I have a 2005 Quadsteer that has some wierd things going on with the HVAC. Two days ago I turned off the truck and the blower fan stayed running for about a minute afterwards. Later that day, I had it on A/C and it would blow hot air up thru the defrost. I was not able to change the temp of air or location from which it came. The next day, I got cold air again, but would only come up thru the defrost. The dash shows that it should be blowing out on the floor. The only thing that is consistant since the problem started is that the fan stays running for a while after I shut the truck off. Any Ideas?
