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.

problem #1

AC compressor just wouldn't shift on. having three kids and summer heat reaching 115 degrees it was impossible to go anywhere without AC. had the compressor removed and tested, report was OK condition so had same compressor reinstalled. i changed out all relays, fuses, and electrical wiring to the compressor and it still refused to switch on. finally bought some extra wiring and ran a bypass cable from the compressor directly to the positive battery jump terminal and to the ignition coils fuse under the hood. AC works just fine now and compressor switches on as soon as the engine is started. in order to run the heat after the weather changes the bypass MUST be unhooked and grounded to prevent the compressor from being fried.
