A buddy has a 2002 chev x-cab 4x4 silverado. the windows fogg up bad. He is not loosing coolant so I don't think its the heater core. What else might it be?

Replying to: wakejunkie360 (Nov 24, 2008 4:06 pm) I just bought a 2004 GMC Sierra SLT with dual heater/AC controls. The heater blows hot when set at 32 C which is full heat setting. Turn it down to 31 after the cab heats up and only cold air comes. Any setting other than full {32C} gives cold air. I have seen this come up in this forum a few times, but never finding an answer.My local mechanic did a flash but still didn't help. Replies to this message: cloveless (Nov 23, 2009 6:24 pm)

Replying to: rfb1955 (Nov 22, 2009 5:40 pm) I had a similar trouble. It would only blow hot air out of the defroster. I tried to "flash" it a few times by unhooking the negative post on the battery and it did nothing. I took it to the dealer and they re-programed the computer. The service guy said it would not come out of full blower and that would be really expensive to fix. I started it up and it has worked beautifully since. If the computer isn't fried, seems as though re-setting or re-programing the computer is sometimes a fix.
