Bypassing the CCRM

Bypassing the CCRM
I'm Jack, and I have had my Mustang for a few years now, and personally know the man who sold it to me. In the past year and a half it has been consistently overheating. I replaced the sending units, and that didn't help. I then replaced the CCRM, and it helped a little, but it seems my fan still won't kick into high speed. I'm curious if anyone can give me some pointers to bypass the fan speed modulator and just have the fan running at high speed at all times. I figure this would be plausibile, considering all fans used to run so long as the water pump was running, since the fan was mounted to it in old cars. I don't know much at all about cars, so any help at all would be much appreciated.

If you trace the wiring back you should see it connects to a relay before connecting to the solenoid. Disconnect it and run it straight to the solenoid only to test that your fan clutch isn't gone. I wouldn't leave it that way, it will burn out before long. If the fan is capable of running high then I'd look at the thermostat or the relay as possibly the cause.
If it won't run high in testing, you probably have a bad fan clutch.
