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.

My blower motor went out on me in 10 degree weather. The only way I got heat was when I was moving for the vent bowing in. It would randomly come on a off. I thought it was the switch. I went to the junk yard and got a different one and it worked, for a while. It then happened again so i returned that one and got another worked for a while and the same thing again. So I went to the dealer and got a new one for 300$, way to much for crap. It worked for an hour. You cant return electrical parts to the dealer once you plug them in. I played with all the wires leading to the blower motor and found a main power supply wire located directly behind the unit in a harness had a bad spot in the harness causing the blower to work a short time after I would replace the unit. So I took the sh*tty harness out of the equation and now it works great. I got stuck with the dealer part. Only good thing was all the lights work on it (for now). These are nice cars once all the bugs are worked out but if you are buying one make sure the tranny was rebuilt. This will never steer towards the problematic honda and toyotas.
