    Default Climate control modules between model years

    The climate control module on my 87 lost it's low fan switch and the button faces are all chewed up and wrinkled. If I swap out to a newer years eg 1990 module is it still plug and play?

    Yes it is plug in play and works like it should. I have a 91 climate controller in my 87. The only feature that does not work is the front windshield defrost and floor vent combo button as the 86.5-88 models did not offer that.

    A failed low speed fan setting may be just a blower motor resistor ($30 or so part from the dealer). Don’t assume your control panel is bad just because of that.

    Like reklund5 said, it very likely the resistor. I have had it go on both of my supras.

    Can confirm that it wasn't the control unit, once I swapped the units the fan still didn't work. In fact last weekend I lost all fan control. Time to dig into that. At least the new one isn't all torn up from wear and exposure.

    Its just the blower resistor.
    Cheap fix.

    There are 3 small coils of different gauge wire inside that vary the resistance on the fan, resulting in different speeds.
    The wires corrode and crack overtime.
    Its an easy $30 fix.

    It is located under the dash on the passenger side and is mounted on the blower box it self. It is labeled 87138 on that picture and the part number is 87138-24030
