Hello and thanks for using justanswer.com
Did the refill kit have a gauge on it? If so what did it read?
Customer: replied 2 years ago.
At first read red which said too full or mechanic lee problems. Then someone released the freon by pushing the top valve open and it released all freon so then it was down all way we filled it to 32 lbs and it seemed like it didn't take near enough.

We may have a problem with the climate control module or heater valve provided the a/c system is working and the system presses are normal. Go to the left side dash and remove the side panel. You will see some connectors. We are looking for the green connector. Use a light and you will see each wire pin numbered. You are looking for the 14 way green connector. Make sure the key is off and disconnect it. With a voltmeter check for power on pins 9 (brown/green) and pin 10 (brown/white) on the harness side you disconnected. If power is present then leave the black lead of your meter to ground, reconnect that harness connector to the dash then start the engine and turn the climate control to full a/c. You should read low voltage on both pins and you should see it change as you increase/decrease the temp on both pins. If the voltage stays high you have a bad module and the valve is mist likely shorted.
We should first rule out a refrigerant problem so I recommend having a repair shop evacuate and recharge the system will the machine this way there will be no moisture in the system and we will be able to see the pressures on both the high and low side. Still run the test in the meantime. Let me know.
