Air conditioner issues

[abrookey]

I have a 2010 Ram, very basic truck, 5.7...out of the blue the air conditioner started blowing warm air. Can turn the clutch by hand, just not engaging. So far I have replaced the sensor on the high/low tube [forget which one]. replaced the switch controls on the dash, checked all the fuses under the hood [was told the clutch is a 10 amp], pulled the pigtail off, hooked a jumper wire + and - to the battery, it then engages. Is the 10 amp fuse I was told correct, or am I looking at the wrong one??? Many thanks in advance

Just curious if you’ve checked to see if there is a referigerant leak. There is a pressure switch that won’t let the compressor run if it’s too low on referigerant.

Have ya hooked it up to a set of gauges and checked the pressure? system may be low. Also if you have re charged it did you pull a vacuum first?
