Load placed on the engine takes place when the Compressor clutch engages. It will not engage if the system charge is too low on freon. It needs to be checked with a gauge, I think that may be your problem.

there is no relay in that box that is called the tipm or totally integrated power module. that module is controlled by a computer and should be checked with a scanner to see if you have a code for the a/c. i m having the same problem i have been told it could be low freon but can not get the clutch to engage to check the high and low pressure. Also read where it may be the diode in the clutch on the ac compressor if you have a multimeter probe the compressor a good compressor will read somewhere between 3.5 and 4.0 anything else and clutch needs to be replaced. other possibilities may be the high or low pressure switch on the line. on myh 2006 2500 diesel it is located near the plug for the compressor on bottom side of motor. hope this helps.

Check the low switch by the dryer or accumulator, its a long narrow cannister,
it will have a pressure switch attached to it or near it. put your, ac on high,
pull the molex off the switch and jump the molex with a wire or paperclip,
if the compressor comes on and the ac starts to cool, you will just need
to replace the low pressure switch, if the clutch does not come on,
check the low switch molex to see if there is 12vlts there. good luck!
