Hello my name is ***** ***** thank you for your question,

The fans are controlled by the IPDM. Do you have a Volt meter to do a quick test? Would like to see if the fans are getting power. It's quicker to check that then to actually access the fuse in the IPDM. That is why I would like to check that..

let me check that. What next if no pwer
Expert:  Jay replied 2 months ago.

What you want to do is turn the engine on and turn the AC on. This way we know that the command is being sent to turn the fans on. Then check for power at the fans. If no power is present, then we will need to access the IPDM which is located behind the battery. So the passenger side wiper cowl cover will need to be removed along with the plastic around the battery as well.

Okay. I checked and there is no power to the fans. I started the can ran the ac and the car almost over heated but still no fans
Expert:  Jay replied 2 months ago.

Ok.. So if you have no power at the fans with the engine running and AC on, then we will need to check fuses. Hang on while I get you the fuse location.

Do you have a Test light? We need to check main fusible links and fuses. If they are all good, then you have a bad IPDM.
