I tried this fix yesterday with mixed results on my 02 Highlander. My original wires appeared to have overheated so I tried the complete re-wire fix. I have never used a soldering iron before so it was a definite challenge.
I now have heat, however my function dial does not work (Feet, hands, defrost, etc). These functions do work when I move the temperature dial a little, but then I have no heat! So I either have full heat set to defrost, or no heat! (its a start
)
Also, the circulate air light seems to flicker on and off randomly. Too cold to try the AC, but I suspect that is FUBAR as well.
I fear that I have messed up the circuit board. Any ideas? If I retry the solder job, is it a waste of time?
Thanks for the advice!
