Tpi sensor is bad, or perhaps you have a bad connection. if you change the sensor or computer board that should take care of your problem. kind of expensive but not to bad.

My 2004 Sebring heater only blows warm air when the car is moving. If I stop at a traffic light or put it in park it blows cold air. Any ideas?


1st check the coolant level. If it's low, what you describe will happen. If level is ok, let me know, and include info on engine temp gauge--how long to warm up, is gauge at warm up low temp range, normal, or hot?

Check coolant level. Check for heat at the heater hose going from water pump to heater core at firewall. Check to see that cable is moving coolant control valve from the closed to open position. Low mileage so it shouldn't be plugged heater core.

Is this a gas or diesel? Usually this is to protect an engine if there is a fault found by the truck's computer. It can be related to oil level, temp, or pressure. Could be related to the antifreeze. Check the levels. Also you said something about a headlight being dim. So You will need to check that Curcuit out as well. Could be related but a scan-tool would be needed to look a parameters.

My 1990 gmc sierra 1500 temp. guage stuck after new thermostat.


Hi

Does your temp guage needle drop to Zero when you switch off ignition ?

If not, your temperature transmitter is faulty, or the wire running to it is earthing out somewhere.

Hope this is of help.

Good Luck !

John.
