Hey guys I just bought a 2k Silverado ECSB and the only things wrong with it is that there is a whistle coming from the back windows at 45MPH+. Anyone have this problem/solution? And I need a **** for the stock CD player. The one for the volume/ on and off. TIA, boot

 

weather stripping is probably catching, or their is a whole in it. Could be a 2nd rear window, last one could have been broke out or something. Probably didnt seal it right. thats my guess, had that problem with my winshield when I put a new one in.

 

I've heard of similiar problems with the EC's. I think it's due to the weather stripping. Also, people have complained about a loud "wooping" sound, kinda like a helicopter, when at highway speeds with the windows are open. There may be a TSB about it. Check over at the 99+ truck forums at www.chevytalk.org. They'll help you out for sure.

 

the truck u bought might have been in a wreck. my trucks had a bad whistle too ever since it got hit

 

No the truck is clean as far as I can tell (three different sources). Do the latches ware out? Mine don't really lock, they just kinda fold in but don't snap in or anything. I mean they seem to stay in place just curious is all. I have not however seen any leaking back there from recent rain so I think it's just a small whistle.
