2004 Silverado, after the turn signals shut off, I get a dull thumping noise behind or near the glove box area. It almost sounds like a relay still cycling, but not sure. I think I had a similar problem on a '98 Blazer, but can't remember what the solution was!! Anybody??? Thanks.

 

im sure its normal. because ive heard that plenty of times in trucks ive driven in at my work.
