Po481 fans run but won't cycle to high and it's overheating.

Hi,

This could be the result of a few different things. It's likely an open circuit in the cooling fan high relay circuit.

If you look below, I provided the diagnostics specific to your vehicle and the code you provided. Take a look through them and let me know if you are comfortable performing them.

Let me know,

Take care,

Joe
