    Check Air Suspension light with rear susp swapped to coil springs

    My MGM had the rear air suspension swapped for coil springs before I bought it.
    So, up until now, I tolerated the result of a lazy man's job on it - the Check Air Suspension *ding!* light on the dash.

    NEVERMOAR! Time to get it sorted out. I got under the car and in the trunk - there are no air lines, so at least a part of the system has been deleted up to the compressor, which I believe is under the hood. The compressor switch in the trunk is OFF. Other than that, it's all unclear to me.

    The way I see it the control function for the air spring expects an "OK" signal from a sender at the compressor / pressure switch / air valve (?) and gets none; hence the *DING!* on my dash.
    Other than getting someone with a diagnostic tool for the Panthers and disabling this pesky light, the usual walkaround is — at least in GM vehicles — to fool it with a resistor bridging the end of the line that sends the air spring fault signal and kill the fault indication. I'd only need to know how to do this on a Panther.

    Ideas, gentlemen?

    There's a way to wire the switch wires to ground or something to eliminate that light. I don't remember which ones do the job, but the information is here, and someone will probably help you shortly.

      The light is on because the switch is off. If you turn it on, it should come on because it senses the missing parts, or it will come on when the ride height doesn't trim after whatever the internal timer is set to.

      There is a wire you have to disconnect in order to turn the light off, but I don't know which one. What year is the car?
