I'm glad I could help. I'm reposting the solution below in case anyone needs it in the future. Please be sure to rate it for me!

Pull the temperature knob off and verify the thin 12mm nut is installed and tight behind it. I have seen several of these loosen up allowing the knob to turn but intermittently have no effect on temperature.

SOURCE: Toyota 04 Highlander Temp Control Problem

Hello. Thank you for requesting me. We have been seeing a large amount of Highlanders with temperature control issues. A replacement control is in the proximity of 900 dollars. After the fifth one sold, and some really unhappy customers, I decided to see what the issue was that was causing the failures. It turns out that the problem is nothing more than a broken wire of two. If you are handy with tools, and can use a soldering gun, you can fix it yourself. The problem with the controls needing replacement is a broken wire or two at the circuit board that controls the temperature (the center knob). This is unfortunately common, albeit an expensive repair. Here is how you can fix it yourself: What you will need: Pencil-type soldering iron, rosin core solder, a Phillips screwdriver, a 10 millimeter socket, extension and ratchet. First, remove the plastic fascia that surrounds the radio/heater-AC control. (Be careful to not crack it when removing it.) Next, remove all of the 10 millimeter bolts that holds the Radio/AC-heater control assembly to the dash panel, and unplug all of the wiring connectors. Next, remove the three control knobs on the Heater/AC control panel, and the silver nuts that holds the controls to the panel. They pull straight off. (Under the center knob, you will probably find a loose nut, this is what caused the wires to break, the control is loose in its holder.). Next, turn the assembly over, with the back facing upwards. You will see a rectangular black box. Remove the screws that hold the black box onto the back side of the front of the control panel. There will be a ribbon-wire connector that will need to be removed from the front panel; be careful when removing the black box?s connection, and take care to not damage the connection ribbon wires. Next, remove the entire circuit board from the panel cover, by removing several Phillips screws, this will allow easier access to the control board that needs the wire(s) soldered. At this point, you have two choices: You can solder the broken wire back onto the control?s board, or, if you desire, you can remove the ribbon wire, and replace it with different wires; personally, I choose this path, and I use telephone wire, three lengths, that I strip and solder to both locations, each of the three on the main board and the other end on the control board. Either way will work, as long as you solder the wires back properly, and avoid any possible shorts by allowing the solder to touch an adjacent lead. Once you have soldered the broken wires from the temperature control board back on to the main circuit board; reassemble the parts and refit it assembly to the dash. Thanks for choosing FixYa for assistance today; I hope that this helps you out, and saves you a bunch of money.

Testimonial: "Thanks so much for the detailed instructions! Sure enough, 2 wires were broken. My husband was able to make the repairs, and the control gauge is now working perfectly. Thanks so much!"

SOURCE: The heating controls don't work on my 2002 Toyota

Hello. Welcome to FixYa. Please allow us to assist you.

You have one of two possible problems.

1) The retainer nut for the temperature control is loose

2) A wire is broken from the temperature control sub-circuit board to the main circuit board.

If the retainer nut is not loose, the unit can be repaired. This will entail removal of the heater control from the dash, disassembling it, identifying the broken wire, and resoldering the broken wire back in place.

If you are not skilled in disassembling the dash and the heater control, and not skilled in soldering, this job is best left to a professional. The alternative ti repairing the broken wire is costly. The replacement control is roughly 900 dollars, plus installation. A qualified technician can repair your control in less than 2 hours.

If you need further assistance, please feel free to get back to me.

Thanks for choosing FixYa today.

Where is the fuse for the 2002 highlander ABS

The fuse for the ABS in a 2002 Highlander is in the black plastic covered box under the hood. If you take the fuse out, the ABS warning light and the emergency brake warning light will illuminate on your dashboard. The brakes will work as if you never had ABS, and the car will chime when you first start off if the emergency brakes are on.

2002 Toyota Highlander AC main control

Before tearing out the AC control, does the temp knob feel loose or wobble alot more then the fan knob? If so pull the temp knob straight off. Look at the small nut around the shaft the knob came off of. Its common for them to come loose. Just tighten it up some and reinstall the knob. Your temp will work normally now.
This fix is for the manual system not the auto ac system.

Dash Control Unit Replacement

You can save a LOT of money by fixing it yourself.

All that is wrong with the knob are broken wires from the knob's PC board to the main PC board on the AC control.

All you have to do is remove the AC main control, take it apart, and resolder the broken wires from the PC board with the knob on it, to the main AC pc board. There are 3 wires, any number could be broken.

If you take it apart and solder the broken wires, this WILL fix your issue. Just make sure you put the wires back exactly where they go.

A FIXYA rating (4 blue diamonds) would be most appreciated for my assistance.
