Low on refrigerant, Have system checked for leaks. If no leaks, they will charge system and if all is well, you'll be cool.

How to Recharge Your Car Air Conditioner

there is usually a sensor on the condensor unit, check that sensor, ive also had problems with the switch/button not working correctly

You can clean the filter of the ac and try maybe it can work

There are 2 ports, a high pressure and low pressure port. Both are in the engine compartment. I would suggest you get someone who knows air conditioners to do the work. This can be dangerous since Freon is extremely cold and can cause burns (freezer burns). Also you can damage your air conditioning system, and then it will cost big bucks to repair.

Your AC system has a leak and can come from many areas within the system. A pressure test done with the correct gauges will find this leak. Freon in the AC system does not disappear, unless it has a way to escape. Low or no freon will cause this issue and your cabin filter will not cause this issue.

yes i have my blower went out.It is your blower

there a restor on the front frame rail on the drivers side that gos bad it behind the bumper

hello,seem you need to send your car to authorized dealer to scan the problem,maybe the solution is only synchronizing all the flap,ty

it may just need freon put in ,it sounds like the pressure sensor wont let it turn on cuz of it being low on freon

This sounds like the A/C developed a leak and the safety switch won't let the compressor engage due to low refrigerant. It's probably time to take it to a service center and have the A/C checked for leaks and refrigerant level. You don't need anything off the internet until this check is completed.
