1998 Chevrolet Lumina problems

UNKNOWN OR OTHER

THIS PROBLEM EXISTS BWHEN THE VEHICLE IS SATIONARY AND IN TRANSIT. IT APPEARS TO BE INTERMITTEN AS WELL. MY BRAKE LIGHTS WORK WHEN I AM BRAKING, BUT THEY SEEM TO INTERMITTENLY BE FAILING WHEN I USE MY DIRECTIONAL SWITCH (4 WAY). I HAVE BEEN ADVISED ON 3 OCCASSIONS, TWICE BY SHERIFF'S DEPUTIES THAT MY BRAKE LIGHTS ARE NOT WORKING. BUT THEY DO WORK EXCEPT WHEN THE DIRECTIONALS ARE ON. AFTER SOME RESEARCH WE HAVE DISCOVERED THAT REPLACING THE 4 WAY SWITCH WILL RESOLVE THE PROBLEM. MAY I NOTE THAT I HAVE NEVER HAD THIS DEVICE FAIL IN ANY OF MY VEHICLES EVER. THAT REGARDLESS OF THE GES AND MAKES OF MY VEHICLCES THE MANUFACTURERS HAVE HAD THE GOOD SENSE TO MAKE CERTAIN THE 4 WAY SWITCH WAS RELIABLE. MIGHT I ADD LINKING BRAKING WITH THE SWITCH MIGHT BE CONSIDER IRRESPONSIBLE OF THE ENGINEERS. HAS THE 1998 CHEVY LUMINA 4WAY SWITCH BEEN RECALLED!?

I WAS FORCED TO DRIVE THIS COMPANY VEHICLE BY NEW TRANSPORTATION MANAGER, EVEN THOUGH I HAD ANOTHER COMPANY VEHICLE ASSIGNED TO ME TO DRIVE. FROM 11/9/2018 TO 11/13/2018 I WORKED OVERTIME PLUS MY REGULAR WEEK OF WORK. IT WAS THE FIRST TIME USING THE HEATER IN THIS VEHICLE AND I WAS WORKING LONG HOURS WITH THE HEATER ON BECAUSE THE WEATHER HAD CHANGED. ON 11/11/2018 AT ABOUT 0600, I STARTED HAVING A HEADACHE AND MY THROAT WAS IRRITATED BUT I WENT HOME AT 0800 AND CAME BACK TO WORK OVERTIME PLUS MY REGULAR SHIFT ON THE SAME DAY AT 2000. MY HEADACHE HAD INTENSIFIED AND I TOOK ALEVE FOR IT AND DRANK MILK FOR MY IRRITATED THROAT AND WEN HOME AT THE END OF MY SHIFT AT 0800 ON 11/13/2018. I WORKED THE REST OF THE WEEK BUT MY HEADACHES CONTINUED AND ON 11/19/2018, I ASKED THE MECHANIC TO SMELL THE CABIN OF MY VEHICLE AND AFTER SMELLING IT, HE TOLD ME TO PARK IT AND REPORT IT TO MY MANAGER BECAUSE IT HAD AN EXHAUST LEAK. ON 11/26/2018, I WENT TO THE HOSPITAL AND THE DOCTOR PLACED ME ON MODIFIED DUTY UNLESS I WAS NOT PROVIDED A DIFFERENT VEHICLE TO DRIVE AND THEN I WOULD CONSIDERED TEMPORARILY FULLY DISABLED UNTIL 12/14/2018. ON 11/28/2018, MY MANAGER TOLD ME I WAS GOING TO BE DRIVING THE DIRTY VEHICLE AFTER I HAD ASKED FOR ANOTHER VEHICLE. I HAD MY SUPERVISOR SMELL THE CABIN AND HE GAVE ME HIS TRUCK TO DRIVE AND I DROVE IT FOR 2 DAYS. ON 11/30/2018, MY SUPERVISOR TOLD ME THAT OUR MANAGER HAD CLEARED THE DIRTY VEHICLE AND I HAD TO GO BACK TO DRIVING IT BUT I WENT HOME FULLY DISABLED INSTEAD. ON 12/4/2018, I WAS FORCED BACK INTO WORK AND I DROVE MY MANAGERS TRUCK. ON 12/5/2018, I DROVE THE DIRTY VEHICLE TO THE FIRE STATION AND IT TESTED POSITIVE FOR AN EXHAUST LEAK WITH CARBON MONOXIDE IN THE CABIN. I HAD MY 2 DAYS OFF AND ON 11/8 AND 11/9/2018, I HAVE BEEN STAYING AT THE OFFICE BECAUSE THEY'RE FORCING ME TO DRIVE THE DIRTY VEHICLE AGAIN AND I CAN'T GO OUT TO WORK.

