Maybe I will get better feedback. 88 Camaro sports coupe. Did some one try to change my car over to an AC car? The heater controls have a AC select on it. But nothing is hooked up right. I've taken the box and fan off. Got the none factory wiring out. One question I have is, what all is there supposed to be. I see a vacuum controlled valve inside the dash. There are 3 cables. 1 controls the heater core door. Another operates the fan door. The 3rd must do the defrost? The vacuum valve looks to be over that. I will have to take the whole dash assembly off to find out if nobody on tgo knows.

 

Here are some pics.

ARA was an aftermarket manufacturer of a/c systems. When I worked at a Chevy dealer, we sent MANY an S-10 stripper (4 cyl, 5 speed, no rear bumper, no radio, no a/c) to a local A/C shop to have ARA air added. It was cheaper than ordering the factory system, and gave the dealer an option of having 30 stripper cost-leader pickups on the lot, that could be fixed up if the owner wanted. Stereos, stripes, bumpers, and A/C were all popular upgrades.

Looks like this car started life without A/C, and someone had it added at some point.

Is the Service Part ID (SPID) label still with the car?

 

Yes spid still there. Some codes a little hard to make out. What's the stock non AC box look like? I run the rpo's and alot of them came up blank.

 

Only 39 codes. Aar,c41,d15,d60,d81,d88,e5z, e7z,e9z,gu2,j50,k99,l03,md8,mxo,na5,nk3,n90, p84,qxz,um7,uqi,u79,van,v73,ww2,w62,1ay,1sa, 16p,41u,6xu,7xu,8ux,9xu,86a,827,82b.829. best I could tell,thats what they looked like. One of the previous owner tried to fix the fan switch or something. Drilled holes in the firewall and didn't seal the hole. spliced in about 20 wires and Nd connectors

 

Looks like the ara tag has a manufacturer date of 8195

 

On my '88 T/A, A/C is RPO C60 as I understand it.

Ugh!
