Question about 1999 Ford Explorer
Problem with air conditioner
First you need to make sure your testing you ac when the car is on. If its still blowing hot air make sure you have the ac setting set and not the fan setting. If thats not the problem make sure the compressor in the ac is running it give off this distinct humming sound when the ac is turned on, you might need to put your ear next to it if you can find it. If the compressor isn't working check the wiring in the car, and make sure the fuse/chip for the compressor are fine.

compressor or receiver/dryer or condensor may need to be replaced. Further testing will have to be done. Look into your sight glass and see if there is any bubbles in the glass, or if glass is extremely foggy. If so, you may have air in the system. Check to make sure you are getting power to the compressor.

Probably, to be sure make sure the compressor is coming on. With the engine running turn on the ac and watch the rpms, they should drop for a second if the compressor is coming on. If so you just need to recharge, the refrigerant is R-134a, which you can get from your local parts store along with the kit needed to charge it. The kit will come with detailed instructions and is a pretty easy job.

Sad to say, but you have to get a new condensor, what's more important you must get your lines flushed out, if not it will affect your compressor, then you're talking big bucks. See if a local guy can also add and auxilary fan to the front of your radiator, It will really help circulate the air and you'll have less wear and tear on your complete air con units. Also, make sure you change that air con filter. That little filter is also important. Good luck and drive safe. Hollywood Harv

How do you know it needed freon, without gauges its hard to know, most people add freon because its not cold and that may not be the problem, in turn they cause more damage to the system,these vans are famous for leaks.check all the fuses,then jump the low preasure cycling switch and see if compressor truns on,youll need to look at the clutch to see it turn,then the next step is to check the lowside and highside preasures,

Most likely your problem is the same as mine, which means you have a crack in your air compressor therefore no matter how full you fill the freon it will always drain (or blow) right out. Solution - get a new air compressor. Try to find one in a chop shop junk yard type place if you can do it yourself.
Alternate problem - freon can lose its charge. You can take it to just about any auto store and get the freon charged up for about $70. If that doesn't fix the problem it is likely the compressor.
