Most recent owner complaints, unedited.
Why does this work on my 1999 chevy & not my 2002 chevy?
My brake lights went out. The third brake light. As I owed a 2001 gmc jimmy that had the same problem that was covered under a recall I knew that the multifunction switch in the steering column was the problem. I went to my local chev dealership (koehne chev) in marinette wi. They said there was no recall one my vehicle. I asked about the three tsb and they said they don't have to do anything with a tsb. I know this is a ongoing and a safety issue (no brake lights). The part number on the switch that I took out is 26096832. There has to be hundreds of thousands of gm vehicles with these switches in them with the potential fatal accidents waiting to happen!!!
