I put my 99 Silverado Z71 in reverse this morning to back out of my driveway and heard a buzzing noise, like the sound you here when your ABS brakes are actuating. I looked at the dash and my ABS light was on. I mashed the brakes a few times hoping it was just something sticking and would break loose but it didn't. I parked it and shut it off and the noise still remained. I got underneath it and saw a small motor on the driverside, inside the frame rail, that was running. I tapped it a few times with a wrench and it still wouldn't stop. I ended up unplugging the battery. Any ideas what I might be looking at? Anyone had this problem before?
99 Silverado ABS Problem

As usual, a very common problem. Your ABS module has gone out. I don't think it can be repaired, only replaced. If I remember correctly, it costs about $600 to fix at the dealer.
In the meantime, unplug the ABS fuse under the hood. Keep in mind though that this disables ABS altogether.
That really sucks.

See the other post by ~~AAJakeleg.....it is your ABS module. There is a relay that happens to be an integral part of the module, and it has stuck in the on position. You have to replace the module.
