2000 Jeep Wrangler Electrical Problems

While driving at various speeds, your speedometer and tachometer suddenly drop to zero, while your fuel, oil pressure, and temperature gauges continue working normally. A few seconds later, your check engine light comes on and the odometer displays 'NO BUS,' then everything returns to normal after a few seconds to a minute. In some cases, your airbag light illuminates instead of the engine light, then clears on its own. This happens randomly but more often on bumpy roads, and never occurs when parked. The issue likely involves a loose or corroded electrical connection in the instrument cluster or a communication bus problem that a mechanic will need to diagnose with a scan tool.

OVER HEATING OF A/C - HEATER CONTROL SWITCH WHILE IN USE CAUSED THE SWITCH CONNECTOR, SWITCH AND PART OF THE HVAC CONTROL PANEL TO MELT. ON THE VERGE OF FIRE THE FAN STOPPED FUNCTIONING. RETRIEVED THE SAME UNIT OFF A DONER VEHICLE [1J4FA59S3YP733181] AND FOUND THE CONTROL TO BE MELTED/BURNT IN THE SAME FASHION. WHEN I LOOKED FOR A REPLACEMENT, THE PARTS SUPPLIERS OFFERED A READY-MADE REPLACEMENT WIRE HARNESS [POTENTIAL CLUE OF COMMON FAILURE]. THE MOPAR REPLACEMENT PART IS LISTED AS DISCONTINUED. I HAVE TAKEN PHOTOS OF THE ISSUES DESCRIBED, BUT WILL HAVE TO GET THEM DEVELOPED AND DIGITIZED [MY DIGITAL CAMERA WON'T TAKE CLOSE-UP PICS].

2000 JEEP WRANGLER. THE WIRING TO THE A/C CONTROL SWITCH SHORTS OUT AND CAUSES A MINOR FIRE. THE SWITCH HAS BEEN REPLACED AND IT HAPPENED AGAIN. THERE WAS EVIDENCE OF A PREVIOUS FIX IN SPLICED WIRING. THE WIRING HARNESS IS NO LONGER AVAILABLE. RESEARCH ON JEEP RELATED WEB SITES HAS PROVEN TO ME THAT THIS IS NOT AN ISOLATED INCIDENCE AND OCCURS IN MANY OF THE SURROUNDING MODEL YEARS. THERE IS A DESIGN FLAW IN THE THREE POSTS THAT CONNECT TO THE SELECTOR SWITCH, THEY ARE TO CLOSE TO EACH OTHER. *TR

MODE SELECTOR FOR THE HVAC SYSTEM HAS A MAJOR ISSUE MELTING THE SELECTOR, HARNESS AND CONTROL MODULE. AFTER RESEARCHING THIS INCIDENT ONLINE AND TO MY SURPRISE THERE IS NO RECALL ON THIS SUBJECT. HEATER NOT WORKING, POSSIBLE HEATER SYSTEM CATCHING ON FIRE DO HI VOLTAGE TO THE MODE SELECTOR WITCH CAUSES ENTIRE HVAC FAILURE AND POSSIBLE FIRE. JEEP HAS KNOWN ABOUT THIS FOR A WHILE BUT NO ONE SEEMS TO BE GETTING ON THEM ABOUT IT. AGAIN 2000 JEEP WRANGLER HEATER CONTROL FAILURE. *TR

TL*THE CONTACT OWNS A 2000 JEEP WRANGLER. WHILE DRIVING 30 MPH, THE AIR BAG LIGHT ILLUMINATED ON THE INSTRUMENT PANEL THEN BOTH THE SPEEDOMETER AND RPM GAUGE DROPPED TO 0. AFTER ONE MINUTE, THE GAUGES BEGAN FUNCTIONING CORRECTLY AND THE AIR BAG LIGHT TURNED OFF. THE VEHICLE WAS TAKEN TO A LOCAL REPAIR SHOP BUT THE MECHANIC COULD NOT DIAGNOSE THE FAILURE. THE VEHICLE HAD NOT BEEN REPAIRED. THE FAILURE WAS INTERMITTENT. THE FAILURE MILEAGE WAS 67,750 AND THE CURRENT MILEAGE WAS 67,900. THE CONSUMER STATED NO LONGER OWNS THE VEHICLE. UPDATED 12/30/10

