Personally, I wouldn't bother because if you stop and think about it the relay can't really be stuck on.Check the radiator fan relay
It may be stuck on.
Well, it's nice to know at least one person reads my posts about testing relay circuits.avisitor said:Also, it can tell you which way to test next
Either the control side of the circuit or the load side
That would be my guess. Although, it might not be the sensor itself that's causing the problem.I now having a hard start when engine is hot, which I think the ECT is not working which probably was cause but the fan always running. ?
You could certainly do it that way but before going to all that trouble what I would try is unplug the relay and connect a voltmeter across the control terminals. then monitor the voltage as you turn the ignition on and see how long it takes for the meter to show 12V.Just test the control wire
Check it for short to ground with the wire disconnected from the PCM
If no short then test the wire with the PCM connected
Yes, it certainly does help one with one's diagnosis when one knows how the circuit is wired.avisitor said:It is always easier to troubleshoot a circuit when one knows the circuit
Congrats on the new job. There was a parts store near where I live looking for a delivery driver a while back. I was very tempted to apply for the job. A driving job beats what I'm doing now.avisitor said:Oh, switch my job to being a driver to deliver parts to commercial customers Unfortunately, very slow lately
