Ford flex passenger warm air with AC on
When I turn the air on driver side works perfectly fine but
passenger side kicks out warm air. Any suggestions please
The ductwork has blend doors that move to get the temperature to the vent where you want it. Could be that one of the blend doors is sticking because the door actuator is defective. You may have noticed a tapping sound under the dash from a defective actuator. The doors are located under the dash and possibly behind the glove box; the actuators are small boxes. Try a spray lubricant on the actuators, or remove them to see if there's a broken sprocket. Might need replacing. It's not a difficult fix.
It never made the ticking noise so could it have just went out completely
I said, you may have noticed a tapping sound. So, the broken sprocket isn't moving.
