You have to remove the complete unit out. it just kinda snaps out if I remember correctly. there is a circuit board that you have to remove. There are a few screws holding it in. Be careful handling the board as to not emit any static electricity that would take out the ic's on the board. You will find a small circuit board mounted where the temp control is. Go assuming you have taken the knobs off in front and removed the nuts on the controls, you can unclip the board and pull it out. There is a 3 wire cable connecting the circuit board to the temp switch. Mine had a broken wire at the small board. Be very careful trying to solder this back. It requires a small tip and not too much heat. Hope this helps. Better than spending $800 for a new one or $300 for a used one. Rut

Replying to: slowcar (Jul 20, 2009 1:35 pm) I have the exact same problem on my 01' Highlander. The temperature range is approximately 12-18 degrees warmer on the drivers side as opposed to the passenger side. I will let you know if I come up with anything.
