looking for the fuse for the heater blower (30 amp). on some models its in a fuse box in the engine but i believe that this year just has useable links and then a box in the driver area
My car has an automatic transmission.
The 1991 E250 Econoline does not use a fuse, but a blue fusible link wire that is off of the yellow wire, which comes off of the power side of the starter relay on the fender. This then goes straight to the blower motor relay to power the blower motor through the blower resistor.
