My rear windows were very slow up and down, so I sparingly sprayed "STP Silicone Lubricant Spray w/long red tube" in the window track along the sides, and it fixed 'em. It didn't seem to work right away, but the next day they were much better. Just thought I'd share. (Did the front too, much faster now!!)

 

Cool...
I need to do my two rear side windows as well.

The fronts & the tailgate are both fast, while the two rear ones really lag.

 

I need to try that on my fiancee's Honda Prelude. Her sunroof is getting slower and slower to close.

 

yeah, i need to as well... i hate it b/c one window is faster than the other.... thakns for the tip '95
