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.

Replacing the evaporator is a royal pain in the ass. The whole dashboard assembly and everything in it needs to come out of the vehicle. I would not recommend anybody trying this unless you have plenty of time and patience. I found a white piece of foam inside the evaporator case that I believe was intended for vibration control. In my case it seemed to block half the cooling fins (less airflow= less efficiency) and prevent proper water draining (probably contributing to corrosion and failure). This is likely installed incorrectly in other vehicles, and obstructing the drain hole causing wet carpet.
