    I want to replace my hvac controls. Some of the sliders are very hard to get moving. Also one of the plastic levers is broken.
    I found what I think is the correct part number.
    The folks at JP CarParts say it has been discontinued and the controls for a 1990-2004 model can be used.
    Among other things they wrote:

    55910-90K00 is replaced by 55910-60220.

    Can anyone confirm? Will control cables be the same? I will replace them too.

    This would be good info to know, mine are in similar condition. I'll be watching closely.

    Interestingly, the part is the same for both RHD and LHD. I guess you just flip the unit to suit either LHD/RHD?

    May be hard to confirm. Perhaps a long wait.

    I would bet that they keep the same orientation but the blower motor control knob offsets the sliders right or left as needed.

    What is causing the levers to be stiff?

    If you force the levers the plastic do-dads that move everything behind the dash will break. Ask me how I know this.

    Hello,

    x2.

    Levers may have lost lubrication over the years.

    Heater and AC levers are hard to move in old age. Some contact cleaner and oil may help.

    Be careful not to force them when disassembling.

    My two cents.

    I think the control cables have corrosion causing stiffness.
    The middle lever feels broken. Very hard to move and a lot of slop.
    Spray lubes have no effect.

    That's why I'm looking into replacement parts.

    The problem might be at the ducting flaps rather than the controls

    Something in there has some friction/corrosion, cables or duct flaps. I cringe every time I move em.

    It feels more like crusty cables that led to moving plastic parts deforming, cracking etc.
    Outside/inside air duct flap has been lubed. No change.

    I think the previous poster is referring to all the doors for the different selections, like floor/dash vent/defrost. These all have their own doors.
    I changed out this cluster on the -75 when I got home with it since the plastic arms where broken for some of these functions. I had another rhd set here. All works, but I still don't get full windshield defrost, some day I will have to look into that.
