    Afternoon everyone,

    My 92 Burb had a heater problem about 2 years ago, that fixed itself until about 2 weeks ago... (dead, no lights period).

    After some diagnostics, the thing I noticed, was that at night, there would be lights, as long as I did NOT turn the headlights (or park) on.

    So I traced the ground wire for the heater controls (pin 8 (top is letters, bottom is numbers), Pin 8, in the connector, did a test ground with a pick and a jumper wire, "TA-DA". works fine, added a ground wire to firewall, been working correctly since....

    Thought someone out there might want to know this.....
