Would a code be thrown in the P38 before the blend motor fails? I have had a few probelems with my 2000 RR since i bought it. The most recent is the blend motor on the driver side failed. There has been clicking under the dash since i bought it 2 months ago. 2 weeks ago it started blowing just hot air & for some reason you cant turn the Heat/AC off at all. So now its 90 degrees in upstate NY & I have hot air blowing into the cabin. I dropped the truck off on Monday with an appointment to get fixed. Truck is still under warranty form when i purchased it. Here it is thursday & these shitheads havent even looked at it yet. The truck ghas been in there 2 different times for other bullshit. back to my original question. If theye have plugged it in on any of the times before, would it have thrown a code saying that somthing was wrong with the blend motors?
