Looks like the Aux water pump is working(leaking), so it looks like the problems are coming from the AC Servo now. When I select defrost, it's not blowing out hot air, just warmer air so this is telling me that I am having a problem somewhere. I also checked the temp sensor in the dash and cleaned it off, and the coating that is on it is cracking off, so does this mean that the part is bad and might be causing part of my problems???
