I have an 83' 300D that keeps blowing the blower motor fuse out whenever I put on anything but outside air. I.E. Defroster/A/C/Heat. It will run for about a minute or so than blow. It will not blow if I only use the outside air button.
I have recently replaced the thermostat, and the guts of the monovalve, because of other issues. If I just want outside air it's fine but I would like my A/c coming into the warm months. Any solutions?
