If you are asking for a 1996 or newer model year, it is located just below the dash on the driver's side above the OBDII port. It is not hard to access. Drop the lower dash panel for light access and uncouple the harness clips. Slip it back and replace with the new one.

In the center of the dash. It's the unit you select options on. It controls the AC and Heat.
To reset the climate control module on a 2000 Grand Marquis, start by disconnecting the vehicle's battery. Leave it disconnected for about 10 to 15 minutes to allow the systems to reset. After reconnecting the battery, turn the ignition to the "ON" position (without starting the engine) and press the "AUTO" button on the climate control panel. This should recalibrate the system and restore normal function.

A 2000 Grand Marquis does not have struts, it uses a conventional shock/spring type suspension.
