Air Conditioner not blowing cold after freezing temperatures?

Hi,

When temperatures get below 39 degrees F, the compressor shouldn't turn on. So, the cold temps shouldn't have hurt anything.

As far as the new issue, we need to determine if the compressor is engaging when you request the A/C or defroster. If possible, have a helper start the engine and select A/C. At the same time, watch under the hood for the compressor to engage. In addition to seeing the clutch engage, you should hear a click sound when it engages and one when it disengages.

Try this and let me know what you find.

Take care,

Joe

Thanks for the insight. I have determined the A/C clutch is not engaging when turning on the AC/Defrost.

Hi,

Could you let me know if this has automatic climate control or if it is a manually controlled system? I found different wiring schematics based on that info.

Thanks,

Joe

I believe it is a manually controlled system.

Hi,

Thanks for the info. Take a look at pic 1 below. I need you to check both highlighted fuses first, in addition to checking the fuses, confirm there is power to and from them.

If they check good, switch the compressor relay with a different one in the fuse box having the same part number. If there isn't one, here is a link that explains how to check the relay and circuit:

Let me know what you find.
