The generally accepted "fix" for the blower running constantly is the BCM (blower control module) on top of the evaporator case BUT I don't recall ever having anyone report the other related failures occurring simultaneously. I've never actually understood exactly what takes the BCM out, the couple times I've seen it, it just happens. Shut the car off walk away and wonder what the noise is.
You haven't mentioned anything other than just putting it away in that condition. Have you checked the related fuses? There's an in-line fuse near the blower that's often talked about but I've actually never seen it fail.
With the components you've mentioned down I'd check radio, CTSY, AC fuses in the panel and the in-line at/near the BCM. Unplug the 4 wire connector to the BCM first maybe, then check all of components again after confirming the fuses are good.
I assumed this is a C68 car.
I'd probably disconnect the negative cable for a while to let the CCM, the programmer and all of the electronics to reset themselves. This I believe would be right after confirming that the fuses are all good. Is anything on the AC control flashing indicating an error?
