How do you change the thermostat in a 2003 Venture?
The heater blows warm air but not as hot as it used to be. The fluids are full and everything else seems to be ok. Could it be the thermostat?
Revmom, your best bet would be to go to your local library and get the chilton manual for your Venture. It will have the answer to every question you would ever want to ask.
