Question about 2003 Chevrolet Impala

Open Question

2003 Impala- dash and head lights flicker, clicking noise

After car has be running for about 1/2 hour, lights will flicker about every 30 seconds to 1 minute and horn will beep very briefly about every 2 minutes or so.
When this starts, a clicking sound is heard coming from the passenger side under or behind the dashboard. Sounds like a relay or solenoid clicking on and off.

    The problem seems to start after the car has run for a little while, then becomes constant, even after the car is shut off for a while.
    Last night I noticed when walking out to the car after it had been shut off for about a half hour, I hit the rermote switch to unlock the doors, the lights (head & backup) come on and they were blinking without the car being started. The blinking of flicker is very suddle/quick.
    I haven't notice the battery gauge doing anything out of the ordinary.

    When this happens what do the battery gauge say? When running and lights flicker, usually the diode in the alt. stops working. Might want to get it checked.

SOURCE: headlights flicker all the time

Hi, my name is ricky and im 24 yrs old and from Bronx, N.Y . I bought my 03 impala in 04 and i had the same problem in 2007 in which that clicking noise happens. The headlights flicker, and even the gauges inside the car would flicker at times. It has nothing to do with fuses or a relay, please dont spend money on that b.s. like i did..lol I will try my best to explain what i did so that you can save some money and time. READ EVERYTHING AND USE ADVICE AT YOUR OWN RISK.
1st of all - I went to a junk yard/auto salvage yard to find a USED part that i needed. Often there are good parts from cars that have been totalled.
2nd- What i asked for was a Body Control Module. This controls most of the electric issues you are having and costed me about 50 dollars compared to a new one that was over $200 and reached up to $500.
3rd- I went head first under the steering column and found where the BCM was located. Poke around to find it cause it is def. there, hidden well. It doesnt take special skill to remove it or find it.
4th-Replace the BCM, but be advised that after you do this, your car might not crank over.My car did crank over because i installed a automatic starter previously so i could have started it with the remote start.
5th- you MUST take the car to a chevy shop so they can Program your car to the body control module this costed me about $250.
All together this information has to help you in someway.
If you have further questions or would like to make a comment, then e-mail me at " gyalflexfameh@gmail.com "
I hope this helps...im not saying it is a 100 percent guarantee for you, but i had this same problem recently and this was the answer to my problem. By the way, never buy a american car again or a GM product for that matter...Kudos

I have a 98 Nissan altima gxe and my alarm won't honk when I lock the car but the lights go off when I lock it and Wen I take the alarm off no honk or lights go off Wat can I do


holdboth the lock and unlosk buttons on your remote simultaneously for about five seconds until the lights flash and horn chirps.that should do it.if not i believe these models used a separate horn for security system.possibly fuse for this horn is bad or the horn itself is bad.to see if this horn works lower drivers window.stand outside vehicle and lock doors with remote.wait about a minute and reach in window and MANUALLY unlock and open door(do not use power door lock button)this should cause the system to activate...horn should beep and headlamps should flash.if horn beeps try my first suggestion.if it doesnt beep and just the head lamps flash check fuses and horn for security system.

2000 Honda Odyssey. The passenger side headlamp burned out and I replaced it, no issues two days ago. Battery was cranking slowly and terminals were corroded so I cleaned them. Last night in 15 degree...


The driver's Multiplex Control System is a small computer that controls (among many other things) the dash lights brightness, ignition key interlock, shift interlock, and has a tie in to the brake light system and horn relay. It may be that this small computer malfunctioned and started the whole problem chain.

However, I note from the factory shop manual that if polarity is reversed on the shift interlock--it can be damaged. Reverse polarity will ruin the diode inside the shift interlock. This could have happened when you jumped the battery--a brief period of getting the cables and terminals mixed up could have done it.

Checking the shift lock solenoid can be done by removing the steering column upper cover. Disconnect the shift lock solenoid connector (2 terminals). Using long jumper wires, apply battery voltage to terminal 1 (yellow wire side) of the solenoid and ground terminal 2 (green wire side). Check that the shift lever can now be moved out of Park. NOTE: applying voltage in the opposite direction of that above will damage the diode in the solenoid and will probably ruin it. Remove your jumpers and shift back to park and check that the solenoid locks. If the solenoid does not work properly, it will need to be replaced. This involves removing the end of the transmission shift cable and is a complex job. Remember, no power to the solenoid equals a locked solenoid--it takes power to unlock it.

The Multiplex Control Unit has a self diagnostic feature which checks the computer itself and inputs to the computer. The computer check is called mode 1 and the input test is mode 2. The diagnostic trouble codes are outputted to the ignition key light and beeper.

