2005 Toyota Highlander Limited AWD 4dr SUV w/3rd Row (3.3L 6cyl 5A)
Temperature control stopped working. I contacted parts department at local dealership. Knob was 'okay' but told unit was faulty and would cost $825 to replace (not including dealer costs). Found a website that discussed same problem with Highlanders and Tacomas. Friend & I removed heater/air- conditioner unit. There are three welds for temperature on left side and system control on right. Two of the three welds on the temp gauge had broken. Rest of unit is made up of electronics and circuit boards. My friend has worked on RC vehicles and was able to take care of re-welding parts. Now works almost good as new & I saved lots of bucks. I'm not happy that Toyota hasn't id'ed problem
