    Quick cycling is a classic indicator of low freon, you may coincidentally have a separate problem.

    It could also be the blower control module. Mine just stopped working after a 200 mile drive thru the desert
    Had air on the way up and when I restarted The car to go home the air conditioning would not work. I’ve diagnosed it was the BCM should have it here in a few days.

    It was low on freon. The shop added some dye to the freon so we can determine if there is a leak.

    I don't think so... the BCM only controls the blower speed. Blend door actuator controls the temperature of the air entering the cabin.

    Check the bottom of the receiver / dryer. It's made out of steel and since there is insulation wrapped around it it will hold moisture and has a tendency to rust our on the bottom.

    I believe the Four Seasons 83148 is an aluminum one.

    Make sure they also replace the orifice tube if they open up the system.
