OK, it's my Dads 96 Town Car.
It has been sitting for a while and we now noticed the rear end is sagging badly, so we start it up and let it run but the pump does not turn on to raise it up.
We have checked all the fuses and the switch is on in the trunk area.
Does anyone know what to check or look for next.
Thanks, Jack

 

Check for power to the pump, it's under the air box in the left front fender. There is a relay for it in the fuse box and a 40 amp fuse (mega fuse).

 

if the pump is getting power and everything checks out there you might want to look at the rear ride height sensor, i don't know offhand where it would be located on these cars but if thats telling the car its high enough up then the pump won't kick on no matter how low it is actually sitting
