I have a problem with air flow from the vents when I drive for 45 minutes to 1 hr. The AC works great around town for short trips but when I have a long trip, after about 45 minutes air flow almost...

the evaporator is freezing up, this then limits the air flow. if you stopped the vehicle and after a short time a very large pool of water would be leaking out of drain tube from vehicle (on ground under vehicle) confirming this. some water is normal. the evaporator thermistor or temperature sensor (thermostat) needs setting or replacing, or checking that it hasent fallen off of evaporator core.this then causes the air compressor to continually run and not cut in and out like it should, so it freezes up after longer operation. A/C system being slightly over full, or sticky/jammed open TX valve can give same symptoms also. take to automotive A/C place to check system with pressure gauge set

Interior leak

Could be connected - - the drain for the ac could be plugged up and the water is dripping into the passenger compartment. The system may be low on freon or have a restriction in the line which could cause it to freeze up. Could be an air flow problem with the cooling fan too.

I have a 96 chev. caprice classic and the a/c doesn't work it just blows hot to warm air what is the problem?

Most common low on freon,or the low pressure cycling switch,If its beacuse its low you should fix the leak and refill.

There is water the fills the floor of the passenger side of the car when the air conditioner is running

The AC condensation drain is clogged, when the AC is on water is condensed on the cold AC evaporator core (this part is what cools the incomming air), this water drains out the bottom of the heater/AC air duct, the drain is at the bottom of the firewall under the hood on the passenger side, run a coat hangar up into the drain to clear it.

2000 Jeep Wrangler 4.0 liter: Air conditioner drips condensate on passenger side floor. Is there a drain somewhere that could be plugged?

There is a drain tube on the lower part of the firewall that is probably plugged.Normally I use a pick to dislodge debris some use coat hangers but you must be careful not to poke at too hard and cause a freon leak in the evaporator core.

Restricted air flow 98 grand am has new heater

yes the ac evaportater can get plugged with dirt and debris like leaf matter, also check to see if your car has a cabin air filter, if it does that can cause the problem, consult the dealer for more on this filter, not sure if your car uses one..

Honda acac sometimes blows some kind of dew air throught he vents

u most likely have some condensation building up in evap box ,,need to clean it out before it gets worse,,,if u are running it on low blower ,it is going to put out mist sometimes (if the air is really cold) because of the expansion valve pulling down the tempurature

Low air flow from AC/Heater fan on '98 Chev K2500

check the cabin air filter behind the glove box, if it is ok or is not equipped (was optional) then the problem is a clogged ac evaporator core.

2005 LS Jag engine - air conditioning works on long trips sometimes, then all of a sudden we get no cold air and the air flow reduces to about nothing. I stop the car (gas station for 5 minutes) and go...

Sounds like your evaporator is freezing up.There are several things that could cause this like low freon charge,restricted orifice tube,ambient air temp sensor,evaporator discharge air temp sensor,AC pressure transducer sensor.
You might want to get someone experienced on that vehicle to take a look at it.