HVAC WIRING HARNESS AND SWITCH MELTED DUE TO FAULTY BLOWER MOTOR COMPOUNDED BY INADEQUATE SIZE WIRE. CHRYSLER DOES NOT EVEN SELL A REPAIR KIT EVEN THOUGH THERE ARE NEW CASES CONSTANTLY ON THE WRANGLER TJ ON INTRANET FORUMS. SOME ARE EVEN VEHICLE CATCHING FIRE. *TR

INSTRUMENT CLUSTER WILL INTERMITTENTLY GO OUT, LEAVING NO SPEEDOMETER, ODOMETER, OR RPM GAGE. THIS CAN GO OUT FOR SEVERAL MILES, OR JUST BLINK ON AND OFF. IT HAS BEEN DOING THIS FOR A COUPLE OF YEARS, AND HAVE ALREADY ATTEMPTED TO HAVE IT FIXED ONCE BY A DEALERSHIP AND SEVERAL TIMES WITH MY SON WORKING ON IT. SO FAR NOTHING HAS CORRECTED THE PROBLEM. DEALERSHIP KNEW WHAT THE PROBLEM WAS WHEN FIRST BROUGHT TO THEM ABOUT 2 1/2 YEARS AGO BUT COULD NOT FIX THE PROBLEM. BEING ON THE COMMUNITY EMERGENCY RESPONSE TEAMS, I NEED A RELIABLE VEHICLE. *JB

HVAC SWITCH SHORTING AND MELTING PLUG AND/OR HARNESS. *NM

200 JEEP WRANGLER - MELTING HVAC WIRE CONNECTOR (3 WIRE CONNECTOR) ON SWITCH PANEL CAUSES THE FAN SWITCH TO SHORT OUT (MELT CONTACTS). MELTING PLASTIC SMELL FILLS THE PASSENGER COMPARTMENT. *NM

JEEP BLOWER MOTOR SPEED SWITCH STOPPED WORKING. UPON FURTHER INVESTIGATION AND REMOVAL UNDER DASH, A/C HEATER CONTROL CONNECTOR #3 AND A/C HEATER CONTROL UNIT SWITCH WERE BOTH MELTED. REPLACED THE UNIT AND BLOWER MOTOR RESISTOR. BLOWER MOTOR AGAIN STOPPED WORKING 1 YEAR LATER. REMOVED THE A/C HEATER CONTROL UNIT. BOTH THE A/C HEATER CONTROL CONNECTOR #1 AND A/C HEATER CONTROL UNIT POINT FOR THAT CONNECTOR WERE MELTED. *JB

I HAVE HAD THIS PROBLEM 3 TIMES WITH MY VEHICLE NOW. THE VEHICLE WAS HAVING HEATER PROBLEMS ON HIGHEST AND SECOND HIGHEST SPEEDS. TOOK THE JEEP TO THE DEALERSHIP AND PAID DEDUCTABLE ON THE SERVICE CONTRACT IN OCTOBER 2002. DEALER REPLACED THE UNDER DASH HARNESS, BLOWER MOTOR AND THE BLOWER MOTOR RESISTOR. I CONTINUED TO HAVE PROBLEMS AND TOOK IT TO MY PERSONAL MECHANIC THAT DISCOVERED THAT THE HEATER CONTROL MODULE HAD FAILLED AS WELL. HE REPLACED THE HEATER CONTROL MODULE AND JEEP WORKED FINE FOR 1 YEAR. THE HEATER BEGAN TO HAVE THE SAME PROBLEMS AGAIN AND MY PERSONAL MECHANIC REPLACED THE BLOWER MOTOR, BLOWER MOTOR RESISTOR AND THE HEATER CONTROL UNIT AS WELL AS REPLACING A BURNT WIRE. THE HEATER AGAIN LASTED JUST OVER A YEAR BEFORE ACTUALLY CATCHING FIRE UNDER THE DASH. THE ENTIRE UNDER DASH HARNESS, BLOWER MOTOR, BLOWER MOTOR RESISTOR AND HEATER CONTROL UNIT WERE AGAIN REPLACED. NO ADDITIONAL PROBLEMS WITHIN THE PAST WEEK AFTER RECEIVING THE JEEP FROM THE SHOP.*AK

