Weird one for you all!
I have a 97' S-10 Blazer 4X4. Yesterday I had to slam on my brakes to avoid a yuppie crossing (Honda.) After that happened I turned around and went back to educate this "gentleman." As I drove off I heard a rapid ticking/clicking (like a rely) behind the glove box area. At the same time of the ticking/clicking the DTR light dash symbol flicked. My regular headlights were in use at the time.
Fist I thought it was just the computer re-grouping, but it happened 2
3 more time on the way home. It didn't seem to effect anything else. There were no "Brake" or "ANTI" lights on either.Today I drove 60 miles and heard nothing! My headlights were not on today though. Do think it was just the OBC resetting? Any others had this or any input?
