air suspension on 2005 Lincoln Town Car

There is a fuse box under the hood beside the battery . There is a relay and a fuse to the module. I had a mechanic check them and he said they were good . After I replaced the module and the height sensor . I took it to another mechanic who replaced fuse 112. The first mechanic used a Sunnen fuse checker with the fuse still in the car. The second mechanic took a fuse he knew was good and began swapping it with each fuse until the pump came on. Old school but it worked. If I had taken it to the second guy first I would have several hundred dollars. I now have a spare module and leveling sensor.
