Not shure what heating coil you are talking about but you could have a bad heater control valve,a plugged up heater core,or you could be very low on water.

My cold/hot knob on front dash clicks when i turn to hot


Look under the dash above the gas pedal and switch the hot to cold knob back and forth. you will see a cable hooked to a white plastic cam, this cable usually pops off the black plastic housing and causes this. If it is connected there it is in the control knob itself.

No heat / heater not working


not blowing air or when switch is on blows cold air when you have climate control knob turned over to heat? it could be a switch or blower motor or fuse if its not blowing any air. if its blows cold air when knob is on heat then is can be thermostat or low on coolant or it could be climate control module or it could be a air filter in dash.

A/C will suddenly send out heat. Fiddling with knobs seems to help. What's wrong?


You have a broken wire connection between the temperature control knob and the circuit board behind the center dash console. Vibration causes the failure and once the control knob gets loose the solder connection fails.

For someone that knows how to remove the dash unit and can re-solder a couple of new wires this fix should take no more than 1 hour. Make sure that you apply loctite to the heat control knob spindle nut when you re-assemble it.

The dealer quoted me 750 dollars to fix this issue and I found out that it's a common failure for this year. I fixed mine virtually for free but it took some tools and about an hour of my time.

Have you checked the coolant level? If it's low, it will result in diminished heat, and could be the problem.

Heat will not switch on


sound like a stuck blend door motor, not switching back and forth from hot to cold. the most likley cause is a bad heater control panel not commanding the motor to move as requested.
