I recently bought a super nice 2004 crown Vic. The day after I bought it, the air ride quit and the fuel pump went out. Put a pump in and and it’s running great but I can’t get air ride working. I took the compressor off and put 12v straight to the electric motor and got nothing so I ordered a new one but I’d like to get the car up while I’m waiting. I tried to put air into the air line under the air box and it won’t take any air at all. I figured solenoids weren’t opening so I replaced the ride height sensor and still get nothing. Also the switch in trunk is on and all fuses and relays are good. Under dash and hood. Wiring is good all the way back and up through the trunk. What’s my next step?

 

There are kits to replace bags with springs, not sure about shocks You t*be had instructions onn how to do it and keep[ check engine light off.

 

I did the same to my 97 Town Car. Very simple to install, less than $100, and IMHO rides nicer. Has a life time warranty too! Also a lot of the time the pump goes out because the bags are leaking. So if not replaced, the pump will go out again. Even if it wasn't leaking bad, the pump was probably weak, and as soon as you put a decent air source to them...
