I have a 2002 Tahoe LS with 65,000 miles. I purchased the vehicle in 2004 with 17,000 miles. At that time it had a very intermittent noise, (squeak) that sounded like it came from the drivers side under the dash or seat. The noise is no longer intermittent but constant. I've done everything to find this noise except remove the drivers seat. (it's a power adjust seat). Has anyone else had this type of problem and what was done to fix it?
