Help!!! It figures that were are finally seeing winter weather and my heater doesn't work. I turn my car on and the heater does not come on. The readout shows what temperature I want but the fan does not come on. Manual or auto - neither works. Any suggestions?

 

blower motor resistor under the dash near the blower motor about 100 bucks for the part

 

Hi, do you know why my wifes 1999 300m heater works good when driving but when you stop at a light the air changes from hot to cold in about 10 seconds

 

forgot,, i can hear a ticking sound coming from the ac heat controls when the cars off and the keys are out

 

well the heat issue is low coolant more then likely a heater core leak i had one in my Concorde same body style.
The clicking could be the doors just going to rest when u turn the key off is that the only time it does it or all the time when the key is out?
I live in ATL if u want it looked at i do side jobs.

 

Help, we have no heat!!! Coolant level is fine, controls all seem to work, blower works, but all we get is cold air. Any ideas?

 

air in coolant system or low coolant
