2002 Ford Crown Victoria - Air conditioner blower not working
Cool air is there, however, the fan will not engage. When you push the fan button on the steering wheel it does show the lit icon for the fan. Checked the fuses, they are all good. Owner's manual does not cover this. Thanks in advance.

The Blower motor on this car is under the hood. It is on the passenger side fire wall. It very easy to change as compared to most cars, I can do the job in Twenty to thirty minutes The blower motor is available as an aftermarket part, and should be under a hundred dollars.

The air conditioning condenser creates a lot of heat when the a/c is on. The cooling fan is supposed to run the whole time the a/c is on to keep it cool. If the fan isn't on, the radiator will absorb this heat and cause your car to over heat. You should also check your coolant level. So, it sounds to me like your cooling fan isn't working.
Check the heater control valve. This valve opens to allow hot coolant into the heater core and closes to cut off the flow. It should be located on or near the firewall behind the engine. It should have coolant hoses attached to it. Look for an arm on the valve which should be attached to a cable coming from the heater controls inside. This arm should activate the opening and closing of the valve. Check to make sure it moves properly.
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.
You have a vacuum leak. Defrost is the default postion(no Vacuum). Start by finding the small black vacuum line near the heater hoses at the fire wall under the hood.Trace it back, it should go to a square black reservoir . Not totally sure exactly where it is located on this model,shop manual doesn't show a very good pic, but it states to remove wiper arm and pivot shaft to remove it. You will see a second line going from here to intake manifold vacuum port. Make sure you don't have a leak there somewhere.
