1) The heater issue sounds like a vacuum issue. It sounds like you done have adequate vacuum to operate the vents at idle speed. I don't have the expertiese to tell you where to look or how to diagnose, but look in other forums for similar complaints and see what other people have to say.
2) There is nothing feeding the radio except 12 volts.
Buy a new radio.
3) Do I read this right, you have electric door locks and they used to work but not anymore?
Frist, do they make any sound when you try to lock/unlock them? If so you have a linkage problem. Open the door panel and look.
Second, if there is no sound, then check the fuses. Some cars have 2 fuse boxes. One is inside the car and one will be under the hood. If all fuses check out. Check you door switch.

Check these things out and get back to the forum.
