I have replaced the blower the resister and the blower switch and checked the wiring and could not see any damage to the harness it was working and then quit... fuse still good...... any thoughts and should the electic fan in the rad be running when the heat or a/c are on?

I know the electric fan should turn on when the ac is on but when the heat is on it should only kick on at 210 degrees or so...

This is for an 88 but i think things are pretty similar... doesn't look like there is a relay

There's a 40 amp fuse for the heater blower motor in the PDC under the hood. The Power Distribution Center is the black plastic box about 3"x 10"
hinged on the long side. It contains relays, circuit breakers, and fuses not contained in the passenger compartment fuse box.
