my 90 4x4,heater control panel won't regulate to the floor,jUst to the dash and defrost positions, and now I can't get the hot air,with out disconnecting the battery for a time, and then after a short time or in between shutting the engine off and starting it again,it falls to deliver hot air
again,I've had the flap control motors action visible on the drivers side goes from defrost to dash but in between this motion it throws air out to the floor but not stopping at the floor position,I read one article where the ground wire is some how connected to the parking lights,also thinking that I could splice into the grd. side of the circuit:nonod: and make a new ground connection, any body got a wiring diagram for 90's chevy{ Where can I find a schematic and or wiring diagram that would give me the location of the ground wire in the loom or plug for A/C heater control panel ?}I NEED THIS RESOLVED!!!!:mad2::skep:
