Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

problem #4

We bought 2 Highlanders on July 4, 2004. The heating cooling system of one crashed and produces opposite effects: cold when tuned to heat and vice versa. Now it only produces heat. When the problem started some years back, I asked the dealer's opinion and was told I needed to change the whole dashboard panel for $1,000. Of course I didn't fix it because I couldn't afford to.

While fan speed control worked, temp control did not work at all. Temp typically remained on full Hot, regardless of location of control dial. There is a youtube video of how to re-attach/solder the control panel, but I had it repaired at the dealer.

Was first told it would take a day or two to get the parts, then they called and said it would be ready that day. Always wondered if they actually replaced the control panel or just re-attached the connections.

This is annoying problem since I couldn't control the temperature. When turning heater, no heat sometime. When AC was needed, hot air came out instead.
