Electric fan cutting out.
Been chasing an overheat issue. Finally determined that my 2-speed electric fan was cutting out on high after about 15 minutes of driving. Replaced both high and low speed relays and the switch. Test drive yesterday with same results; temp going up rapidly at the last 2 traffic lights before getting home. Shut off the engine and the fan was not running, it is direct wired so it can be run without the ignition on. Turn off the fan switch and then back on and the fan comes on. Can the fan motor be intermittent , and why cutting out after a certain period of time? Any other ideas?
