P0481 - should i try using something like AC pro

Question

Engine light comes on when AC on button is pressed

Answer 1

Hi there,

A/C pro isn't going to help with this. The code is happening because the secondary cooling fan isn't coming on when you turn the air conditioning on. This can be bad wiring, bad fan, a problem with the PCM or the cooling fan control circuit. These all need to be tested to determine the problem, once repaired the A/C should work properly and the fan should come on when you turn on the air.
