    P38A - Minor (but irritating) issues

    Getting ready to sell the Limo, and there's a couple of things have happened:

    1. No aircon - there's always been a blend motor fault shows up on nanocom, but this time there's fans, etc but no cool air.

    2. No cruise control - light comes on at the master switch, but nothing happens when you go to set the speed.

    3. Drivers side window - always had a bit of a tight spot halfway up, now it gets to the point it will stop the motor. I'm going to pull the door card tomorrow and have a look.

    Regarding 1 & 2 does anyone know of any common fuse/relay between these two?

    Gíday mate,

    #1 can sometimes be solved by replacing relay 6 and 7 in the fusebox, but you say you have blowers no worries, so Iím letting someone with more HEVAC experience take control of that one.

    #2 have a look at the condition of the vacuum lines for the cruise unit in the engine bay, passenger side. They perish and then the unit canít hold vacuum, thus no cruise.

    #3 will likely be just a matter of securing the regulator bracket. From the factory they are riveted in, the rivers break and cause this issue (I currently have the same thing, Iíve found tilting the window backwards by hand as it goes up is a temporary fix).

    Cheers
    Keithy

    Ok regarding number 1 the a/ c not working, iíd Start with the alternator!
    because if you have weak voltage going in, the a/c clutch wonít engage. Usually a tell tale that the alternator is starting to fail. So do a voltage check and make sure itís sitting above 14volts.
