It has codes! scan it again these engine are always doing something.."No codes no check engine light.Ones give a code for rich on bank 1 or 2."? seems like a code what ever, The Check engine light doesn't have to be ON read the Data off the computer and its and easy fix. Check the long term and short term /fuel trims and throttle body. You REALLY, haven't found a mechanic yet. This stuff is so easy. Regards

I have a 2006 GMC Yukon XL with a dual zone ac/havc unit. The rear heat works but the front only blows cold air. I have checked all relevant fuses, checked the climate control module, and all are good 1 answer

The heater core is good, I believe, since the rear is producing heat. Could I have a bad actuator? And if so, how can I diagnose that?
