2002 Jeep Grand Cherokee Electrical System Problems

I currently own 3 of the same vehicles myself, my husband and my son. Each of the vehicles have been experiencing electrical issues. I have taken all of the vehicles at some point back to the mechanic for repairs for this issue. It was only a temporary fix. Here are examples of some of the electrical issues. The blinkers and break lights may go out and not work while we are driving and some days they work just fine. But it has now become a safety hazard because we never know when they will work and are afraid to be hit by another car from the rear. Another example is when I am driving down the street all of the sudden the windows will automatically roll down by themselves. These issues have put all of our safety at risk, especially while we are driving in high traffic areas such as Atlanta, Georgia. The problem was acessed by our auto mechanic on all three (3) vehicles. They are are 1999-2000, 2001 & 2002 Grand Cherokee one of the vehicles is a limited edition. There are no warning signs or symptoms and the check engine light is not on any of the vehicles.

AT START UP AIRBAG LIGHTS STAY ON I STOP AT THE STORE AND SHUT OFF THE ENGINE AND START IT BACK UP THE AIRBAG LIGHTS ARE OFF. ISSUE 2. DRIVING DOWN THE ROAD AND START UP A HILL IT DOWN SHIFTS OR HIGH RPMS A FUSE BLOWS.

RIGHT REAR PASSENGER WINDOW DOESN'T OPERATE AND FALLS OPEN WHILE DRIVING; WHEN I HIT BUMPS IN THE ROAD UNTIL THE WINDOW IS FULLY OPEN.

I REPORTED THIS PROBLEM A MONTH OR SO AGO ABOUT THE FRONT DRIVER'S SEAT BREAKING AND BREAKING OFF THE VEHICLE FRAME. PLUS THE A/C ISSUE UNDER THE GLOVE COMPARTMENT OVERHEATS AND MELTS THE MECHANISM AND CONTINUES TO BURN. WHEN I REPORTED THE ISSUE, NO WRECK WAS INVOLVED. SINCE REPORTING THE PROBLEM, THE VEHICLE WAS INVOLVED IN AN ACCIDENT AND TOTALED. MY FIX APPARENTLY ALLOWED THE SEAT TO STAY ON THE FRAME BUT THE SEAT STILL BROKE. FORTUNATELY, NO SERIOUS INJURY, ONLY SORE NECK AND BUMP TO THE HAND.

WIRES GET HOT THAT LEAD TO THE HEATER/AC FAN. THE INSULATION OF WIRE AND CONNECTOR MELTS. THIS CAUSES THE HEATER TO GO OFF AND BACK ON INTERMITTENTLY AND FREQUENTLY UNLESS YOU WIGGLE THE WIRES. WIGGLING THE CONNECTOR WILL HELP FOR SHORT PERIODS OF TIME. THIS OCCURS WHEN THE CAR IS RUNNING(DOES NOT HAVE TO BE MOVING) AND THE BLOWER IS ON. I HAVE TRIED TO PRESS IN THE CONNECTOR OR WIGGLE THE CONNECTOR WHILE DRIVING AND THIS IS A DISTRACTION. THIS HAS HAPPENED CONSISTENTLY BEGINNING ABOUT A MONTH AFTER I BOUGHT THE CAR. THE LOCATION OF THE CONNECTOR IS UNDER THE GLOVE BOX AREA. THERE ARE MANY INSTANCES ON THE INTERNET THAT DISCUSS THIS ISSUE.
