Replace low and high relay switches the 40 amp fuse in a 20 amp speed control for the fan. I tested the fan hook the ground wire to their ground on the battery after going to wire ran to the positive hook to my test light and I was able to get a good connection on the actual fan on the high side, but nothing on the low. Checked the plug goes in the wiring harness to the fan with my volt meter and test light with the motor running and can't get no power.

Good afternoon,

I attached a wiring diagram for you to view. Check the fuses for power on both sides with the key on.

Make sure there is a power to the relays, both of them.

The PCM will ground the control side of the relay once it sees a signal from the coolant sensor for temperature or the AC system is turned on.
