I realise that this thread is getting on for 8 years old now, so forgive me!

I'm having this same issue, and there are some great posts in this thread, but unfortunately most of the pictures are missing!

So.. I've removed the tape and conduit from the fan control module back up to the first T but can't see any broken wire. Due to the lack of photos, I'm not sure if I should be looking in the top of the engine bay (I removed the air filter housing) or from underneath.

I have a few questions if anyone is able to help!

I have no voltage on the PWM wire on the plug. Does the car need to be running for this? I have 12v on the other 2 pins.

I have an oscilloscope so could check it - but again not sure if car needs to be running.

I've checked fuses and relay. Both fine.

Is there a way to check the fan control module?

Thanks!

Hi which are the 2 fuses and relay thanks
