Re: It Begins... AAW Classic in 72 Elky
I was able to get thru to Craig this morning and he cleared up a couple things. I found a switched connection with a heavy wire (power windows) in the accessories bundle to connect my AC to, It will run the fan motor and temp controls and of course trigger the AC compressor relay. I was able to get the Horn relay (too easy, just read the directions), fan relay (with a switch under the dash) and the AC compressor relay all wired and working. Put some freon in the system and it's blowing COLD. None of the wires seemed to get hot or even warm so I think I'm good.
The only other thing I would like to do is have the AC 'on' trigger the fan relay. I thought about using the compressor trigger wire, but then it might trigger the compressor when I flip the fan switch. Plus when it cycles off, the fan would also go off. I'll mull this one over, it's fine the way it is when I'm driving, but not if someone else is using the truck. I'm open to suggestions. BTW, this AC unit is likely a dealer installed under dash AC.
