Hello. I have this exact problem on my 2002 Highlander. I actually talked the dealer into trying to solder these wires but the were not successful in getting the wire from the ribbon cable soldered, and because the whole process scared them to death, they gave up easily. Can somebody advise me on what size/type of replacement wire to use and what 'size' (how small?) of a solder gun do I need to do this? (I have no experience soldering).
Thanks,
Jack

The second shot shows the back of the heater control unit with the cover removed showing the main circuit board and the small circuit board (circled) on the back of the control knob.
The third shot shows the ribbon cable where it breaks off at the solder joint on the small circuit board.
The fourth shot shows the three wires I soldered in place of the ribbon cable.
