    2007 limited

    New relay
    Freon is between 30 and 40psi
    Low side.
    Mag clutch engages when I jump the relay.
    Cleaned cabin temp sensor
    New cabin air filter.
    All fuses and relay are new and good.. I don't want to start throwing parts at it just yet.. it all started when I put in a new AC blower motor. Did I wiggle my way into a costly repair?
    Green light of blinking death.

    Green light blinking means there is a trouble code in the AC amplifier.

    Best thing to do is find someone with a good scanner than can read the code.

    Could you have broken a wire in the servo harness while changing out the blower motor?

    I know mechanic in fact I only know enough to get myself in trouble.. but I was leaning towards the amplifier as well I remember seeing a post someone saying just resold her some of the connecting points but I'll do a closer inspection of the amplifier later today.
    Thank you very much for confirming my suspicions I'll let you know what I find out

    The AC amplifier seems to be in good shape without putting it on a computer and it's really no way to test as far as I know. I did a auto recirculation test and it shows no sensors being faulty..
    With the truck running in the AC clutch engaged by jumping the relay did a head scratching looky-loo.. and I noticed that the clutch is a little wobbly my question now is if I jump the AC relay forcing the AC clutch to engage and the AC works perfect could it still be a bad clutch?

    The ac amp is responsible for sending the signal to close the relay. Need to find out what is keep the amplifier from doing that. Like I said if the green light is blinking it has a trouble code in it. I don’t think the amp is smart enough to see a loose clutch or throw a code for that.

    I would be trying to get a good code reader on it.
