I hae a 94 Pickup truck 4x4 of course. 22re motor it didn't come with A\C factory but I heard that if <img src="/forums/images/graemlins/confused.gif" alt="" /> you get the parts from junk yard it isn't too hard to put in since the wiring and holes are there. What all would I need to get from the junkyard I need to make a list there is a guy bout 40 miles from here all he has is Toyota trucks should be able to get it all from him. Thanks for the input and helping a newb out. I really don't want to go another summer without A\C.

compressor, dryer, eveporator, ac switch for dash, High pressure and low pressure lines, condensor, ac idle up switch,seals. there's something I'm missing & I can't think what it is? If it's r12 freon forget it! If its 134 not a problem. R12 is very, very expensive!

DONT forget the evaporator drain tube,,,,,you dont want a puddle of water in your truck!!

April is here and it seems that I'm not the only one thinking (again) about A/C for my '84 SR5 extra cab. The biggest worry for me is that my copy of the factory manual doesn't show any wiring for A/C and since I have California emisions and have since installed a later model 49 state carbed motor (22R) I have a few extra wires in that area of the engine compartment.

I've had the dash completely out before to replace the heater core so I have no fears there. I just hope these 1984 trucks came with A/C wiring and that it doesn't have anything to do with that #@%$ California emissions engine computer.

I'm also wondering if I can use the A/C gear from an '85 - 88 fuel injected (22RE).

Any idea how the carbed motors idle up for A/C? Is it with a solenoid or vacuum switching valve (VSV) and dashpot that pushes the throttle up onto the fast idle step or is it some kind of air jet lets more air into the carb?
