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.

Grand Cherokee 4WD 8-cyl

  • Automatic transmission
  • 85,000 miles
I own a 2003 Jeep Grand Cherokee limited with 90,000. The events leading up to the failure of the ventilation system were (1) rapid fogging of front windsheild, (2) fogging of front passenger windows, (3) failure of passenger heat while still maintaining driver heat function, and (4) only cold air release on passenger side of Jeep. Consequently, (1) the windsheild and front windows do not defog, and (2) no heat whatsoever comes from the passenger side floor and dashboard ventilation system. To correct this problem, a "blend air door" is necessary at a cost of approximately $1,200 inclusive of 7 hours of labor. According to the certified service department at the local Jeep dealer and online forums, this has become a very common problem for 2000-2004 Jeep Grand Cherokee limiteds with duel zone ventilation systems.

I turned on the heater/defroster to clear the windshield and only cold air would come out. After speaking to a few dealerships the all agreed on the same problem. It is the blend doors. It will cost me $90 for parts and $600 in labor for a vehicle that I had 4 months and only 44,000 miles. It is hard to drive in the winter with fogged up windows. Not to mention unsafe. I will keep the old parts.
