First check for 12V to the fan motor. If no voltage, check radiator fan fuses (No. 21 in under hood fuse box), and radiator fan relay. If these are OK, wiring or connector is faulty.

Are you sure the thermoswitch A you replaced was correct temperature rating (93C/199F)? The other thermoswitch B may be identical but has a 106C/223F rating.

good luck

Hey WOW,I got a link to work finally.....[sm=happy046.gif]


See if this schematic helps you. I seem to remember/think the Green wire from the control module can be grounded with the key on, and fans should run and that proves out the whole circuit.

Well when the temp gauge shows about 1/2 way you should have continuity thru that switch.
Also you can unplug the switch,[at the Tstat housing]stick a jumper/paper clip into the plug teminals and turn on the key....the fans should run, and putting the jumper in and out will make the relay in the underhood fuse box CLICK.

“I jumped the switch on top of the t-stat, the radiator fan cuts on and I get the clicking sound from the relay.” You now have eliminated all but the fan switch (sensor) you just jumped and coolant flow around this sensor. My 1995 when the head gasket blew would not overheat unless it idled for an hour but the fans did not kick on unless I shut the engine off. I guess the air getting into the cooling system from the cylinder prevent coolant flow around the sensor.

If you follow Hondadude’s suggestion you will down to two answers “Well when the temp gauge shows about 1/2 way you should have continuity thru that switch.”

Please do the test and post what you find. Either the switch is bad, wrong part, or the coolant flow is not getting the switch up to temperature.

I have seen Thermostats give the same problems you have. Not letting enough coolant flow to activate the switch and just open enough that the vehicle overheats sometimes. Air in the system would give the same Problem. Did you bleed the system?
