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.

2003 Jeep Grand Cherokee Owner Comments

problem #1

Sep 152008

Grand Cherokee 4.0L

  • Automatic transmission

The cooling fan would not shut off. I went to a local repair shop after finding out that the relay was behind the front bumper. The repair shop charged my $200.00 to replace the relay. 6 months later the relay went out again. I decided to find out how difficult it was to replace myself. It turns out the repair shop didn't remove the front bumper. They cut a hole in the plastic bumper under the left headlight to gain access the the relay. The new relay was $50. It still was a bit of a pain. The battery, battery tray, and headlight had to be removed. One thing to note: this is a solid state relay and they are prone to failing in the closed position which would cause the fan to stay on and run the battery down.
