WTF... I just found out that the blower wasnt working because of the black box that you hook up to the back of the controller...
But now it all works except the a/c switch light will come on and blow cold for a fue sec then dim out and stop the cold....
What can it be???

 

2nd gen rx7's in general were known for bad A/c logicons its a possibility that you need another one.. not sure who but there's someone on the forums that rebuilds them think its Pele?

do I have to have compressor for it to work?

 

NVM but i dont think the compressor is hooked up.... bout to get some pic of it...
I have to take the hole dash off to pull the 17 pin logic as far as i can see... idk where it runs to.. probably the main harnus.
looking though http://www.cochran-racing.com/FSM/s5...AC_systems.pdf
to try and get and idea what what to check out..
i have two more logics that i can try out... said they worked but idk....

 

No no no... pull the "defroster" vent off the top of the dash... up by the windshield. The logicon connector unplugs from the body harness underneath there. Tie that harness off with a piece of string after you disconnect it so it's easy to plug back in and doesn't get lost in the dash. Other than that, remove the dash plastic, then four phillips screws on the front of the Logicon, and disconnect two connectors from the Logicon and you're ready to remove it.
