Question about 2008 Ford Expedition El
Not responding shows on control but not doing anything sometimes stars working on own
I will try to answer and offer you a couple of choices based on 2 different potential problems.
The blower motor resistor is the control for both the heater fan blower and the A/C since they are the same blower motor. It is the boost that you need to feel either heat or A/C through the vents. The part can be traced from the heater blower wires under the hood to a control about the middle of the Firewall. 2 bolts hold it in place with 1 connector wire. But a heater line will likely block access to switching the part. It is often a part that tapping will start it working again.
Another A/C intermittent problem is low Freon. A certain pressure will engage the A/C compressor switch. Since outside air temperature can boost the internal pressure remaining in your A/C system, every time it expands the Freon; your system may work.

It will be a cable that will be disconnected. or broken. Youll have to take some of the dash apart to see the cable and follow it to the switch. Dont be affraid to take some things apart and when you cant see, use a mirror to help you see behind the dash. work the control and watch the action. You will fix this dont get frustrated. good luck
