I was wondering if anybody has had the same problem that I have. On my '91 K1500, my parking brake light seems to flash randomly, except for when the parking brake is applied. The guy I had bought the truck from in November, said that it was the parking brake sensor. But when I went to a dealership to get a new one, they didn't know anything about a parking brake sensor. Also, if I disconect and then reconnect the battery, the light wont flash, it will just stay on, then a week or so later, start flashing again.

my dads s10 did that. check the parking brake switch. its attached to the bracket that the pedal is mounted to - when the pedal is pushed down it stops contact and turns on the light. on his truck the bracket had gotten bent a little so the switch was messed up. or if it really annoys you, disconnect the switch. its pretty obvious your parking brake is on when you try to drive!

Mine did that with a bad switch, I don't know if unplugging it is a good thing though (may or may not hurt). What I do know is the same circuit is used so that when your brake fluid is low or low pressure, the switch in the proportioning valve sends a signal to the parking brake light switch to let you know if you have a problem (mine came on when I cut a line on a rock) so I don't know if unplugging the parking brake switch will defeat the low brake fluid light if unplugged because they share the same circuit (could be a bad thing). Just something to consider. It's like hearing a whine from your rearend and turning up the radio to drown it out. It cures a symptom, but not the problem and may lead to a bigger headache down the road.

I have a 90 GMC and have the same problem. I talked to a mechanic about it and asked me if I needed a brake job. I told him I did and he said it had something to do with the rear anti-lock brakes. Some sensor for that. I still haven't gotten the brake job yet due to mot enough money so I can't be sure if he was right. He was a trusted mechanic that I was calling for advice on something else so I don't know why he would lie. But I was planning on selling the truck to get a newer one with less miles and an extended cab. So I may never find out.

P.S. By the way. All of you that helped me with the fuel pump problem a few months ago. I think my new one just went out this morning.

That which does not kill us, only makes us work on the truck more!
