I've tried every thing to get my heater to work but the thermostat could that also be a reason for no heat?


Asked by Nov 08, 2013 at 06:53 PM about the 1998 Chevrolet Blazer 4 Door LT 4WD

Question type: Maintenance & Repair

1 Answer


Yes, the thermostat could be stuck open. Look at your temperature gauge. After about 15 or so minutes of driving it should be one or two notches to the left of center (210°F). If it's considerably lower or doesn't move at all it's a good bet the thermostat is stuck open (overcooling). HTH. -Jim
