Question about 2002 GMC Yukon XL

2002 Yukon XL

We replaced the ABS module and when doing it there was spark from the battery. ABS is working fine. Problem now is the climate control. If you turn the fan on auto at 68 you get hot heat and have to keep it turned to 82 and off and still feel hot air coming thru the vents. Have removed and waited a few mintues with several diffent fuses related to climate control in the electrical center. Got any suggestions?

Sounds like maybe something got messed up in the onboard computer. My suggestion is to take it to a local NAPA, AutoZone, Checker or similar store and have them hook a device up to the computer and see what error codes are displayed. After doing this, they should be able to tell you what the codes mean or just post them here and I would be happy to let you know.

good luck and feel free to let me know of any other questions that you may have, just ask

C0550 is the code for the ABS module. It is on the frame under the vehicle around the drivers door area. It is a module with all the brake lines coming from it. Reset the trouble codes and see if the problem returns. If it does, the module is not serviceable and will need to be replaced.

Could be that the switch itself is shorting and allowing power to flow,if you can get to the switch I would use a voltmeter and see if there is voltage on the output side with the switch off.

Abs system keeps running even when you cut the truck off.

Common problem in GM's. Had it happen in my 2001 Tahoe. There is a company in Russia, IA who rebuilds the module for less than $200 and gives a 5 year warranty. Cheaper and better than you can get from GM.

Go to E-Bay and do a search on ABS module and you can then find their website for full instructions and details about this modification. I did it, and am well pleased with their work.

The dealer will charge you $1300 - $2000. Contact Module Masters. They are great to deal with. You have to ship it to Moscow, Idaho. It cost me about $15 to ship it (with box, packing, and insurance at a UPS store). They charged me $130 to rebuild it and gave me a 5 year warranty. It cost $8 to ship it back. To in total, it cost me $153....totally turn-key.
