Got my 83 with many electrical problems (some of them seem to be fixing themselves) just last week the blower had quit working altogether.

Found that the defrost relay had a bad pin looked kinda scorched, and the fresh air blower relay was not turning on. I confirmed the blower and resistor pack was working by measuring the resistance from relay to ground with the different switch positions. Also checked power at the relay
For now I have swapped the good relay to the defrost so I can have something for if it gets too cold, I'm now trying do figure out how I can get to the control unit and why it's not turning the fan on. Are there common failure points other than the resistor pack?
