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.

1999 Jeep Grand Cherokee Owner Comments

problem #1

Dec 102013

Grand Cherokee Limited V8

  • Automatic transmission
  • 120,000 miles


Just spent a lot of money to have the entire dash torn out to replace the heater core and now blower will not work at all. Could be Blower Motor Resistor (?). Getting fed up with all these issues and they are only in the HVAC system - haven't gotten to posting about the stalling out, transmission that won't shift when cold, etc...

Note: It seems the entire HVAC system of several Jeep models and years is faulty and prevalent across the Internet. The next thing to happen after the blend door failure is that you could not alternate between air conditioning and heat unless removing the glove box cover and toggling it from one thing to the other. Next, the heater core failed entirely and saturated the passenger floor. Now, after having the heater core replaced (not cheap!), the blower won't function at all.
