93 air ride pita.

[kingairpilot]

I am working on a friends 93 Mark. The compressor runs all the time, does not time out and the switch in the trunk will not shut it off. Is it the computer box or relay? Any ideas? Will not pump up the bags, just runs for ever.

had that on a Grand Marquis, the bags and a line were shot, then the motor burned out
