I did drain the cooling system for a timing belt and water pump change. And when I did refill the system and bleed it both fan turn on, and the cooling is blowing coolant from the cap. But the gauge of the panel doesn't move from the middle. 1.Checked fuses under dash and under hood, working good. 2.Tested relay, by removing it and checking for continuity on terminal #1 and #2, while applying battery power to terminal #3 and ground to terminal #3, working good. 3.Jumped the two wires going to the fan switch, and fan turned on. 4.Measured voltage between the #1terminal of the radiator fan relay and body ground, 11 volts. 5.With ignition on II checked the voltage between the #3 terminal of the radiator fan relay and body ground = 11 volts. 6.Checked for continuity between the #2 terminal of the radiator fan relay and the #2 terminal of the radiator fan motor – 2 pins connector, got continuity. 7.Checked for continuity between the #1 terminal of the radiator fan motor – 2 pins connector – and body ground, got continuity. 8. Measured the voltage between the #2 terminal of the radiator fan switch – 2 pins connector – and body ground = 11 volts. 9.Removed the yel/grn wires connector from the “coolant temperature sending unit” and turned ignition to II position and grounded it, the needle on the dash moved up to the hot position. And when I am driving the car it stay in the middle range, never got to the high range. 10.Tested the “radiator fan switch” with hot water and I got continuity from the 2 pins terminals. 11.I run the engine at 1500 rpm and again both fans came on. And today I did install a new thermostat and new radiator fan switch, and still both fan are running even though I did not turn the A/C on. Now and running the car with A/C on, because it is how I get both fan running. Please I need some advice.
