Hi,

This could work either way. For example, the fan may not come on if the clutch doesn't engage which can be as simple as the AC needing to be charged.

Have you checked to see if the system needs to be charged? Take a look at this link. You may find it helpful.

Next, I attached the wiring schematic for the radiator cooling fan. Check to make sure the fuse is good and confirm there is power to and from it.

Here is a link that you may find helpful:

Start with this and let me know the results. If you look at pic 3 below, I highlighted the cooling fan fuse, compressor clutch fuse, and compressor clutch relay.

Here is a link that explains how to check a relay:

If there is a different relay in the box having the same part number, switch them to see if it makes a difference.

Take care,

Joe
