Tl* the contact owns a 2002 Chevrolet Monte Carlo. The contact stated that the head lamp lenses had been oxidized and that there was a film build up which affected the visibility of the low beams while the vehicle was in motion causing the lighting to be dim. The contact also stated that the key less entry function failed intermittently and that upon entering the vehicle, it would not start. The contact was able to utilize the owners manual to override the system by either disconnecting and reconnecting the battery cable or resetting the computer. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The VIN was not available. The approximate failure mileage was 2,400.
Turn signals fail to work and headlights go off when you are driving on interstate or local roads. Sometimes the headlights will come back on in a few seconds, other times it takes as long as thirty seconds
Turn signal failure: beginning in 2005 through to 2007 the turn signals would work intermittently. While under warranty the vehicle was taken to the dealership. They indicated that there was no problem. Once warranty was expired there was nothing I could do. I did find that turning the hazard signals on for 5-10 seconds would sometimes correct the problem and the turn signal would work. Finally after many hours searching the internet I found several postings indicating that there was a faulty hazard light switch, the turn signals are also controlled by the hazard light switch. In October 2007 I spent $399 to have the hazard light switch repaired. Please insist that the dealership replace the hazard light switch and not add on additional parts like the turn signal arm etc. My dealership first quoted me $850 stating that the turn signal arm must also be replaced to correct the issue. …
I have a 2002 Chevrolet Monte Carlo ls. About 1 year ago my turn signals quit working randomly. It seemed to be the worst on hot days. I would leave my home or work with them working properly and then at a random point during my drive they would no longer work. GM has recalled other makes and models for similar problems. However, the Monte carlos have never been recalled. After searching for a potential solution to this problem, I have found that it seems to be a very common problem on many similar cars that GM makes. Most people have said that it is related to the hazard switch in the dash board. This is a relatively cheap fix however it is also a major safety hazard since I never know when the turn signals will or will not work. It seems to be luck of the draw, which is very dangerous. Thank you for your consideration on this problem.
On my way to work on my normal route before dawn, driving down a narrow curvy rural road rife with deer, I flicked on my high beams as usual. About 5 seconds later I lost all my headlights. Somehow safely pulled off road without falling into the ditch and turned off vehicle. After several minutes of turning lights on and off the fog lamps came on and I was able to make it back home very slowly. Spent $1000 getting a control module replaced. Had trouble with turn signals quitting randomly for 3 years, have to turn on emergency flashers in order to get them to work. Another $500 will fix the problem but since the car is only worth $1500 it doesn't seem worth it. This car is a piece of junk - 2 transmissions, numerous electrical problems, 5 steering shaft replacements...
My 2002 Chevy Monte Carlo has been experiencing electrical problems since I have owned it. The cruise control comes on without being selected and then the heating/cooling systems goes off and on by itself. The turn signal goes on and off. Sometimes it will work sometimes it will not. The fuel gauge does not register correctly goes up and down so I am never sure what is in the tank. Occasionally the car will not start at all even though the lights work, the radio plays, and everything else will operate inside the car. I will sit and wait a while. After about 15-25 minutes I will try to start it and then it will start up. This has been happening more and more. I have talked to other Chevy Monte Carlo owner and they have had the same problems with their car.
When I turn on the blinkers sometimes they work and sometimes they don't. When they don't no light comes on at all ( no blinker on the dashboard or on the outside lights). On numerous occasions my life flashed before my eyes when I was nearly struck by other vehicles while trying to make a turn and my turn signals weren't operating properly. I went to an auto parts store and they stated that the problem was a common one. They stated that it was the flasher assembly (in the steering column) costs $ 299.00. I feel this issue should be looked into . I am a police officer and if I didn't have this issue with my own vehicle I wouldn't have believed anyone else's story. Please contact me by phone or e-mail thank you rich.
Turn signals will not always work. Replaced the hazard/signal switch located behind the dash only to have the same problem. Pressing on the dash near the hazard switch or pressing the hazard switch will return signal to normal operation for a short time. While I was replacing the original, I noticed placing a very slight pressure on the switch assembly will cause the signal to either stop or start working. I believe the problem is with both the switch design as well as the dashboard design. Hot/humid weather appears to irritate the situation causing failure more often. Researching the problem via web searches finds many owners with the same problem. This problem also seems to be common to many GM model cars.
Sealed beam headlight assemblies gradual internal moisture build-up till condensation on the lenses get trapped on inside surface causing diffusing and diminishing front headlight transmission. Internal moisture that builds up over time and exposure to rain cannot be removed. Adds to risk of corrosion, electrical short, explosive pressure build-up when heated through use and total failure of headlight assemblies. Only remedy is model wide recall for safety inspection and replacement including inspection advisory to owner warning of potential problem and safety hazard. Manufacturer is reluctant to issue a recall due to the high cost of replacement headlight assemblies of over $250 each.
When my wife or I attempt to turn on the high beams in a poorly lit area/region the lights shut off completely. We almost entirely lost where we were on the road and had to slow down and make an abrupt stop. After playing with the switch for a couple moments we finally got the high beams on. Now, a car comes from the other side we attempt to power off the high beams and switch back to low beams and the car stays stuck with high beams on and we are now blinding on coming traffic. Fortunately there was no accident involved, however, either event could have easily LED to an accident especially if it were to happen in adverse weather. Please advise as this should be a recall.