To test, first confirm that all fuses are good, especially fuse 9 (10A) in the driver's under dash fuse box (left kick panel) and fuse 13 (7.5A) in the passenger's under dash fuse box (right kick panel). Then use a jumper wire (a wire with small alligator clips on each end works best) to jump the two leads of the multiplex test connector. (This is a light green 2 terminal connector dangling from the same wire bundle as the brake pedal switch connector.) Buckle the driver's seat belt (avoids nuisance beeps). Now turn the ignition switch to on. After about 5 seconds, the ignition key light should come on and the beeper should beep for 2 seconds then stop for .2 sec. then beep once for .2 seconds. This indicates that the system is in diagnostic mode 1.

If no diagnostic trouble codes (DTC's) are present, the key light and beeper will not blink/beep again. If there are codes: about one second after entering mode 1, the key light and beeper will indicate the DTC and repeat it every 3 seconds. If there are more than one, the system will indicate them in ascending order. The codes will be a light flash and beep so you will have to count the flashes/beeps to keep track. The codes range from 1 to 6. Code 3 (three flashes/beeps) indicates a problem with the multiplex control unit itself. Write back here for other codes or for questions about mode 2.

Hi, I have a check front tire pressure warning on my 2009 saturn vue hybrid I filled up the tire it's not low at all, how do I get rid of the indicator warning? Thanks Amanda


The TPMS light (Tire Pressure Monitoring System) for that vehicle should function as follows.

If the light is on and steady, it means that the pressure in one or more of the tires is too low, and if the light is flashing, then it indicates that one or more of the tires are over-inflated.

1. Turn the ignition key to the "On" or "Run" position but do not start the vehicle. (If the vehicle has an electronic keyless ignition then place the ignition switch in the "ACCY" position)

2. Press the "Lock" and "Unlock" buttons at the same time on the vehicles remote key fob, and keep holding the two buttons down until you hear the horn beep, and usually this takes around five seconds. The horn beep will indicate that the learn cycle has begun.

3. Re-learn the TPMS system. Deflate or inflate air into the driver-side front tire for approximately 8 to 10 seconds and then listen for the horn to beep one time. (the horn might beep before the 8 to 10 second re-learn, or it could even take as long as 30 seconds after)

4. Repeat steps 2 and 3 for the remaining three tires. Also, the remaining three tires must be checked in the exact following order, the passenger-side front tire, the passenger-side rear tire and finally the driver-side rear tire. After the final TPMS sensor has re-learned then the horn will beep twice.

5. Listen for the horn to beep twice. When the horn does beep twice, it wikll be the indicator that the TPMS system has re-learned and reset.

6. Turn the ignition switch to the "Off" position, and then be certain that all four tires have the correct tire pressure as recommended on the drivers door, and the next time that the ignition is turned on, the tire pressure light should be reset.

Let me know if you require any further assistance.

I have a 1998 Chev Tahoe and I'm replacing the keylock cylinder. I'll prob have a prob. with the passlock system. How do I program the key to work?


Well, this is how it's supposed to work but I have had to resort to using a GM specific scan tool when I couldn't get it to relearn.
1. With vehicle in Park, turn the key to the crank position briefly [do not start engine but just bump the starter so the engine turns over about 1/2 a turn] then release the key and let it remain in the "run" position. The security light should flash for a few seconds then stay on for about 10 minutes.
2. At the end of about 10 minutes, the security lights should go off so watch closely. Once it goes off turn the ignition key "off" for about 10 seconds then repeat step 1 two more times which should add up to about 30 minutes total of time spent.
3. After you have finished the 3rd of the 10 minute cycles, leave the key off for about 20 seconds then try and start the engine. If it starts...you should be ready to go. If not, then you may need to have someone with a scan tool help you out. Like I say, it SHOULD work but I have found some aftermarket key cylinders that I just can't get to relearn so you may need an OEM cylinder [I would suggest it actually]
Good luck, hope this helps you out.

94 golf iii makes a beeping sound after it has been driven for 1/2 hour. can't tell if a light is flashing as my dash light is out. The beeping sometimes will continue for 5-10 minutes then stop for 1...


Bring this vehicle into a shop as soon as possible. The beeping noise may be your oil pressure switch telling you there is a problem. Pretty soon the vehicle may not start. I'm not sure if this sensor is tied into ignition system.

go to a shop and see if there is a code stored in memory. anything else would just be a blind guess. If you are near an Autozone that do a scan for free
