Before i did a motor swap my fan was working perfectly fine. Now it doest want work. Bought a used fan and well it still doesnt turn on . Checked the fuses under the dash and the fuse and under the hood and the small little black relay in the fuse box. Still nothing this car is ghetto rigged with the wiring i dont know anyone know if there is an actual ground that needs to be grounded to the chassie?

 

The ground should be on the thermostat housing. I think its the fan switch. Have you jumping the fan switch?

 

i got the paper clip and unplugged the connector on the thermostat housing and the fan didnt come on.

 

How about connecting the wires from the fan to the battery itself, and if it still doesnt turn on, the motor on the fan is shot. if it does, there is break in the wire somewhere.
