I just joined. need some help with my daughters 2003 blazer. I just replaced all the break pads - it had and still has the abs/break light randomly coming on. I was told to replace the pads that not the problem. anyone have some ideas.

 

Have you tried resetting the computer? Worked in my Blazer. Although mine's quite a bit older than yours. could be a dirty sensor or something like that even. but i'd try resetting the computer first (assuming you can do that...i don't know anything about new blazers).

 

how do you reset the computer

 

Disconnect the battery for 10-15 minutes.

As far as your problem, it could be a broken front WSS (wheel speed sensor) wire or a dirty WSS in the front hub. Is the truck a 4wd?

 

yea its a 4wd 4 door - perfect for a college kid

 

hey man, i had the same prob.
if resetting it doesnt work
take off the wheel and look on the wheel hub for a small black box
there should be one or two screws on it
take it out and clean it off
mine had some grease on it
once i cleaned it the light never came on again

 

Whats up guys, I'm another new guy love my Blazer. Anyway I have a 99 ZR2 Blazer and I had that same problem. What it ended up being with mine was a bad speed sensor. It kept troughing on my abs light also. So I replaced that and it has not come back on yet.
