Hi all,
Yesterday was a warm day, and our AC was working great. Today we loaded into the truck for the first time since late last night, and no AC at all.
This spring I had to have the refrigerant recharged, but since it was working well yesterday, I don't think it's so low that it won't work at all. But hey, I'm no mechanic, so maybe I'm way off base.
In any case, the compressor isn't engaging at all. I can watch the pulley and nothing is happening. I know it can be anything between the computer and the AC, but I don't have the tools or the pin-outs on the AC relay (5L3T-AA) to test the relay or the fuse block to see if the computer is sending a signal at all.
I was wondering what you, the experts, would do in this situation? Does anyone have a diagram of the relay pin-out so I know what or how to test it?
Also, I have a question about removing the compressor clutch assuming that the electricals prove to be sound. When I turn the bolt in the clutch, the compressor just turns over. Is there a special tool for holding the pulley fixed while you turn the bolt or is there more of a "trick" to it?
Thanks,
SH
