2004 Silverado intermittent heat
I have a 2004 Silverado LT Quadra steer. Resently, I have noticed that cold air is blowing out of the ducts even though I have the temp controls turned up. The engine temp is up to normal. I have also noticed that the temp increases 20-30 degrees and if I rev the engine, the gauge drops to normal and I get heat. Could this be a thermostat problem, Water pump problem, blend doors, etc?<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com
