2003 Yukon XL. I was told I cannot do an alignment on my vehicle unless I change the power steering box. The front wheels tilt inward... can the tilt be caused by a bad steering gear box? 2 Answers

I have a 2002 Yukon XL. The heat works in the rear cab, but blows cold in the front. What's wrong with it? 5 Answers

My front heater has just stopped working. I've checked the antifreeze, filled it, and still cold air. The rear cab vents blow heat just fine. What could my next step be to have checked?
