About a week ago I had an alert if "AC Off Due to High Engine Temp". The temperature gauge was at the minimum and seemed to not be reading at all. I reset the codes and after that everything seemed to be working fine. But today as the weather was warmer, I noticed the A/C wasn't working. I checked the fuse, and everything seemed to be in good order. Could this issue be related to the "High Temp" message or is it more likely the AC/ just needs a Freon recharge?

Hi,

The idea that the high temperature was indicated is what likely caused the A/C to stop working. If the computer thinks the engine is overheating, it will cut the A/C to eliminate the added load on the engine and hopefully help cool the engine.

Now, when you say the temperature light was on cold (minimum), did it start working eventually? If not, check to make sure the sensor (located at the side of the radiator) is connected and there is no damage to the connector or wiring.

Note: There are two coolant temperature sensors for this vehicle. One is for the temperature gauge (mounted to the radiator), and one is used by the computer for the engine. The one for the computer is mounted on the thermostat housing. I attached pics below to help you locate them.

When the engine is cold, check to make sure nothing has come apart at either of them. Also, confirm the coolant is clean and full.

Let me know.

Joe
