be in center twords the bottom. It will be the only bump. This is the center of the motor.
Right here is bump(center of motor)where sdriver is pointing
Use a hammer to hit the bump dead center, not to hard ,a good whack(not resposible if u brake something. May have to play with it.Motor case is metal and braket it bolts to is metal. At the same time............
Have someone toggle the swith to open as you hit the motor.
Window should open.
Lube all the cables on both sides of window with lubricant to help the cable. Hope this helps someone. It will also help to open close the window after a carwash so it dont stick. Even a couple of hours later. Remember also to lube cables often.
its a little sledgie hammer that i used and you are hitting far away from glass. The motor sits on bracket that hangs and will ABSORB the hit , the motor part does not touch the rear wall. DONT HIT IT WITH ALL YOUR MIGHT. Tap hit it. IF you were to remove the rear seat and open and close the window, you will notice that the braket will flex back and forth. The Motor hangs in mid air.
I have 85,000 miles on my truck, and my slider stopped working shortly after the warranty expired. I have to say that this is such a simply fix. I had concerns about cutting the fabric, so I used the rubber end of "The Club". I gave it a gentle bump and was surprised to see it work.
this is a reaaaaaaaaaaaaaaaaaally cool trick, and will keep it in mind but mine's not stuck yet. Have never lubed anything, so where exactly does one put the lube, and do you have to dis-assemble anything first? & what kind of lube? WD40 ok?
Glad it worked for you xl1200. It realy does not take much ,just some light continous tapping while pushing the open switch. Big Red Lariat , I would shoot some silicone lube on the window track itself which is plastic and wd on the cables. They are located on each side of the slider on bottom part.
I never said it leaked, as there are no water stains on seat or carpet. i said my theory is that it TRCKLES ( couple of drops , not water pouring in)through the bottom part of the slider during a car wash.
I have a good idea how moisture is getting back there...I did all the custom work and posted a vid on how to remove your back seat. In the back there are 'pressure relief' vents in the back. They aren't the heaviest plastic vents so they open with a simple door closing.
It could be quite possible that they are allowing some type of condensation into the rear of your seats and since there is a 'back drop' behind the seat you would never see it unless you removed it like me to install an amp...it now makes sense why there was some buildup on the amp terminals....
Check out my vid and pause it at 1:37, you will see a small black shadow just to the right of the amp..there is your 'window of oportunity.'