WHILE VEHICLE WAS PARKED AND WITHOUT WARNING CONSUMER SAW SMOKE UNDER HOOD. LIFTED HOOD AND SAW A FIRE ON TOP OF ENGINE. DEALER WAS NOTIFIED .MECHANIC KEPT VEHICLE FOR ABOUT 5 DAYS; HOWEVER, WAS UNABLE TO REPAIR VEHICLE.*AK

WHILE VEHICLE WAS PARKED AND WITHOUT WARNING IT CAUGHT ON FIRE. THIS WAS THE SECOND JEEP, WRANGLER THAT HAD CAUGHT ON FIRE. VEHICLE WAS TOTALED. *AK

THE CONSUMER SMELLED LED BURNING/ PLASTIC PRIOR TO STOPPIN, THE FIRE ORIGINATED IN THE POWER DISTRIBUTION BOX. CLAIM NUMBER 17-9135-135. *YH

AN UNDER HOOD FIRE WHILE TRAVELING. VEHICLE AT DEALER FOR INSPECTION. CAUSES HAVE NOT BEEN DETERMINED AT THIS TIME. PLEASE FEEL FREE TO PROVIDE ANY FURTHER DETAILS ON THIS MATTER. *AK

WHILE THE VEHICLE WAS PARKED, THE HORN SOUNDED ON ITS OWN ACCORD, AND CONTINUED FOR OVER 6 HOURS UNTIL THE BATTERY RAN DOWN. WHEN I JUMP STARTED THE VEHICLE, THE HORN STARTED AGAIN, THEN STOPPED. SEVERAL MILES LATER, IT WENT OFF AGAIN, AND DIDN'T STOP UNTIL I DISCONNECTED IT. THE JEEP REPAIR TELLS ME THAT THERE IS A NATIONAL BACK ORDER ON THIS PART. DOESN'T THAT WARRANT A RECALL?*AK

UPON STARTING OF VEHICLE AFTER FUELING A 'POP' WAS HEARD FROM THE ENGINE COMPARTMENT AND ENGINE STALLED. RESTARTED ENGINE WITH NO DIFFICULTY AND ENCOUNTERED A HIGH IDLE SPEED. CHECKED TO SEE IF LINKAGE WAS SOMEHOW BINDING OR IF VEHICLE HAD BACKFIRED THROUGH THE THROTTLE BODY. NO EVIDENCE OF DAMAGE DUE TO BACKFIRE SO PROCEEDED TO DRIVE VEHICLE. AFTER TRAVELING APPROXIMATELY 40 MILES OF HIGHWAY ENCOUNTERED A STOP LIGHT, APPLIED BRAKES TO FIND THAT THERE WERE NONE. AT THAT POINT REALIZED THAT THE SOUND HEARD UPON STARTING WAS THAT OF THE VACUUM BOOSTER HOSE SEPERATING FROM THE MANIFOLD. NOTED THAT NEITHER HOSE INSTALLED AT THIS POINT ARE SECURED WITH A HOSE CLAMP. REINSTALLED HOSE AND HAVE HAD NO FURTHER OCCURRENCE.*AK
