General Motors has indicated that pretty much every 1999 Silverado will have this defect. The ABS motor will stick on and not shut off even if the truck is off. You have to pull the fuse out. The dynamic rear proportioning system is now not working. Which balances the front to rear brake balance. GM know this part is defective and has recalled it on the 2000 model year but not the 1999 model year. I am sure you already know about how many others are like this and could cause the truck to handle different leading to possible accident. Repair cost are around 1000 dollars and many people will not have it replace.

I have had three problems with the ABS brakes. First problem was the truck would not stop while towing my tailer with electric brakes and doing 10mph on dry, level road. The second was same as first but without the tailer. Both times the dealer found nothing. The third was that the rear rotors had rusted over and the pads were down to the metal backing. This was all before 21,000 miles and I had to pay for the pads. GM only paid for the rotors. Now the truck is out of warranty the module has gone bad and after several phone calls to GM they said they will only pay 30% of the repair bill and I will have to pick up the other 70%. talking to the dealer they tell me GM has a problem and GM knows it. GM told the dealer the trucks were not designed for the weather in the northeast (snow, salt, water) so why are they selling these trucks where they know their going to have problems. This problem is going to get someone hurt if not kill if someone doesn't do something about it. A mechanic friend at the GMC dealership in town said that the location of the ABS system is the biggest problem. He also said that they have replaced quit a few units in the last two years in GMC trucks. Why don't they do a recall and fix the problem.

ABS module failure ABS module runs continuously and must be shut off at the fuse or it will run down battery. The part must be replaced as a dealer part (no aftermarket) at a cost of $1000 plus. Dealer indicated that failure is a systematic problem with the 1999 model. Has been corrected for 2000 model. This should be a recall item!

Driving to work, ABS light came on, ran code check, C0265, C0267, C0281, and then told parts would be $850. Decided to expensive to fix and not worth it with the number of problems the state inspector had seen. DT5

ABS module failed at just over 43,000 miles. Dealer said this was common problem with '1999 Silverado. Contacted Chevrolet to question why recall has not been placed or if they are providing assistance with repair cost due to the failure on a newer, low mileage vehicle. Told by Chevrolet there was nothing they could do. Researched problem on internet and discovered this is a widespread problem for this truck. I feel as if Chevrolet should live up to the high standards they claim and take care of a problem of this nature.

ABS pump continously runs. Pulled ABS fuse so battery would not run down. Took truck to local shop where they ran diagnostics. Informed me that both the ABS module and pump needed to be replaced. This is a very expensive repair for a vehicle that has less than 50,000 miles on it.
