If I understand your problem, what you actually hear is a "clicking" sound. If I am correct, your unit only blows out cold air. If so, your problem is the "Heating & AC blend door actuator. It is a small plastic box that contains plastic gears. The unit receives an electric signal to change positions, but the broken cogs prevent the unit from operating properly. A quick check to determine if this is your problem, turn the heater on. Adjust the temperature from heat to air. At some point the noise will stop.

2007 mountaineer with dual climate controls drivers side blows cold air passenger side will not. Any ideas?


There are doors in the duct work under the dash. These doors open and close to move between hot and cold, as well as to defrost, vent, floor, etc. These valves are operated by small electric motors. one of them is bad.

I had heat in the drivers side climate control but not the passenger, now i have no heat. It only blows cold air. My AC works perfect yet no heat.


Hi.in the dash there are flaps which control's hot or cold, those flaps break and then you will only have cold air blowing. You will have to remove the dash and renew those flaps

Driver side heat blows cool air passenger side blows hot air


Hello. The side that is not operating properly has a bad temp door actuator located up under the dash. I am assuming this vehicle has driver/passenger(dual)climate control heat and cold settings. This is a very common problem on these vehicles. Hope you find this information useful!

Its more then likely the temp door broken or temp door motor broken/stuck. There is 2-3 of these motors under the dash on the side of the evap/heater core box. Some require extensive labor to replace, good luck

Intermittant hot/cold air from heater


Had the same problem with my Mazda6 awhile back. Took it to the dealer and they found the radiator wasn't holding pressure. They replaced the whole radiator under warranty (WHEW!). Not sure how to check for that kind of thing, but it's a start.

2004 duramax dual climate control the driver side blows cold


Thankfully it was the drivers side controller! I found the temp control actuator located under the dash almost on the floor. I removed the four screws that held the cover in place then followed the wires to the actuator. removed the wiring harness then the two screws. replace with new part and heat works again!

A/C Heater problems


the main issue with this is either the thermostat or the climate control switch I do not know if your climate control switch is electronic or manual either way I would start out with the cheapest and go with the thermostat first good luck!
