Where is the ac relay located on a 1994 ram van 3500?

SOURCE: Dodge Ram AC not blowing cold

By pass both pressure switches one at a time with small wire or a paper clip. If comperssor kicks on replace the swich that you bypassed.
if not it could be the fan clutch ot the compressor. Compressor runs about $400.00

SOURCE: Heater and a/c controls on my 1996 Dodge Ram Van 3500

There's a large black ball or bullet shaped black plastic cylinder called a vacuum collector under the hood. Check to make sure this is leak proof. to do so just run the motor/engine for a few minutes and pull one of the vacuum lines off from it. yuo should get a long hissing sound. If not relace the two vacuum lines. If you do hear the sound then....it gets a little tricky. BEHIND the climate control unit is a vacuum harness with several different colored lines all held together at the connection end. If you can get at this, pull radio, pull ashtray assy, you may find that it has slipped off the control unit. Check these steps in the order that I've given, it will save you alot of headaches. It might boil down to needing a new/ used climate con trol center. Thanks and good luck, Dana

Hi:
The easiest method to do this is to go to an auto parts store and buy a belt designed for a truck with no air conditioning. The belt will be the right size, and you just install it as normal, and bypass the compressor

First thing is to look at the a/c fuse and relay under the hood in the power panel. Possible blown fuse or a bad relay. If no blown fuse or bad relay found then go to passanger side of truck and you will see a black canaster with a low pressure switch on it. Remove plug to switch and using a jumper wire jump out the plug to see if the compressor clutch comes in. (have the truck running with the a/c selector switch on ). If the clutch comes on then it's either you have very little freon gas in system or the low pressure switch is bad and will need to replace it. Use small pliers to remove switch and replace it with a new switch, make sure it has a new o-ring inside switch before installing it. Hope this will help you.
