1973 challenger AC not working

[CudaK]

Hey,
Just took the challenger out for a run and went to turn on the AC and the AC will not come on... it HAS been restored.

Came home popped the hood and the compressor is not cycling. I pulled the wire and checked the clutch, ran power to it and the magnet works... CLICK CLICK CLICK.

Checked the fuse and all the cables and they work fine, heater control valve is new and works fine.

Will low refrigerent cause the compressor not to engage ?

Anything else to check, worked awesome last summer...

Thanks for your time.

yes ,if it leaked out it will not come on.

The drier has a pressure switch. You could try to jump those and see if the compressor engages. If you have low pressure you have a leak somewhere.

Did you have the stock system rebuilt or is it aftermarket ?

Ok makes sense I will do that and know for sure.
