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.

Need help.. I have a 2001 Dodge Ram 1/2 ton truck.. heater will not get hot.. changed the thermostat..had the radiator flushed.. checked heater coil (sp).. checked the air conditioner flapper door to see...


1 check,Feel the heater hoses,do they get hot ,both or one?They should be hot,if not flush the heater core directly with a hose,back and forth at each hose connection.
2nd check,clamp off the top rad hose and force the hot water through the heater and check heat output.If there is heat with top rad hose clamped change the thermostat,it's either leaking or defective,new or not.

Front blower motor town country intermitantly stops working. Rear blower works fine.


Most likely the motor is going bad, but it could be the switch. If fiddling with the switch will make it work sometimes, replace the control panel. Otherwise, replace the motor.

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.
