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 8-cyl

2004 Grand Cherokee. Consumer states pulse module problem. The consumer stated the air conditioning unit ceased to function. The vehicle was taken to the dealer where the problem was diagnosed as a bad plug connector. They repaired the connector by cleaning and re-installing the pins at a cost of $170. Shortly thereafter, the unit once again ceased to function. The consumer stated he had to wiggle the plug in order for it to work and it only worked intermittently. The consumer was informed a repair kit was available with replacement parts. The dealer informed the consumer they would ship the parts to his hometown. It took approximately 2 1/2 months for the parts to arrive only after numerous phone calls. Upon inspecting the malfunctioning parts, the consumer found that they were badly burned and the wires were melted.
