The ECU is under the glove compartment attached to the side. You may have to take a few of the surrounding panels off. I'm not sure what year your car is so i'm not possitive.

The thermo switch has a two terminal connector not three (see picture). Perhaps you located the wrong sensor.

The thermo switch is connected to YEL/WHT and BLU/RED wires, not gray wires. Does your thermo switch look similar to the one in the picture? Do you have an aftermarket A/C system?

Jumper wire only the two connector terminals leading to the YEL/WHT and BLU/RED wires.
