My wife backed out of the garage and the ABS light came on. She pulled back in to the garage and turned the truck off. She heard a "motor running" sound from under the drivers seat. I believe after researching on the internet that the ABS control module has shorted out. Pulled the fuse causing the ABS and parking brake lights to stay on. Very disappointed to hear there have been numerous failures of this module with no relief from GM. Was told by the dealer that the repair would cost approx. $1000.

Humming noise coming from ABS control module under left side rail. Pulled 60 amp fuse to stop from running. Contacted dealer and found that these modules go out all the time. $800 for parts and $250 for labor to install.after checking the internet I found this a widespread problem throughout the country. What will it take to get GM to fix this problem? there should be a recall on these units, this is a national highway safty issue.

ABS motor continues to run after vehicle is turned off.local dealer said he has to replace 1 module a week on the average. Why isn't there a recall?

- Maysville, KY, USA

With under 60,000 miles the ABS failed allowing the module motor to run constantly. Chevy mechanic advidsed pulling the 60 amp fuse as the cost for the module was over $500. Alos told to be careful drivng on wet pavement as the braking would not be as safe w/O the ABS sytem working. Contacted Chevy and negotiated the replacement of the ABS module, however upon agreeing to pay for 1/2 the cost the Chevy folks raise the initial $500 dealer quote to $899 which would not include the labor. As the safety is less when on wet payment I am L;ooking for a recall of this ABS system. The Chevy mechainc say it is a common problem wiht the ussual course of action being to pull the fuse and run with the brake warning light on. As I have leased this vehicle I have also been told by the leasing company I will have to repair the problem before it is accepted back when the lease expires. I have copiies of all the coreespondance with the Chevy folks itf you would like to see them.

1999 Chevrolet Silverado - ABS module runs even when the ignition is turned off causing a failure.

- New Castle , DE, USA

Failure of electronic ABS control module. Got out of vehicle and noticed there was the sound of an electric motor running even after the ignition was turned off. Found out that it is over $1,000 to have fixed. Just so happens that the dealer keeps several of these in stock because of the numerous failures. Problem was that mine was out of warranty by around 5,000 miles. Do you think GM would offer to cover this... of course not. What a joke.

I own a 1999 Chevy sivlerado. On 12/27/02 I started my vehicle after leaving work and noticed that the ABS light went on. After I got home and shut the truck off there was a noise coming from under the truck (sounded like an electric motor running). I drove the truck over to my local Chevy dealership and one of the tech's listened to the truck and diagnosed it as the ABS module. I told the service manager to call me with a quote for repair. He called about an hour later and said that it was the ABS module, and it would cost around $1000 to repair. I declined repair as I was told that the brakes would function fine by just pulling the ABS fuse (the ABS wouldn't work, but the brakes would work fine). Trying to negotiate with dealer and/or GM on repair cost. Truck has 60000 miles, so they are saying "out of warranty". I said "stand behind your product!" saw these other instances of the same problem on this web site, so I thought I would add mine. Looks like they have a problem with the ABS on this vehicle and they are not taking care of it.

We have been having problems with our ABS since we purchased the vehicle. At times the ABS would suddenly engage when it wasn't warranted (I.e., in the middle of summer on a dry road, slowly approaching a stop). Then suddenly, backing out of the driveway the ABS light came on, along with the buzzing noise. The only way to stop the noise was to pull out the fuse to the ABS system. Upon researching the problem on the internet, I've noticed that this is a very common problem among other 1999 Chevy Silverado owners. Something is obviously wrong with the ABS system in these models. General Motors won't do anything about it. The unit costs $1000 to fix, which by the time the defect usually shows up, warranties don't cover. My guess is that by the time someone takes this problem seriously enough to take a look into this and realizes that there is a problem with the ABS system in the 1999 Chevy Silverado, that someone will have gotten hurt or even worse...a death will occur because of it.

ABS pump continues to run after ignition is turned off. I called norman frede Chevrolet in houston Texas and the service technician told me to take the 60 amp fuse out from the distribution center under the hood and bring it in. He also told me that this is a $600 part alone. He said this is a common problem with 1999 Silverado. If its so common, how come there isn't a recall on this yet. It still isn't fixed.

ABS motor continued to run and would not shut off. Had to disconnect the 60 amp fuse to prevent battery from running down. Am told that the ABS module is defective and will cost well over $1000 of my money to repair - this has not been recalled. This from a Chevy with 80,000 miles"? I've discovered that this is not an isolated incident, that this is a common defect with this vehicle. Why isn't this being recalled? what else can we do" M.E.

Electronic brake control module went out

- Chicago, TX, USA

6 days after replacing tires with same size tires, I got in my 99 Chevy Silverado truck and started it up. A strange humming noise started coming from underneath the truck. Upon further investigation I found it was coming from the ABS control module. I called the local Chevy dealer to verify what it was and they new instantly that it was indeed the ABS control module and it would have to be replaced.

- Clovis, NM, USA

When consumer turned off ignition and exited vehicle, he heard a noise coming from engine area, indicating that a system was still operating. Dealership examined vehicle, and determined that control module for anti-lock braking system had failed, which resulted in continued operation. Replacement of module was needed.
