Question about Buick Cars & Trucks
Heater or a/c not working in my 1999 Buick. Shows different temp readings and have to turn the heater temp up to about 99 F to get heat but won't shut off without lowering the control. No heat or a/c and have been told it may need to be recalibrated. Vehicle had had some repairs just previous to this problem but the repairs had nothing to do with heater or a/c. Is calibration a possibility? Otherwise, what?

SOURCE: heater valve
there is no heater control valve in this truck, heat control is done through what are called blend doors. So the issue may be the front blend door motor has failed, this is very common on all Ford heatimng systems except the Focus.

Check water pump and make sure that its working. Should be circulating antifreeze in radiator and in engine. You can also check and the head gasket and make sure its NOT blown. Good luck and thanks for using FIX YA

The security system (VATS/PassKey) is faulty. You can find a great write-up here: http://newrockies.ca , it was the only thing that saved my Park Avenue.
