The ac and ambient light of 2011 ford edge goes on and off intermittently,and also when u switch on the auto climate u can't switch it back off until u off ac completely.

Make sure that your battery connections are clean on contact surfaces and properly tightened. Check to make sure your battery has 12v or better in it.If not, have it charged and load tested.

Same car, same problem. Press MODE, FRONT and REAR buttons together to reset tempreture. You probably need to replace the sensor GM part number 15047946 it is in the front grill email me for a picture. [email protected]

You should make sure you have proper charge for sure.has your battery gone dead lately? I know on some of them digital climate controls will act exactly like this and have to be reset or go through a setup sequence.

Not sure on your car, but the owners manual does .most ford cars have the rest switch on the passenger side above the kick panel or towards the center

There's a feed from the engine coolant temperature sensor into the AC controller as if the controller thinks the engine is overheating it'll shut down the AC to reduce the load on the cooling system

Try unplugging the cooling sensor on the engine ( follow the radiator top hose back to the engine as the sensor is close to this) and see if this replicates the problem, if it does then you know thats the issue.so the coolant temperature sensor needs to be replaced.

-------------- Also the possibility is faulty evaporator temp sensor.It may be sending a false signal to the climate control module that the evap is around freezing temperature thus shutting down the compressor. The evaporator temp sensor is located on the evaporator housing, in the a/c system, and monitors the temp to prevent the evaporator from freezing up. If the AC control module sees the temp going too low, it will send a communication message to the pcm to turn off the a/c compressor until the evap temp returns to an acceptable range. The other possibility is the high pressure switch located on the line in the right hand side whell arch. Why I mentioned the high pressure switch because as the temp increases the pressure in the system increases and if the ECU sees this signal from that pressure switch in the wheel well on the a/c line it will shut down the compressor. You can test this with a digital voltmeter or install a set of gauges to the high and low side service ports and see where the pressure go. It also may be the temp sensor element on the compressor itself. ----------- This should help.Thanks.Helpmech.
