I kinda have the same problem. My light works sometimes and not others?!?! Sometimes when im parked on a little bit of a hill it will come on and not go off for a little bit, and most of the time it just doesnt work. Im ripping the guage cluster out soon to put a new cluster with white faced guages, and i will check all the connections then, could just be a bad ground, dont know. I will keep u updated. Lata
Sounds like a very logical explination to me. I have the same problem, but thought the cause was different (though now I believe my problem is caused by what you just described).
I've known for a while that the asshat that I had replaced my parking brake cable (would've done it myself, but I needed it fixed quick and I wouldn't have been able to fix it for at least a week and a half) didn't reattach the switch for the light correctly. The reason I didn't take it back right then is that the light for the break hadn't been working consistently even before that.
When I took appart my center console for my Pro 5.0 shifter installation, I found that the switch was not reattached at all. The bolt and screw weren't there and the switch was (attached to the wire) in a small plastic bag to protect it. When I found it in this condition, I thought that the reason the light had been coming on while driving recently was that the vibrations of driving had shifted the switch into a position where the circuit was completed.
But now that I think about it, I have known for a while that my pads are very warn and are need need of replacement. This explination sounds much more reasonable.
Since my suspension parts are on back order, I guess I'll do the breaks this weekend.
