I have a problem with my 2003 Kluger Grande also called Highlander in USA.Its intermittent but most of the time the airconditioner controls, sat nav, outside vent air controls and radio auto functions wont work. Sometimes it all comes back on and all works fine, but then it stops again. I have pulled the head unit out and wriggled the wires but cant find which one is the poor connection causing the fault. Does anyone have any ideas or experience of this? I have ordered an electrical manual which might help to track down the problem, but its very time consuming and frustrating! Please help anyone??
