When air condition is turned on, I can hear the compressor kick in but the fan does not come on an blow air. I have misplaced my manual for my 2004 Crown Vic LX - do no know where the fuse box is and the size amp that is needed. If it sounds like something else is wrong please let me know. Can you help me please, it is extremely HOT! Thanks. Rose

first of all why did you charge the system it never needs to be recharged unless you have a leak in it that being said when you turn on the ac do you hear the compressor clutch kick in and if so do you see condensation on the accumulator and does it feel cold? yes/no if yes then the vacuum door inside the car is not opening thus giving you warm air========if no the refrigerant leaked out again because of a leak ///// or the cycling switch is bad///// or there is still not enough refrigerant in the system to get the switch to turn on the compressor//// or your compressor is n/g
Ac is not blowing out cold air. You have to put gages on the system and it shows its has freon.Checked all fuses and relays. The two fans in engingine compartment do not come on when the ac is turned on but does when the engine gets hot. The compressor engages when turned on also. If the magnetic clutch engages the compressor and still no cold air could be still low in freon or the HVAC unit.
Blower motor not working all the time...if I bang the dash near the glove box, it comes on then works great. Is this the switch assembly, the resistor problem, or should I be replacing the blower motor?
If your a/c compressor kicks on and your manifold gauges show proper hi/lo readings then I would inspect the blend door. The blend door is a motor that moves back and forth when u set the temp for hot or cold . In your case, it may be stuck in the same position. The blend door is located in the dash, usually behind the glove box or in that general area.
I hope you are able to fix your problem.

Roger it sounds like the blower motor is not comming on. There is a resistor network located in the engine compartment on the passenger side mounted to the firewall, that controlls the blower motor. The connections may have corroted or the unit itself is bad. That was the first thing I had to relpace when I got my used 92 Dakota. There is also a 30 amp fuse in the fuse box under the dash board . If that is blown I would suspect the blower motor is seized up or just pulling too much power.
What you are most likely hearing is the compressor kicking on/off. The constant kicking could be a sign that there's insufficient refrigerant to keep the compressor running continuously without shutting on/off. Eventually, the compressor won't kick on at all, a safety feature designed to prevent doing damage to a compressor that's undercharged. Have the AC system checked.
I also have a 2004 Kia sedona with approx. 80,000 miles on it. The air conditing system stopped blowing cool air into the car. The fan would work, but would not blow cool air. After doing a lot of research. After trying to find a car repair manual or diagrams for the Kia Sedona with no luck. We ended up taking it to our machanic. He then replaced the compressor and it is working fine now. I now know that this is common for the compressor to go out on this van.
