Sounds like you need to check the air-bags for a leak. Unfortunately, the compressor may have wore itself out attempting to continuously provide air to the air-bag and may also need replacing. Just my $0.02 worth.

Sounds a lot like an Air/Vacuum leak to the rear Shockies..... See a Suspension Specialist....

Have you checked your battery voltage? Do your headlights come on? Could even be a dead starter. run a test on it with a volt meter.

Try using a jumper wire n test light to see if mirror switch is juiced n transmitting power on & off. If no current thru switch, then may change out. If power is transmitting; do same to mirror silanoid, motor. If direct current to motor & no movement? I ld replace motor. If both check out, then start traceing out wire; cuz its got short in it. Best way; if able or find someone u trust& have em use an Ohm meter. It ll let u know if wires are grounding out n if switch or motor good. Good Luc: BamBam

i'd think that the vent adjuster knob/slider is not working correctly strip out the heater panel around the control knobs and check the vent direction is working properly either stiff operation so a little wd40 on the cable would probably do the trick or some thing causing the vent itself to not move

its either a bad air control panel or u have a bad damper valve in your dash

More than likely it is a short somewhere in your electrical system. Check the water escape tube located in the center pillar of the car because if these get clogged, the water will enter the roof center controls where the interior lights are in the center of the roof. often times it is that this backlogged water can cause a minor short in the circuitry and then this will lead to sporadic odd behavior in the interior lights. they often will go on and off without your commanding it to do so, or sometimes they might stay on even though the doors are closed and so forth. when working on resolving the short, always unplug your negative battery cable to prevent you from hurting the vehicles main computer ECU unit. you will need a multimeter to assist you at finding the short. Also always pay attention to the ground wires in that they get rusted and corrosion can also cause odd and unique behaviors. good luck.

Check fuses and bulbs first if not its gonna be wiring issue. Make sure bulb sockets aren't corroded as. I've had this problem before. Hope this helps

On the car, you may find the 5 digit Code on a sticker on a trunklid hinge. Sometimes a sticker is in the doorjam or even under the bottom of the door. The sticker was put in areas that were concealed, yet accessible so that no one walking by would be able to read your secret number. Inside glovebox? Other than that, the Dealer may be able to match the Vin# from the original build details from your car.

I have found with these Crown Vic's,especially police cars,they manage when the get in accidents to hit the right front of the cars and when they do they damage the wiring harness. The rain,salt,snow get in the harness and you eventually have problems. Look under the car in front of the right front tire and you'll see. Good size wiring harness. Look at it for damage,or sometimes you'll see like a light green dust coming out of the harness. Usually where I find my breaks,shorts or opens.

May be low on fluid or you may have a leak.Add Mercon ATF oil to top this off

Check airconditioner filter,if it can be clean do so

It sounds like the wiper switch was going bad and now it has totally failed. OR, it could be the wiper motor itself is bad. If you can get to the wires that connect to the wiper motor, see if any power is coming to them when you move the wiper switch to each speed. If not, bad switch. Replace it.

These cars are known for this problem, and what I'd do is find a Ford Dealership mechanic's forum and ask there. You could also try calling the dealership part's department, and ask them. I'd bypass the dimmer, which eliminates all costs.
