Re: Replaced heater core, now electrical problems.
Still working on this. I sent it home with the guy to be brought back today. I found some more clues: along with the power outlet and cigar lighter not working, heater blower not working and power door locks not working, one weird thing, the light for the HVAC controls comes on when the headlight switch is off. It turns off when you turn the lights on. Opposite of how it should work. I have checked the grounds behind both kick panels and every connector I can find seems ok. I found a wiring diagram but I can't decipher the dang thing. There has to be some common point for all these circuits, I just can't put the pieces together.
I can confirm that relay for the blower motor is working as it should and also the relay for the door locks.
