I'll throw one more success story into the mix. Today I used the information provided in this thread to successfully repair the same two broken leads on a 2002 Highlander. The dealership told us they tried to tighten some nuts that had worked on a previous Highlander they had in, but when that didn't work concluded they simply had to replace the heater control head for $986.00!! I am very grateful to everyone that has contributed. All the information I needed was found here. From the location of the wires to the pictures showing disassembly to the tip on using a spatula to pull the bezel without scratching the dash. Thanks to all.
