Code 33 and Blowing my heater fuse...?
So its about 30 degrees in Maine and im cold. Everythings been fine for a while but just recently i replaced my starter... once that was done and i got the car running it wouldnt let me turn on the fan for heat. great, well i checked the code and it gave me 12-33-55. So its the a/c relay... but i dont have a/c or the relay. I did check the fuses in the cab and it does in fact keep blowing the 25 amp fuse for the heater / fan. I'm out of ideas and i would really like to have my heat back. Would just buying a relay for a/c stop the fuse from blowing or do i have some short to ground problem

Unplug the fan motor and see if it still blows fuse. If it doesn't then motor is probably ok. If it does then it sounds like a shorted wire.
