Alright. The heater controls are being very finicky. Some of the display lights don't light up and when I tap that face plate they begin working for awhile. Now the recirculate air button doesnt work, but all the other ones do. Could this be do to a faulty heater control unit, or maybe the unit isn't getting enough power to operate properly. When I turn on the headlights the cabin lights dim, would this have something to do with it? Is my voltage regulator on the fritz, or maybe the battery isn't supplying enough voltage? I dont want to go to a salvage yard just yet for a new control unit.
