A/C clutch wont engage
 

My ac clutch was working a few weeks ago and sudden it stopped engaging. If I plug in Hp tuners I can get the clutch to engage, but the air still blows hot. I'm guessing my compressor is shot?

make sure compressor plug hasnt melted.
+1 to compressor

doesn't the system automatically stop letting the compressor engage if the pressure in the system drops below a certain threshold to avoid compressor damage?

I would check to make sure the system hasn't lost pressure before anything

:nod:

Could also be a bad pressure sensor.

You can jump out the low pressure switch (usually located near the accumulator) to see if the Comp. comes on . If it is blowing cold air it is most likely the switch. Good idea to throw some gauges on and check line pressures to confirm. Good Luck

Step One: Check the system pressures.
