简介
The dog got into the front seat of the Highlander and knocked the left seat heater control knob out of its natural position in the seat heater control switch module. This guide shows how to disassemble the seat heater switch in order to fasten the potentiometer switches into their proper seated position.

Place the gear shift knob down into its downward-most position to make it easier to remove trim panel.
-
Fortunately it is easy to remove the panel. Grab the right and left trim for the panel section - use can use a trim tool but I prefer hand control once I have the edge pulled. Pull outward and slightly upward on each side firmly but carefully.
-
-
-
With the trim panel pulled outward, release the three electrical plugs by pressing in each connector tab at the back of each module.
-
With the panel totally disconnected and removed, it is easy to pop the heater control module out of the trim by pressing the tabs and pushing the module out.

First slip the top cover off by getting a small flathead driver and gently prying up at each of the four tabs. I just used my fingernails to hold the edge up while moving around the module. It doesn't take much pressure to pop and lift these off the tabs.
-
Then you do nearly the same thing with the module housing piece by getting a flathead under the plastic at each of the four tabs and gently prying that side, using fingernails as needed!

The module consists of a circuit board with the two knobs protruding out to the front with another circuit board pressed into the back side.
-
In the photo you can see the potentiometer knob to the left is loose.
-
The third photo shows the two potentiometer switches and their ribbon cables connected to the backside board. The backside board can be pulled carefully straight out from its tucked position. Note that there is a mating connector holding the backside board into the front board.

-
In order to secure the loose potentiometer I needed to pull the knob ends off of their shafts and then work the board off of the tapered ridges around the module.
-
Hold each shaft near the circuit board and firmly but slowly pull each set of knob ends (black end piece with a clear piece and a thin gasket) away from the shaft.
-
With the knob ends removed, carefully work the circuit board out from behind using a plastic spudger or similar tool at the board edges.
-
-
-
With the board removed we can finally access the fasteners used to secure the potentiometers to the module center.
-
Here I just tightened up the nut finger tight and then realized I could get my craftsman 1/4" deep well socket over the top of the potentiometer shaft. I think the 5/16" socket is the correct fit but don't hit it too hard.
