It appears my aux fan has pooped out. The manual says, "check the supplementary fan for function, for this purpose pull the two flat plugs from the temperature switches ( 14 or 15) and connect to each other (connecting short)".
I reckon I should see if it will spin at all by doing this but I have no idea what switch they are speaking of. What historically fails on these? This is the first time ever I have had one fail. Is there a relay for this and, if there is, where is it? Donkey Shirts Bob Rentfro '77 300D 140K Litchfield Park, AZ
