How to fix 3rd Gen HVAC blower switch

Since buying my 4Runner last June, the lowest/1st position of the blower switch hasn't worked. In my situation, root-cause was a bad blower switch resistor. I picked one up from my local Toyota dealer and swapped it out tonight.

1. Remove glove compartment assembly (glove compartment and mount-bar)

a. Pinch both sides of glove compartment so the tabs release the box from the I/P compartment. The box should flop down, giving you better access the the (3) mounting bar 10 mm fasteners.

​

2. You'll see the resistor installed vertically, with (1) philips head fastener at top and bottom.

​

3. Unplug and remove bad resistor. Once mine was removed, I took advantage of the access and vacuumed out a whole bunch of bugs, twigs, leaves, etc. etc. that collected in the intake area behind the resistor.

​

4. Install new resistor and put everything back together - and enjoy ALL the speeds of your fantastic 3rd Gen 4Runner blower.



Merry Christmas, Happy Holidays . . and many happy miles!
