About a 9 months ago my ABS and Break light started coming on and would turn off on it's own. I took my Blazer in for some other repairs and had them take a look at the ABS sensors. They told me the sensors were fine and the breaks work just fine. It appeared to the related to the warning lights, the computer was reporting a problem that was not there. To fix it they needed to rebuild a part (don't remember what part), he said it would take a few days and would cost about $500.00 (If I had the dealer repair it the cost would be more than $1500.00). Since the breaks were working fine and I did not have the money to fix it I decided to let it go. I am ready to have it fixed now but wanted to know more about the problem. I wonder why this issue has not been recalled.
The ABS light comes on while driving. Sometime the ABS will kick on for no reason. I will be coming to a stop on a dry paved road and boom the ABS kick on. I beleive it is on one side only cause the vehicle will pull very hard to one side. The problem has no been addressed yet but I will be taking a lok at it shortly. IF any one else has had this problem and fixed it please let me know.
Start out abs not on after driving comes on and when car is shut off and restated will go out but will come on at any time
the abs & check engine lights will come on at same time while driving.i have stopped & turned car off & when i start up again the lights are off.I haven't done anything to try & fix it yet.
Abs and brake lights always on. Service engine soon light always on. Pulled relay for abs because module was buzzing
00 blazer brought It for 550.00 abs light was always on and front driver side tire would lock up. Went to junk yard pick up a module for 10.00 put it on in 5 ninutes, Solved every thing.
The ABS light has always been on since I bought the car 3yrs ago. No matter how many times I take it to my mechanic, cannot get it to shut off.
ABS engaged when breaking on ice at an intersection while in 2-Wheel Drive. ABS light came on and stayed on. Parked to take care of some busines; started vehicle and ABS light came on. Next day, started vehicle, the ABS light did not come on. Called Al Serra dealership for appointment. Service manager said it would be difficult to diagnose if the ABS light was not on, but I brought it in any way. Said there was a problem with the ABS but that the part was no longer manufactured, and even if he could find the part it would run $3000 for the the repairs. So it has not been fixed at this point. Not finding anything on line indicating lack of parts or that kind of expense for ABS repair.
I have the same problem it's the light coming on then staying on and Los when input on bikes my blazer jerks relate to right side. Have replced everything and nothing has helped so far.
My abs light came on after I got my brakes calipers an roders I got it done at a shop I pulled the fuse an the abs light stayed on so when I was backing out of the driveway hit my brakes an pumped them light went out seems fine now
