I have an 01 4x4 ST, 122,000 on it and my heat only works when I am accelerating. When I am idling it will just blow cold air. Ive had the problem for years now but it never bothered me to much to do anything about it. Im in NC so winter isn't so bad.
I have looked all over the internet and after talking with some friends think that it could be a vacuum leak. Looking at all of my hoses, everything seems okay (given I couldn't really see the bottom of any hose). Any common vacuum leaks for an 01 or other ideas?
It is NOT coolant level, air in the cooling system, thermostat, and I wouldn't think heater core because I still have heat, but only when pressing on the gas. Thanks for any help!
