Tech help for 95 Mark VIII

[BobCat]

Hey guys,

my 95 dropped the air this last cold snap and now I can not get the front end back up. Any ideas? I tried reseting the trunk switch several times to no avail?

Thanks!

No compressor noise.

I have turned car off and on at least 10 times, along with switch. Still NG?

Check for power at the air suspension compressor relay connector.

Disconnect the relay with the car running and air ON, check that you also have voltage from the air suspension module to the relay's coil.

Reconnect the relay and check for voltage at the compressor connector itself (car still running)


If there is voltage at the compressor, there is an issue with it.

If there is no voltage at the compressor, and there IS voltage to the relay (constant hot and switched from air suspension module to turn on relay) you probably have a bad relay or wiring between it and the compressor.

If there is no voltage at the compressor, and there is NO voltage to the relay - you may have a wiring issue if all fuses are ok.
You did check the fuses, right?
