Sounds like it could be a ground problem I looked real quick and didn't any common grounds. The main ground for the heater is on the backside of the block by the starter, the headlights is up under the dash on in the center on the drivers side. Take them both apart and make sure the connections & surfaces are clean and tight on the reinstall........

It's possible. Any where you get excessive resistance in a circuit will cause a voltage drop and give you electrical problems. If you aren't familiar with the process but have a volt meter, if you google voltage drop testing I'm sure you would get some good info.

Doing this kind of testing on the circuit when it's failing would help find the problem, if the grounds are good I would probably also be looking at the ign switch, they had their fair share of problems with those.........
