    The illumination bulbs were out on my AC controls, ECT, rear window button, rear defroster, and power point.

    This is a write up on the step by step process I took to replace the bulbs.

    My research was done here: ***************************************************************************

    After reading thru those threads, I determined I needed the following part numbers. These are for a 2001 4runner, the bulbs for other 4runner generations might be different.

    2001 4runner limited climate control light bulbs:

    Part Number #81850-35050 - 2 Total
    Part Number #81850-35040 - 2 Total

    Hazard control light bulb:

    Part Number #84999-10860 - 1 Total

    ECT and Defroster light bulb:

    Part Number #90010-01041 - 1 Total

    Rear window roll down:

    Part Number #90010-01042 - 1 Total

    Cigarette lighter:

    Part Number #84999-10250 - 1 Total

    ***************************************************************************

    Ordered all my bulbs from Camelback Toyota:

    Removing the center console cup holder, this is done by tugging it off:

    Then removing the shifter surround:

    [​IMG]

    Next, the radio surround is removed, gently pry it away from the dash:

    [​IMG]

    Pull it out slowly to reveal the plugs by the ac vents:

    [​IMG]

    Unplug the power point plugs:

    [​IMG]

    [​IMG]

    Once the power point plug connector has been removed, locate the bulb - it is the gray end of the power point:

    [​IMG]

    Twist to remove:

    [​IMG]

    Next, I removed the hazard switch:

    [​IMG]

    This is done by releasing the side tabs:

    [​IMG]

    Next, I removed this portion:

    [​IMG]

    This is done by releasing tabs at the ends AND at the top center:

    [​IMG]

    [​IMG]

    Next I removed the AC controls faceplate, tabs are on top. This is very flimsy, so careful:

    [​IMG]

    [​IMG]

    I then removed the screws that hold in the AC control unit, disconnected the rear plugs and pulled it out:

    [​IMG]

    At this moment, I went ahead and installed the power point bulb:

    [​IMG]

    Time for some surgery. Hazard switch:

    [​IMG]

    Twist and pull out the bulb, replace with new one:

    [​IMG]

    Now the strip, this has two bulbs. One for defroster and ECT, another bulb for the rear window switch:

    [​IMG]

    A needle nose pliers will allow the removal of one of the bulbs.

    [​IMG]

    To remove the other, the backing must be removed, a small flat head screwdriver helps here. I then removed the other bulb and replaced it.

    [​IMG]

    Next step of the surgery was to open the front of the AC control unit. I removed two screws. FOUR tabs need to be released on the top and bottom. Forks or toothpicks help keeping tabs open while I worked on other tabs.

    [​IMG]

    Carefully opened the AC control unit..

    [​IMG]

    [​IMG]

    Bulbs removed and replaced:

    I then assembled the AC control unit together.

    Reinstalled everything back together.

    Finally have all my illumination working properly!

    I'm looking to this on my 2002 4runner soon. Is there a color option on the bulbs?

    If its stock OEM light bulbs.. NO.

    If you upgrade to LEDs (aftermarket), yes.
