Customer Question

I have a 2013 Lincoln MKX with 113K miles on it. I purchased it new in 2013 & drive a LOT as a real estate agent (hence the high mileage). I have had many issues with the vehicle since crossing over the 100K milestone....but the newest one has me more worried than ever. This morning.....out of the blue.....the A/C on the left (driver's) side of the car stopped working. It only blew HOT air.......and the A/C on the right side of the car was working like a champ. What could be causing this?

When the temp output is only correct on one side of the dash, this will be due to a faulty Blend Door Actuator, Actuator Linkage or a door internal of the HVAC housing. More commonly, the actuator or linkage. The driver's side actuator is located behind the center/driver's side of the dash (just above and to the right of the accelerator pedal). Inspect the electrical connector and wire harness for any loose, broken or damaged wires. Inspect the linkage for any broken, misaligned or disconnected parts. If these check ok, remove the actuator and move the linakge by hand. The temp should now be correct. If not, the problem lies internal of the HVAC housing. It will need to be removed and repaired as needed. If everything checks ok, replace the actuator.
