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.

Water comes into the car from under dash board and affects the blower motor or motor switch where it works intermittently or often not at all. The problem continues even though I've had the blower motor and switch replaced because water continues to enter the vehicle under the dash. Happens in the rain or if I go through a car wash. Anyone know why water would be able to enter and how to fix? I'm thinking the solution may be something simple, maybe a space between the wind shield somewhere that allows water to enter through the dash on the passenger side and soak the floor?

I've recently noticed that the blower motor don't turn ON when is required, even when I start the A/C (the check engine light is ON) I check the codes to see the problem and appears the temp sensor.. however when I've sent to repair, the mechanic mention that both fans are working perfect I don't know why sometimes turn ON and sometimes don't.

My mechanic doesn't know where the water leaks in from. He believes me after I brought it in after my last car wash. It was -25 C. The blower filled with water and didn't work. He took it apart and it was frozen solid. More ice found in the housing. Now that its dried out it works perfectly.. Until it rains or I wash the car again... Or use the windshield washers.. Otherwise the blower fills with water and works intermittently. Powering up and down as the water swishes around. The floor on the passenger side always gets real wet too. Once left outside during the rain, we had one inch of water from front to back seat on the floor.
