2006 dodge ram diesel a/c clutch makes loud grinding niose

Other than making sure there is no air in the lines, (which shouldn't be if you haven't taken it off)
Sounds like you have yourself a faulty power steering pump.

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.

Most likely you have a leak. Turn the air conditioner on high and look at the compressor on the engine if it turns for a few seconds and turns off you may be low on freon. If it does not turn at all you may be very low on freon in both cases it needs to be recharged, you should also try to find the leak and repair it to. Also check the condenser in front of the radiator to make sure nothing is blocking it. Good luck with it.

The re-fill kit for the r-134 will only fit on one of the sides. You want to fill the low pressure side, but be sure you have a gauge not to overfill. he high pressure will be the larger side. But the gauge will only fit on one of the inlets for safety precautions.

Check the a/c clutch with the engine running and the airconditioner on first. If not then check the fuse/relay panel for a blown fuse or bad relay. If all of that is good then check the low pressure switch on passanger side of engine on top of the a/c line. Remove the pluf from switch and use a jumper wire to jump across the terminals in the plug. If the a/c clutch starts working then it is telling you the switch is either bad or you are low on freon. Check all connections on a/c system for any freon leaks. If you find any oily spots on the connections or around behind the clutch;you will need to have it repaired and recharged to correct the problem. Hope this will help you.

how to get the compressor to come on, to put freon in system on a 2006 5.9 cummins 2500 ram truck

you have what is known as an open diff. or worn out clutch packs in a limited slip. most makers put in a open diff because its cheaper and handles better. if you did not pay for it on your invoice your stuck with stock unless you put it in your self.
