i have had the infamous p0691 code, as a result the aircon does not work as the fan wont come on when it is switched on, i can see where the purple wire in question ends up in the cooling fan, i have read that this wire goes straight to the ecu/pcm, which connector and pin does purple wire end up in the ecu/pcm? can i just unplug the connector from the ecu/pcm and get a resistance reading between that and the cooling fan end to confirm a break somewhere in the loom? is the ecu/pcm accessed by taking the front left wheel and wheel arch off?
