Possible bad fitting wher lines connect.
SOURCE: Problem with AC, dual climate zones
The temperature blend door on the driver's side might be broken or stuck. Also, if this vehicle does not have the correct amount of refrigerant, it will do what you are describing.
SOURCE: ac not working, blows hot air only. Recharged
Check the evaporator coil by sniffing the vents,floor is best, with your tester.
SOURCE: air condition blows hot air but it has freon
You may have created an over charged condition and at this point the a/c compressor will cut off on high head pressures. This can be verified by installing gauges to the systems high and low side service taps and reading the pressures.An overcharged system will start the compressor briefly but soon cuts off once pressure goes to 350 - 400 lbs on the high side. Acceptable pressures for this system should be no greater than 250 high and low suction should drop to 40-50 psi.You might recover the charge and evacuate the system,then try bringing the charge back to proper level.A sight glass in the reciever drier really helps determining proper fill.Once all bubbles have dissipated from the sight glass during charging ,one should stop at that point to avoid overfilling.Too much freon is worse than a low charge especially in hot ambient conditions....
SOURCE: 1999 Ford F150 AC fully charged with freon is blowing hot air
there are few things you need to check out:
1. if the compressor is overcharged it will shut down and you won't get any cool air
2. the thermostat for your cooling system is bad
3. the link to adjust the temperature is too short (did you feel the switch loose when changing temperature from hot to cold)?
hope this helps.
SOURCE: AC blows hot air
my 2003 l200 did the same thing...ended up being a leak or hole in the ac line.
- thin metal and exposed to the elements will do that.
