Here's the answer to my problem as explained to me by my mechanic. The multi-function switch that sits in the steering column controls the turn signals, hi/low beams, wiper/washer and cruise control. When you switch between high and low beam one circuit opens, the other circuit closes. The fault occurred on the low beam side and would not ground when I switched back to low beams from high. My mechanic was able to fix the ground problem by cutting the ground wire that ran from each headlamp back to the multi-function switch and grounded them directly to the frame. No doubt GM wouldn't approve of this fix but I wasn't about to pay $250+ for a new switch plus labor.

We have had this same issue on our 2004 since about 20,000 miles now we have 47,000, finally got GMC involved after many times of taking it into the dealership. Last week they replaced a wheel sensor, but now we are getting all sorts of messages coming up like the ABS light, Service Stability and the traction control off light comes on. Anybody else have these same issues?

Battery drain caused by new pump for autoride system staying on even when key removed. Checked relay - works fine. Now looking for diagnostic on controller. Bypassed system and pump works fine with shock leveling on demand.
Anybody got any suggestions other than Mr. Gut Wrench?

GM is now offering a whopping $8000. instant rebate and ZERO percent financing on new Yukons. Sounds good? Think again. GM has reduced the value of your SUV by at least $8000. or more. They have also severely reduced the public's perceived value of their product. GM products are being seen as shoddy and value challenged. GM is deliberately canabilizing their own customer base and destroying resale value of all GM products. All GM vehicle owners are losers now since your auto investment has fizzled. This is how GM is going to run their business even after the morons in congress give 15 BILLION dollars to this out of control auto company. GM does not have a clue but they know how to hurt their customers big time.
Make sure you patronize GM because they don't give a damn about YOU.

Did you ever find out what was causing the traction activation issue? I have the same issue, driving down interstate, traction light came on, reduced engine power?

found it out. the accelerator pedal position sensor had a bad connection. i unpluged it and plugged it back in and truck runs just like new. also got error code p2138 just in case it happens again save ur money and look for loose connections on any wire connection. GOOD LUCK. im glad i had friends in good places.
