AC fail/light flashing

[BG1988]

lmfao.... welcome to ‘brents world’

To test, turn the AC on. Press and hold the AC & recirculate button button at the same time for 5 to 8 seconds.

The A/C light is designed to flash and disallow A/C operation if any of the following conditions are present:

so you meet one of the requirements below

Ambient air temperature (AAT) is too cold (35 degrees or colder)
Vehicle system voltage is less than 9.5 volts
Refrigerant pressure is too low
Refrigerant pressure is too high
Engine coolant temperature (ECT) is too high
Engine is not in RUN
HVAC Control Head is in the OFF position

I seem to have it fixed now. The relay was not making a good connection on not turning on the compressor. It was in need of a recharge also.

Where is this relay?

It was in the engine area, the underhood fuse box.

thank you. I’m having the same problem all of a sudden. Hopefully this’ll fix it.

I did also replace the ambient air temp sensor. Problem persisted but many resources thought that might fix it too.
