1998 Crown Victoria air conditioner

sounds like the temperature blend door is either jammed or the actuator is shorted ou. when the temperasture control is moved you should hear the door moving...my guess is you are not hearing that..the actuator would be attached to the heater plenum behind dash/glovebox area...becareful to test the correct one as there will be a fresh air actuator and a mode door actuator as well...you can determine which one is which by changing the positions on heater head from hot/col, floor/defrost, recirculate and fresh air settings..each setting will move its designated actuatror..the one not moving would be you temp actuator....have fun!

Air ride suspension basically works like this. you have a small air compressor and a sensor that connects between the rear axle and the under body Frame. When this sensor detects a load movement like more or less weight it turns on the air compressor to air up or opens a exhaust valve to let air out. most common problems with this system. broken or disconnected sensor. leak in the air lines between compressor and shocks. or a bad or weak compressor.

If you turn on the defroster and it still doesn't blow are check your fuses and if they are good replace the blower fan. If it does come on then you have a problem in your AC/Heating controls.

Sounds like the problem is in the air bag suspension, not the compressor. The air bags shouldn't be losing air when the car sits. The compressor adjusts the suspension level according to the load. The air bags have a valve similar to a blow up raft that allows air to pass through both ways. If when the car is running the compressor is constantly running and not turning off, the issue is within the air bags and/or the air line.

Hopfully it's a fuse, if not a fuse then check relay, if not the relay, then check the clutch on the coompressor, while the motor is off, check to see if the AC compressor clutch will turn freely, if not, replace the compressor.

find your evaporator inlet outlet lines on the fire wall usually near heater core inlet outlet lines. then follow both lines until you find the one that goes to the compressor. that is your low side and the port should be on there

it may need a charge of 134a,to check to see if the compressor is good then unhook the plug at the air dryer(silver canister) should be a light green wire and a black wire,put a paper clip as a jumper between the 2 wires and turn it on,if the compressor works then you need a charge,if it doesnt work then it could be a fuse or relay but that doesnt happen too often

hello, have you tryed filling your compressor with r134 coolant ?if it blows but the air just is'nt cold then sounds like this is your problem.

You dont need to remove all of those thing to do that. Working on the passenger side, remove the globe box and then the air bag, you are gonna see the bolts there. Now yo can see the black box behind the globe box? you have to remove the screws, some from the inside and some from the ouside (very hard to reach, under the box of the AC box outside).
Lifth the black box of the heater core and change it!!!

I would change the thermostat in the vehicle first and go from there. Hope this helps......Dan
