Yes that fuse goes directly to the compressor. The module energizes the relay which sends power to the compressor through that fuse. Could be a bad compressor. Place the black ground lead of your meter lead to the battery negative and the red positive lead to the top terminal on fuse #6. Start the engine and close the driver door to see if we have battery voltage there.
In order for the vehicle height to change the module will need to energize the solenoid. The solenoid block is located under the spare wheel and the module is located behind the rear seat back. It could be a leak, bad compressor or height sensor. We really would need to know what the stored fault codes are. A Jag compatible tool will be needed in order to communicate and read codes from the air suspension module.
