Replying to: john_gilius (Sep 26, 2008 7:57 pm) If this is what you are experiencing, I would say it is normal (I have owned several cars that also exhibited this type of behavior). However, if your lighting is pulsating/dimming/flickering constantly while driving then that is a problem that the dealer should easily be able to resolve...especially if it is doing it when the radio, A/C system, rear defroster, turn signals, overhead lights, etc. are ALL OFF. That leans toward one of the underhood components putting an abnormal load on the electrical system...or shorting out. Do the lights flicker if you turn the headlights on manually using the headlight switch as opposed to the auto setting? If they do not flicker on the manual setting, it could be something as simple as a faulty auto-headlight switch or sensor. |

| hey ryster... i know when stuff like power windows are used there can be a dimming of the lights, but this is actually like a pulsing of the lighting system where the dimming is like going between say a 50 watt light to a 55 watt light and back again. it occurs randomly, and i compliment my wife on trying all different things as she's driving to isolate the source or cause of this. she did try the headlights manually to no avail. the car will be back to the dealer. i can't take the chance that the electrical system might end up funny because of this problem and have it bite me in the butt at 36,004 miles. i paid a bit more than i think i should have for a "certified" vehicle, but that was for peace of mind that the car is right. and right now.... it isn't totally right. any other suggestions are welcome. i get to drive the car after dark tonight, so i have a chance to check out a few things myself. | |

hey wbowl99, you were dead on, and when i did another online search for that TSB, i came across another forum http://www.automotiveforums.com/vbulletin/t880299.html that perfectly described the same problem as me, and the fix. armed with that, walked into my dealer today, they were impressed i found the problem, LOL i talked with the tech who replaced my alternator last week and he said that he never took it for another test drive at night with the car to verify he had fixed the problem. i told the tech i had told the service manager to keep the car for as long as it took to find the problem, glad he didn't. at first, he looked up TSB's on his computer for the 2007 impala, and it didn't show up. when we looked up the TSB number, there it was. the tech stated that he didn't find that TSB because it didn't show up under the impala category. odd. needless to say, he printed out the TSB and went right to the service manager with the information, the SM stated he'd get the parts located and delivered ASAP and that i can expect them to work on the car tomorrow. i will keep you all abreast. priggly, it appears as though this problem is confined to the 2007 impala and maybe the monte with the 3.9 V6, so hopefully i don't have a lemon. talk with you all soon. peace..... john

hello.. picked up a new keyless entry for the 07 impala, and in following the instructions for programming it to my car, i haven't beeen able to get out of the blocks yet. in looking at a few different sites, the basic conceptual procedure is the same. close doors, hold down unlock button on car door, turn key to on,off,on,off, release unlock button; then car will lock and unlock to show it is prograrm mode, then procede with the remotes. i have tried several times to do that part of the procedure to get the car to do the lock/unlock thing, but i am not sure if my timing on the ignition switch part is right. is it a quick onoffonoff or a on, off, on, off, or is it on...off....on....off? any tips are as always appreciated. peace.... john

To match a remote keyless entry transmitter to your vehicle, do the following: 1. Press the vehicle information button until PRESS V[checkmark button] TO RELEARN REMOTE KEY displays. 2. Press the set/reset button. The message REMOTE KEY LEARNING ACTIVE will display. 3. Press and hold the lock and unlock buttons on the first transmitter at the same time for approximately 15 seconds. A chime will sound indicating that the transmitter is matched. 4. To match additional transmitters at this time, repeat Step 3. Each vehicle can have a maximum of eight transmitters matched to it. 5. To exit the programming mode, you must cycle the key to OFF. |

wbowl, very funny that the stealership tried to make you feel as if you found priviledged information. you know, if it weren't for internet based forums like this, my bet is that my dealership would try to tell me there's nothing that can be done about my car. TSB's, i am willing to bet, can accumulate and become full blown recalls, and that hits the car maker's bottom line. i know my dealership didn't find the TSB pertaining to my car; i talked directly with the tech. it's my belief that a consumer has to be so savvy now, and information is power. i paid $17,000 for my car, and seeing as how it's CERTIFIED, which i PAID for, it damned well better be right. trust me, any information i turn up on this car through these forums will be scrutinized. i guess what ticks me off is that GM knows about the issue i am having, but figures it made a defective system that they don't have to fix unless the customer figures out that the system is defective. well, bottom line is the dealership called today and informed me the parts are in, and the car should be going in friday for the big fix. as always, i will keep you posted. thanks again for everyone's help. sincerely, john hutchison

Replying to: john_gilius (Oct 07, 2008 4:34 pm) There are a number of things GM knows about that they hope we will not report. If we don't, they're not going to admit it. I saw one TSB addressing a problem that actually said that if the owner didn't mention it they should not either because they didn't know what it was or how to fix it. It had to do with a noise in the rear passenger side that sounded like something had hit under the car. I had that happen numerous times for a couple of months, but then it disappeared and hasn't returned as yet. |
