    Rear a/c changes temp without command

    Yes, I have a tech 2. I'll check for codes for that. I forgot this can have codes for stuff like that. Oops. It does have the 'auto' function on the control in the front climate control. I disconnected the wire to the blend door actuator (middle of the rear hvac assembly blend door actuator...

    Rear a/c changes temp without command

    Hey all, truck has done this a few times. Never stuck around though for me to troubleshoot. The rear ac usually blows nice and cold... well suddenly today it started blowing hot(heated) air. Turned off rear ac, front blows cold the whole time. I checked the controls front/rear and they were set...

    I plugged the level control module in. compressor turns on and stays on now (until it shuts off I'm assuming for heat reasons), then turns back on after a wait time. Both new pumps do this. Does a level control module that was a used part(got it from ebay, same part#) NEED to be programmed? or...

    just got my used level control module in the mail. I thought I could use the tech 2 to reprogram it but it seems I need something else to do so? Help?! lol

    nah, it seems to be sealed. just the mount was broken off. so it was just the silver part and the connector.

    I pulled it down, cleaned connections etc. No change after that. The module is supposed to be riveted to to a mount, the rivets failed and I was able to remove it as soon as I touched it. I'm guessing that much vibration etc could damage it? Weather has been crappy when I've had free time its...

    So the rear shocks should show 0% when I'm not driving essentially? I'm suspecting the level control module as well now. This is what i was worried would happen trying to stick with the factory air ride lol. Any idea where i could get a level control module besides dealer (I'm on a...

    I will check that when I get a chance to lift it up and get underneath lol. I did mess it with it some more today. I jumped the relay connection (battery to the blue wire). both compressors worked in that configuration lol (ran for 30-40 seconds no problem). only 1 turns on for self test with...

    connection at the pump looks close to perfect considering 168k miles. I'm going to try and jump the relay in the next day or two, see if it will stay running while its jumpered so I know its at least not the power wires. Also going to check the chassis module/computer (whatever that is called)...

    Well, picked up a new unit (dorman). Doesn't work at all. No self test, exh valve and compressor don't do anything via tech 2.

    oh ok gotcha. did all of the above. still can control exh valve, no compressor does not turn on other than for self test. I also tried raising/lowering the front and rear to see if it would trigger a adjustment (it didn't). I did see a code for C0660 'level control exhaust valve circuit short...
