I have a 1999 Dodge Ram 1500 Sport and the AC is not working and I was doing some research and I noticed the center of the ac compressor is not turning when the ac is turned on. Is there any fuses or relays I can check before I go any further trying to figure out this problem.

You can check the fuses but if the system pressure isnt high enough the compressor wont turn on. You need to check the actual system pressure.

Check fuse # 5, underhood power distribution center and the compressor clutch relay.

Apply battery voltage to the compressor clutch terminal to see if the compressor clicks.
