1988 lincoln mark vii my air ride compressor will not come on what could it be and why


There can be several reasons. The system will not activate unless all the door switches and the trunk switch indicate everything is closed. There are some fuses and Relays for the pump motor that can be checked. There is a cutoff switch in the trunk which is shut off for tire service and other things requiring lifting the vehicle.

Some of the better scanners can check the Air-lift system systems. You can call Autozone, Advance, or Oreilys to see if they have the better scanner to do this. Usually free at these brands.

Can I bypass the air system to fill air manually


On the Mark VII, they came with an emergency fill schrader(like a tire valve) valve on the compressor head. To use this, simply apply compressed air to the Schrader valve WHILE THE PUMP IS RUNNING. The reason I say while the pump is on, is because if the compressor is on, the solenoids on the front or rear WILL be open, thus allowing air into the air spring(bag).

Most likely have a leak in the front air system. Could be a line or one o the air bags. Could also be a missing or misadjusted ride height indicator.

Air suspension front left side low


Most likely the airbags have a leak in the bags themselves or the air lines they have conversion kits that switch to coil springs for about $250 bucks at Strutmaster.com. Or go to a junk yard and get some used bags and lines for about $50 bucks your choice. Good Luck

I have a 1990 Lincoln Mark VII, the air ride was removed and now there is a short somewhere causing voltage regs to fry and draining the battery. We found a connection under the hood (passenger side) and...


after replacing the air system on your Mark, you should have turned the switch off in the trunk and left the air pump intact.....that way the system does not know that anything has been done....you can then just remove the bags and tape off the lines.....basically it does not know when to air up bacause of no pressure changes....all of the electronics on the mark vii are tied togather in the wiring harness and the best thing to do is nothing...plug everything back up correctly and try to turn off the airbag system in the trunk and see if that helps..
