OVERHEATED-Radiator Fans will not come on
Folks, here is the run down.
I've spend some time reading the forum and can't find anything here that sounds like my problem.
I have replaced the fan assembly,radiator, thermostat and coolant sensor.
Tested the relays-OK
Jumpered relay terminals-Fans will operate
Checked wiring at the relays- power where it should be, grounded where it should be--
Except I have no way of knowing if the PCM is grounding the fan relays
Oddly enough, on initial start of the engine, the fans will run for approximately 10 seconds then quit.
I took the PCM out about a week ago and cleaned the connector?
At first the fans came on and never went off. Then it worked properly for about a week.
Now it overheats. The fans will not come on.
Any ideas what is next.
