Default Ac not cooling

So ac is blowing but not cool. System is charged with refrigerant, when I hit the button to turn the compressor on, it dosent light up, is there a fuse I should check for? Is there a sensor I can check? How can I tell if the compressor is bad. Thanks

What does the exterior temp show on the dash?? If that sensor is bad it affects the operation of the AC.
I will check when I get home as I do not daily drive it

Default Ac

Crazy idea. But my ac was workinh fine. I had a coolant leak. Pressure was not as its suppose to be. I lost my ac. Once i replaced the reservoir the ac started working again. Like i said. It sounds crazy but i have no idea if the pressure or leak affects the ac. Someone correct me please.

I know there is freon in the system, but I don't hear the compressor, is there a way to directly jump the compressor so I can make sure it's not bad, can I just apply 12v to input or is there a special way to jump it

JMHO
I used it for the same reason on my vette and thought it was very easy to follow, yet as a experienced mech sometimes I take a lot for granted !!!!! Thanks Chuck !!!

Is there an outer temp sensor with the manual ac? Is there a way look at it from dic? I checked the fuse and relay and they were fine.
