ABS & Buzzing
01-16-2005, 08:30 PM
While driving home, my ABS light came on. When I pulled into my driveway, I turned off the Tahoe. But there was a load buzzing noise coming from the brake area (even after the Tahoe was turned off). What is wrong? I have no idea when this buzzing noise is going to stop.

its the motor for the abs, these trucks are known for this, you can pull the main fuse for it under the hood or get it fixed for big $$$$$$

Thanks for the response. I pulled the main fuse for the ABS and the noise stopped. Does pulling the main fuse for the ABS affect anything else or can I just leave the fuse unconnected?

you can leave it out but obviously you will have no ABS. my uncle had the same issue and gm said it was 1000+$. You may be able to get a used on somewhere.

Just went through this with my 2001 Hoe. Give you a couple of options now that I know what I could of done. It is a expensive fix at the dealer.
Normally it about a $850.00 part and $148.00 for labor. The dealer cut me a break and did it for $780.00. For that price I thought they replace the entire ABS coponent. I was shocked that they only replace the module. The buzzing you hear is the motor running. Apparantly the module shorts out and causes the motor to run. Remove the ABS fuse, the vehicle is still driveable and safe, just don't have ABS. You may feel some pusation in the petal.
Option 1: Contact your GM dealer parts department and get the part number for the ABS module. They will need the last 8 digits of your VIN number. Go to www.automotiveforum.com. You can order the part for about $488.00 with shipping charges. These are original new factory parts from a Chevrolet dealer. I order several times from them. Make sure you have all proper information, parts like this are not returnble. You may want to change it yourself and refer to website below for removal and install or pay someone.
Option 2: This is the one that floor me. Go to www.modulemaster.com. They show you how to remove the module, though it does look like a pain to get to.You remove this 4"x5" electronic module that they are getting $850.00 for and send it to them and they rebuild it and upgrade it with a three year warranty for $150.00. Refer to the part number on Module master to see if they rebuild that particular module. They didn't list mine,but call them and they said they could. So next time I will know.

Sorry about that. It was www.gmpartsdirect.com, not automotiveforum.

Mine did the same. While I was deciding what to do, gmpartsdirect went from $488 to $509. I now have an '05 Yukon with a 6 year warranty.
