Is there a known problem with late Gen 4 power windows running slow or in my case sometimes just stops 3/4 of the way up ? If so , is there an easy cheap fix. ?

 

Try spraying some silicone lubricant on the inside of the rubber guide rails if there's not a fabric like material between the rubber and the window, the rubber can get old and in some places start to stick to the window causing it to have a hard time rolling up or down.

 

Thanks I'll try it. Sound like the lub will get on the glass though.

 

Yes, a small amount will, if you really don't like having a little on the window but it works well after you spray the silicone on you can buy new rubber guide rails, just a cheap thing to try first
