The fan relays on your Continental are located at the top center front of the engine compartment above the radiator. You really do need a diagnostic tool, however, to test the different components. A proper diagnostic tool can "active command" a fan to blow at high or low speeds. Then you can perform testing for power and ground and check the relays and the motors themselves.
Good luck on this!

Thank you for helping . What is the( diagnostic tool )and where can you get one? Can't you use a volt-meter ? Where are the relays ? THANK YOU !!!

I'm sorry Jimmy, but a diagnostic tool is a pricy tool ($2,000 - $5,000 or more) that can interface with your vehicle's various modules and work with the components in an effort to troubleshoot them. There's more to the systems than resistance and voltage, which you can certainly check with your voltmeter.
Even with your voltmeter, you could check for power at the motors -- this would rule out the motor as the cause of failure if/when you find you have no power there.
In the end, the command to power the motors cannot be checked by a voltmeter, and the diagnostic tool is needed.
