Rear window very slow--here's a fix
"...90% of you all probably already know this so I guess I'm talking to the other 10% of us who don't/didn't. My rear window has been giving me problems for the last 4 months. It would go down a few inches and it would get stuck. Then I would either have to rock the dash switch back and forth to get it to go down or go to the back and use the key with one hand and push down the window with the other---Very frustrating.
1) First roll down the window, drop the gate and take off the inside panel (about 8 philips head screws) covering the tailgate. You will see pretty much nothing but glass after doing this.
2) Then manually flip the latches so you can use the key to roll the window back up. ***Very Important*** Put something under the window to support it--sawhorse, lawnmower or whatever. The weight of the glass could cause it to break when rolled up with the tailgate down.
3) After the glass is up you'll have access to the inside mechanisms. If you bend over and look at the underside you'll see a couple of arms that attach to two 6"-8" pieces of channel. These arms move along the channel to raise and lower the glass.
4) Get some good grease and smear inside both channels. You don't have to glob it in there just put enough that it goes completely on and along the inside of the channels.
5) Roll the glass back down.
6) Put your inside panel back on.
7) Pull your tailgate release handle one time to make your latches go back to the open position and close your tailgate.
8) Now roll up your window and see if it helped any. Mine goes up just as smooth as ever now. It doesn't slow down a bit.
BTW, this took about 45 minutes start to finish..."
