    Been a while for me due to family stuff but I'm back to attending to my lady. She's a 2011 #1446

    My heat & ac quit a while back. I thought it was maybe 400v controller but ac light would go on, controller light was red and diagnostic menu showed the fan switch was working. Once I got access to the fan I turned on the car and found the fan was on but just barely with no change with the switch. I pulled it appart to get to the plug and wired in 12v directly. The fan came on a little bit more, surged a few times, then quit. Wrestled the fan out and wiggle the brush tabs on the side and tapped the shaft a few times with a wrench and now it blows hard.

    To get access;

    1 Pull plastics over radiator
    2 Pull 400v controller
    3 Drain & disonnect the cooler inside the fan shroud by moving the single allan head.
    4 disconnect main brake lines at junction block
    5 unbolt brake boost
    6 disconnect brake pedal via pin
    7 Remove entire brake assembly
    8 undo two small 8mm nuts on front side of fan shroud with long extensions
    9 rotate and wiggle fan shroud up. You may not to remove it to get a few taps in.
    10 If you do need to remove it, it has a drain connected on the bottom that looks like wire loom. Reach under and remove.
    11 wrestle the fan out and service

    Welcome back @twiersum! We miss your colorful (literally and figuratively!) updates so great to hear your back to work on the resurrection of #1446. For the uninitiated, feast your eyes on this and this.

    Quick sidebar to this thread... did you ever get the MS motor installed/working?

    No, decided to wait until my ESS dies completely before I go that route since I'd be pilling a lot more amps. I did decide it's do-able though!
