ac switch

[Waterloo]

I would start with the actual ignition switch, where you stick the key in to start the truck. Is anything else still running like the radio, or anything that is getting power from the ignition side of the fuse block? Sounds like the ignition switch is bad. I had a similar issue, and I called the parts guy and asked him if there are issues with ignition switches in these ProStars, he told me they sell quite a few. I keep a spare.

Oh, if it is the switch, your old key barrel comes out of the faulty ignition switch and slides into the new switch, so you do not have to have new keys made. The switch will need to be drilled out of the dash, it is held in place with rivets, for security reasons.
