Hi all,
When sitting in heavy traffic my engine water temp starts to increase gradually after 5 mins. As soon as I start moving again the water temp drops. Simple assumption is an airflow problem.
I've popped the bonnet expecting to see the rad fan going when running higher temps but it is not moving.
I've popped on the A/C also (I hope i'm right in understanding one of the fans helps with the A/C) but neither fan is operating.
Is there a simple checklist, course of action to determine what the fault is & how should I do it?
Ie: motors, relay box, fuse, ecu... etc.
its a 2005 350 with motor driven fans.
Thanks
