I have a 1984 Lincoln Mark VII - BMW Turbo Diesel - with approx. 46000 miles. It has set in the garage for awhile and I needed new tires. Got it running and the air suspension was working. The guy who did the tires knew about the switch in the trunk so it got turned off. I had a sticking caliper on the left front disc brake so I changed that myself. Somewhere in all that work my check suspension light quit working and my air pump wouldn't run. I bought a rebuilt pump online as the other one was getting weak. Plugged in the new one but no doesn't run. I can however hot wire the pump from the battery and air up the system then turn the switch off in the trunk to keep it from venting off and drive it. Still, I can't seem to figure out why I have lost power to the suspension light and pump. I have checked the power pin in the compressor plug and it shows hot. Does this mean there is a problem at the height sensor and if so why won't the check suspension light come on?
