1979 Chevrolet Pick UP choke lite comes on air goes off

I am the original owner and have been driving it since 1979. Just a straight six. Anyway just recentley a problem arose. Manual Transmission by the may. The problem is this. The choke lite comes on and the air conditioner stops. Then a little while later the the choke lite goes off and the air starts. I took the steering column off and checked the wire harnes for shorts. Unpluged the air from the fuse box. Followed all the wire to there respective place for both the choke and Air. Could find no problems but now the choke lite stays on and the air will not work. I am lost as to what to look at next. Does any one have any suggestions or run into this problem before? The air is not stock after market. By he way the truck runs fine with the choke lite on. I have also lloked at the carbuerator and the choke is not closed so I think it is some sort of electrical short but not sure.

I think the choke circuit contains other items, just don't know which. Check the continuity on the choke heater or just bypass it with a jumper to see what that does. The weather is warm now so you might not notice any performance difference. It may even run better when cold. Usually it's just the connection that gets oxidized anyway rather than the heater element burning up.

It sounds to me like a temperature sensor or a problem with the electric choke.

The only time I ever had that light come on was because I had no oil. I would check that first.
