Well today brings the air conditioning on the ARC working but now my fan is doing what it was before. Running slow. About half speed when its turned up all the way.
I thought I had this fixed. The contact in the plug was loose and dirty so I cleaned it and away it went. That was the other day. It seems to have reverted back to slow motion.
I will get it out this week and clean the commutator and brushes and see what happens. I admagine that a bunch of dust from the brushes is stuck between the contacts on the commutator. The car does have 362000K on it.
