Add me to the list...

The climate control on my '01 Highlander started having problems a few weeks ago. It would blow extremely hot air randomly when driving with the AC on. I'm guessing the bumps caused intermittent shorts with the loose wires described by everyone.

I brought it to my local mechanic (non-dealer) since I thought it was compressor related. He guessed it was the expansion valve (which I had a hunch it being since my Google search led me to believe it). The work costed me $300 including parts, labor, and new freon.

The problem seemed solved until a week ago when it happened again. Tried to Google the problem another way that wouldn't just point me to the expansion valve. Ended up getting a link to this site which I forgot that I used to subscribe to back when I had other problems with my Highlander.

I just checked and my temperature knob is really wobbly. With the AC on, it stops blowing hot air when I tap the knob gently. Bingo! I already have solder, a solder gun, and 24 gauge wire laying around so it's tomorrow afternoon's project!

I love this forum!
