Thread: Electrical problem?

I have a 2002 Trailblazer. For the past several months, the anti-lock brake light has stayed on sometimes. The local dealer said we needed a new anti-lock module (at a cost of $900+) but the problem appears to be electrical, not the anti-lock brake module. If the antilock light stays on, the heating/cooling fan does not work either. Starting the car before putting on seatbelts prevents the light from coming on - sometimes. It may go out after a few minutes of driving; other times it stays on for the whole trip. It is very frustrating. Anyone else had this problem?

Electrical problem? - Trailblazer anti lock brake light
Does this problem affect the anti-lock brakes? That is, do they still work? I'm not telling you to go out and slam on your brakes, but if you have needed to hit them hard in the recent past, did the anti-lock unit kick in? You'll know when the kick in.
I've not heard of a problem like this before. Maybe someone else out there has?

I had a 99 suburban with the anti-lock brake kight staying on and mine was related to the abs sensors at the wheels sticking a tad, they just needed cleaned and adjusted. Make sure you do that first, much cheaper than the module. That also sounds really high for a module!
