I purchased my 1970 Challenger in 2009. It sat 20 years in AZ desert before I got it. Yesterday I finally got to make some noise with it. It starts and runs fine. I put a 440 with 727 in it. I replaced the engine wire harness. I installed electronic ignition. I have a weird problem. The only time the ignition switch works is if I push any of the buttons on the AC/Heater control. If I push the off button, the ignition does not work. I have traced wires, everything looks really good under the dash. I don't see anything that has been spliced or messed with. Any ideas? Thanks.

cool anti theft feature !! I assume the power is interrupted somehow feeding the ignition switch but throught the A/C controls makes no sense to me

Sounds like the ignition power source wire is somehow being powered up by the blower motor circuit. Disconnect all the wires to the ignition, a/c controller. Check the connections with a test light, Volt/Ohm meter or whatever you have on hand. Check wiring to fuse box. Some thing is shorting or connected incorrectly.

I think the neutral safety switch and the blower are on the same bulkhead connector. I will check there first then unhook everything like you are saying. Thanks.
