hey guys i got a question ive got a 2001 blazer ls 2 door with the 4.3 v6 and 5 speed transmission. ive changed the wheel bearing rotors breaks all those little things every once in a while the abs and break lights in the dash will come on most of the time when its wet out when the lights come on nothing changes with the way the breaks work the abs still works and it stops just like it normally does anyone have any idea what might make it do that and any way i can fix it thanks

 

Pull the ABS codes. That will give you much more info than I can!

Good luck!

 

Sounds like a wheel sensor problem to me-kristoph30 is right,but first do a physical exam at all 4 corners,you might find something as simple as a cut sensor wire,happened to me!

 

My 97 doesnt have individual wheel sensors on the rear. Did they upgrade the system to have individual wheel sensors?

 

check the system for codes , i changed my pads yesterday and my abs stopped coming on . well my front pads were shot tho and my caliber was frozen.
