1995 JEEP GRAND CHEROKEE — POWER TRAIN:AUTOMATIC TRANSMISSION:PARK/NEUTRAL START INTERLOCK SWITCH

BACKED JEEP INTO GARAGE AT 2:30 P.M.. POWER FAILURE AT 4:30 P.M.. AT 6:00 P.M. OPENED ELECTRIC GARAGE DOOR BY PULLING RELEASE CORD. PULLED JEEP OUT OF GARAGE FRONT FIRST. TO CLOSE GARAGE DOOR, PUT JEEP IN PARK, LEFT DRIVER SIDE DOOR OPEN AND WENT BACK INTO GARAGE TO PULL RELEASE CORD. LOOKED UP, FOR SOME REASON, AND JEEP WAS BACKING INTO GARAGE ON ITS OWN. JUMPED OUT OF THE WAY, HITTING MY FACE ON CAR AND TWISTING MY BACK. JEEP'S DOOR CAUGHT ON GARAGE FRAME AND FINALLY STOPPED VEHICLE. JEEP DOOR NEARLY TORN OFF. CALLED JEEP AND INVESTIGATOR CAME OUT TO DO TESTS ON CAR THE NEXT DAY. SAID THE COMPUTER INSIDE CAR WOULD SHOW IF THE CAR HAD ACTED ON ITS OWN. INVESTIGATOR SAID TESTS SHOWED EVERYTHING TO BE OK. EVERYTHING MAY SHOW OK NOW, BUT THAT DOESN'T CHANGE THE FACT THAT IT CHANGED GEARS ON ITS OWN. I DIDN'T GIVE MYSELF A BLACK EYE! HOW DO I PROCEED?*AK
