Thanks Gilly.

I'm trying to squeeze a few hours of diagnostic into the weekend. Sombody stop me if you have the answer or I'm headed down a dead-end path.

I'll check for 12V at the fuses. If it is not there I'm jumping it in.

If I've got 12V I'm going to uncover the blower motor / power control module and see if I can reverse-engineer the power and control signals. Apparently there is a control voltage (something like 0.8 to 9V) that sets the blower speed.

I figure that there can't be that many wires just to control the blower. I'm guessing 2 big ones for power and a few smaller ones like control voltage in, maybe on/off and possibly a velocity feedback.

I'll record my efforts for the benefit of others.

Regards,

Barry
