I’ve got two issues with the dashboard in my 2003 Yukon XL. One is electrical and the other is air conditioning or HVAC in general. I’m hoping someboody here has had one or both of these same experiences so my fingers are crossed!
Electrical: At times with no relation that I can track, the entire dash goes dark. When this happens the radio is out as well. I can be in the car driving and all is well. Go to the store, come back out, stick the key in the ignition and all is dark. Sometimes I can turn the key off and back on and it will light up, other times this does nothing but a few bumps down the road will light it up. Obviously this is an electrical connection and I would think a major one since the entire dash goes out. Exterior lights are not affected. While I’m at it, unrelated to this is the temp/compass in the rear view mirror. This has gone out altogether. Any ideas for this too?
HVAC: At least when the air conditioning is turned on, there is a ratcheting sound that comes from what sounds like something in the air duct above the driver’s feet. This happens every time now. Just the other day the ratcheting sound started and stopped by itself during normal driving with nobody touching a thing but this is new. The vent, air conditioning and heat all work fine with the dual climate control, it’s just the nasty noise at the beginning. Any ideas?
If it matters, this is a 2WD SLT with the 5.3L. I searched a little but didn’t find what I was looking for. New to this site so I may be missing something. Thanks a bunch in advance.
