I woild be checking the vent controls as if the ac is working and the core was blocked then the air would be cool when the heat was selected but not changing Fixing the heater has resulted in a /c not being good enough to cool the air if the vent is not properly selecting. The point is that if the vent selection is not working properly (vacuum hoses) then the 2 faults will be related.

Your Air Conditioner might be low on refrigerant. If the AC doesn't cool down and had signs where it took a while to start cooling, you likely have a slow leak. It could be that an O ring wore out and started leaking, or a hose developed a leak. Rubber components tend to be the first parts that wear out over a period of time. A shop can confirm if your 134A refrigerant leaked out of the system.

you need a ac charge or the heater control valve is bad also check the compressor

Had similar problem. The actuator that opens & closes the air blend door quit working. This is easy to see if you remove glove box. The actuator will move when you adjust the temp selector (do this while the heater is running).

Could be a number of things...electrical connections causing the compressor not to run. Turn on AC and turn your thermostat all the way to cool...now visually check to see if compressor is engaged and not just free wheeling. Most likely you lost your refridgerant due to leak in the system...would need to find leak and repair then have your system re-charged with refridgerant. Best case scenario...your system just needs a charge of refridgerant due to not having enough.

start car.turn on air conditioner high cool .raise hood look to see if the compressor clutch is engaged and running.if yes your ac air door could be stuck closed or the air door vacuum actutator not receiving vacuum.a vacuum line is broken or off. or the control switch bad.that control the AC and heater mode. if compressor clutch is not engagged.check for power at compressor clutch.if yes compressor clutch coil open. or the air conditioner refrigerant R 134 is low take car to a private garage with a good reputation. they wont be expensive as the dealership.have them hook car air conditioner to a manifold gauge set to check your refrigerant low side and high side pressure.

you need to begin by changing the thermostat. if you dont know how go to an autozone and they will assist you.

if that doesnt solve the problem you need to change the heater/ac blower relay.
