I have a 92 and 95 diesels with no power to the climate contol board, hence no blower. Fuses check out ok. Any ideas?

Recheck fuse 7..test both sides of the holder [ not fuse ends] with a 12v test lamp.....................

Today the fuses are all good, power to the climate control. If I jumper a motor switch contact to ground I believe I can hear a relay and the faint sound of a motor turning.

I haven't the foggiest. Next three numbers for both are '584', not what you need. Pick one and I'll try and match it up.

Boo -Yaaa....that was easy. OK You have chassis 124.128 behind the brake booster is a 3 prong plug. Red/Yl/Blk W/Key ON, CP on Defrost and Fan sw on High, take a Voltage test from Red to Blk..should have 12v If NO, then check fuse link at shock tower. If yes, then take V reading at Yl to Blk..should have 2-8 V..if No, CP is not giving signal, if yes , regulator or blower are bad.

ok, both vehicles have 12v red to black, 5-11v red to yellow. Is there a check for the regulator? Thanks.

Anyway, if that test OK, then you have to get to the motor/reg and ground the Blu wire that goes from the motor to the reg....that will give you high fan, verifying fan motor. If yes, then reg is bad. The yellow wire is the trigger voltage to turn on the reg, which is why I have you verify voltage at yl wire before going down to the motor. When you ground the blu wire , it is the same as direct 12 v to the motor b/c you have 12V + at the red and the blu is the ground side of the motor circuit. The regulator simply controls the ground side of the circuit [ a switched ground]
