try rechecking the blend door actuator and its connections, fuse, etc. also if your AC system is overcharged it will blow warm air.

Try to check this link and download the Crown Victoria Owners Manual (page 273 and next).

Hope this helps (remember to rate this answer)..

CHECK THE REAR SENSORS AND WIRE.
THEY MAY HAVE BEAN PULLED APART OR RUST IS FOULING THE SENSOR PICKUP.

I think that if you lift by the pumpkin and put your jack stands under the axle tubes you should be fine.It's when you lift and suspend by the body you can over extend those air shocks.

IT LEAKS HOW DO YOU GO ABOUT LOOKING FOR A LEAK?

You probably have a leak in the system. Did "they" check the lines and air suspension? "They" probably disconnected the compressor to keep it from burning out from overuse. You need to fix the leak before reconnecting or the compressor will wear out very quickly.

I have the same issue. Mine is a leak in the air suspension. The first thing to do is go to your under hood fuse box (the one with the oversized fuses) The fuse will be a 30 amp (large green) fuse. If the fuse is blown just go to Pep Boys,Kragen,or Autozone and they are less than $3.00. If this fixes it the air suspension will fill up within a couple of minutes (with car running) Usually these fuses will blow when you have a leak and the small compressor that fills your suspension gets overworked causing the fuse to blow. If that is the case with your vehicle keep a couple extra fuses handy until you get the car serviced. The only time you should flip the switch to the off position is when you are raising the car on a jack. Make sure the switch is flipped on when you replace the fuse.

There are actually two fuse boxes, at least on my 01 Vic CVPI. The primary one is under the dash on the driver's side and to the left of the steering column. the second one is under the hood near the battery. Your owner's manual should have a diagram as what fuses control your car's accessories. Hope this helped! Bill
