Hi, new to this forum, hope one of you guys can help me. When I turn off the ignition, the lights, heater, and radio come on and won't shut off. The door locks won't operate correctly either, the driver side lock will not stay down. When the the van is running, everything operates normally. I swapped the relays and tried a new ignition switch, but that didn't help. Any suggestions before I take it to a dealer? Does the front ECM control any of this?
