Do you have A/C gauges to check your Freon? If charge is insufficient. low pressure switch will prevent compressor from engaging. If charge is suffient replace low pressure switch.

SOURCE: 1996 crown victoria has no heat

i think it is the heater control valve i think it is mounted on the firewall by the top close to the hood it will have two black 5/8 hoses attached to it check and make sure it still has the cable attached to it before you replace

good luck here is the (how to) for your car



The heater control valve (sometimes called the water flow valve)controls the flow of coolant into the heater core from the engine.
Heater control valves are operated in three basic ways: by cable,thermostat, or vacuum. Cable-operated valves are controlled directlyfrom the heater control lever on the dashboard.
f48-04_3184.gifCable-operated heater valve used to control the flow of water or coolant through the heater core.Thermostatically controlled valves feature a liquid-filled capillarytube located in the discharge air stream off the heater core thatsenses air temperature and modulates the flow of water to maintain aconstant temperature regardless of engine speed or temperature. Mostheater valves utilized on today's car are vacuum operated. These valvesare normally located in the heater hose line or mounted directly in theengine block.
To replace a heater control valve:

  • Refer to your vehicle's service manual to locate the valve.
  • Drain or lower the fluid level in the cooling system.
  • Unclamp, unbolt and unplug the valve.
  • Reverse procedures to complete installation.
CAUTION
Identify the heater control valve carefully. It is easily confused with other parts.

SOURCE: The compressor and fan don't come on when the air conditioner is turned on and hot air comes through the vents. However, when the relays are removed and a test wire is inserted into the relay port, th

Sounds like a bad heater control unit, or bad control module. You are bypassing the switch when you jump the relays, so usaully the switching mechanism is suspect.

Fuse 9, 50A under hood, Fuse 5 15A Instrument panel. If they're ok, make sure the compressor clutch can be turned by hand (engine off, obviously). If not replace the compressor. Most common problem is the cycle switch. That should be the electrical connector on top of the accumulator. Just jump that by backprobing the connector on both sides with a pinand connect them, with the car on and a/c on if the compressor clutch engages, replace the switch. If it doesn't, try wiggling wire harness and watch it, if it engages, find a broken wire and repair it.

Hi billberger2

When the air conditioner turns on, the car computer also increases the engines revs to counter the load of the air con. It should not generally be noticeable however. Will do some research to see why. :)

Air compressor locked up what alternative vehicle belt can i use to bypass the a/c compressor on a 1999 crown victoria


does the diagram of the belt routing on the core support say one with ac and one w\o ac? if so autozone can tell u, if not, they may tell u that you need to replace the ac compressor, or buy some thing that re routs it. you can also try to remove the compressor, that way its out of the way, and take a string, run it as it would go, and measure the string, that will tell u what size belt to get

1992 CROWN VICTORIA LX I REPLACED FUSES INSIDE AND UNDER HOOD FOR AIR RIDE SUSPENSION AND IT STILL WON'T AIR UP. PLEASE HELP


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.

My 1998 Ford Crown Victoria was running just fine when parked Thursday evening. Friday morning, the air condiioner compressor will not come on. The fan runs--everything else runs fine.


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

94 Crown Victoria air conditioner won't kick on


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
