Heater Blower not turning on even on High
My heater blower has been intermittently turning off and wont work even on high setting. I am not sure where to begin to start looking for the issue if its the resister (assume not as it doesn't work in full high). I saw a relay for my blower motor not sure if this needs to be replaced. I have not seen a location for a fuse yet.
I have a 2000 F250 Super Duty 7.3L Diesel.
any help appreciated.
