Driver side rear door squeak

[stevieray36]

I have 3000 miles on my 2004 Extended Cab HD w/Duramax engine. It has developed a squeak in the rear door behind the driver. It sounds like styrofoam rubbing together. Has anyone else had this problem and if so what was the fix?

get a can of silicone spray lube and treat all of your door weather stripping.That will take care of it.

Yep, shotgun is right. I had that problem on my 2000 Z71 ext. cab doors. I brought it to the dealer and that is what they did. Never had a squeak again.
