Title: Power windows
Post by: Ronning on May 02, 2018, 11:16:55 pm

Have a 78 Sierra classic. Power windows and locks. Windows work perfectly when the temperature is cold or mild out. As soon as the truck sits in the sun or gets above a certain temp the windows become inoperable. Again, truck cools down and boom they start working. Any ideas or avenues to get into?

Clean and lube the channels, replace any worn out run channel strips. Adjust the run channel to ensure its just right.