EXTERIOR LIGHTING

WE BOUGHT THE CAR USED. AT TIME OF PURCHASE BRAKE LIGHTS APPEARED TO WORK. SAME EVENING, THE TWO REAR/SIDE BRAKE LIGHTS DID NOT WORK (THE THIRD/MIDDLE LIGHT WORKS). WE DID SOME TROUBLE SHOOTING, REPLACED BULBS, CHECKED FOR SHORTS. IN OUR RESEARCH WE FOUND THAT THIS IS IN FACT A COMMON PROBLEM AMONG GM SEDANS AND IS CAUSED BY FAILURE OF THE MULTIFUNCTION SWITCH IN THE STEERING COLUMN. THE SWITCH CONTACTS COMMONLY FAIL WHEN THE SWITCH BEGINS TO LOOSEN/DISINTIGRATE. THIS CAUSES A VARIETY OF ISSUES AMONG THE SYSTEMS THAT PASS THROUGH THAT SWITCH. BRAKE LIGHT FAILURE IS ONE SUCH ISSUE, AND OBVIOUSLY A SAFETY ISSUES. YES, I KNOW IT'S AN OLD CAR AND YES I EXPECT TO HAVE TO MAKE REPAIRS TO IT, BUT I DO NOT EXPECT OUR STUDENT DRIVER TO SUDDENLY BE WITHOUT BRAKE LIGHTS BECAUSE OF THE FAULTY MANUFACTURE OF THIS COMPONENT. A SMALL AMOUNT OF RESEARCH MAKES IT APPARENT THAT THIS IS A VERY COMMON, VERY WIDESPREAD PROBLEM. IT'S EXPENSIVE TO FIX AND BEYOND MOST PEOPLE'S DIY ABILITIES, BESIDES WHICH I WOULD NOT BE COMFORTABLE WORKING WITH ANYTHING THAT AFFECTS THE AIRBAG SYSTEM. THERE IS ABSOLUTELY NO WAY GM HASN'T BEEN AWARE OF THIS ISSUE. I CAN'T UNDERSTAND WHY THERE'S NO RECALL FOR THIS ISSUE.

ENGINE

MY REPORT: ORIGINAL DIAGNOSTIC CODE WAS 3RD CYLINDER SPARK PLUG. SYMPTOMS WERE CONSISTENT WITH THIS. CAR DROVE FINE THAT EVENING UNTIL THE ENGINE HAD TROUBLE, SPUTTERED AND SHUT OFF. MECHANIC LOOKED AT IT AND DETERMINED THERE WAS NO COOLANT AND CAME TO THE CONCLUSION THAT THE ENGINE FAILED BECAUSE THIS MODEL AND YEAR IS KNOWN FOR COOLANT LEAK INTERNALLY BY INTAKE MANIFOLD GASKET. THERE WERE NO SIGNS OF COOLANT LEAK EXTERNALLY PRIOR TO THIS, DIDN'T BLOW WHITE SMOKE OUT THE BACK, THE LOW COOLANT LIGHT DIDN'T GO ON, THE OIL WAS FULL, NO MILKY STUFF IN RADIATOR EITHER, THE CAR DROVE LIKE NEW, AND THE CAR ONLY HAD 76,000 MILES ON IT. THE CAR HAD ONE PREVIOUS OWNER AND WAS WELL-MAINTAINED BY THAT OWNER AND MYSELF. I BOUGHT IT 2 YEARS AGO WITH ONLY 38,000 MILES ON IT. I LOOKED INTO WHY THE INTAKE MANIFOLD GASKET WOULD LEAK AND FOUND 2 REPORTS. BECAUSE THIS WAS A DEFECT, I SHOULD BE COMPENSATED WITH AND ENGINE OR MONEY FOR THE ENGINE FROM CHEVY: PROBLEM REPORTS: CHEVROLET LUMINA REPORT: INTAKE MANIFOLD GASKETS MAY LEAK COOLANT OR ENGINE OIL MODEL YEARS AFFECTED: 1994, 1995, 1996, 1997, 1998, 2000, 2001 ENGINES AFFECTED: 3.1L V6, 3.4L V6, 3.8L V6 THE INTAKE MANIFOLD GASKET MAY DEVELOP AND EXTERNAL ENGINE OIL OR COOLANT LEAK. IN SOME CASES, AN INTERNAL COOLANT LEAK MAY OCCUR CAUSING COOLANT TO MIX WITH THE ENGINE OIL. OUR TECHNICIANS TELL US THAT OPERATING THE ENGINE WITH A COOLANT/OIL MIX CAN RESULT IN INTERNAL ENGINE DAMAGE. REPLACING THE INTAKE MANIFOLD GASKET SHOULD CORRECT THESE LEAKS. UNFORTUNATELY THE 3.1 LITRE ENGINE HAS A MANUFACTURE FLAW. THE GASKET IS PLASTIC AND RUBBER. OVER TIME THE PLASTIC CRACKS DUE THE HEAT AND THE RUBBER SEAL FAILS. FELPRO HAS REDESIGNED THAT GASKET. INSTEAD OF BEING PLASTIC AND RUBBER IT IS STEEL AND RUBBER.
