Electrical: Headlights, Dash Lights Flicker; All Gauges to Zero

Exterior and interior lights have begun to flicker periodically, dimming and brightening, and in one episode the entire dash (all gauges) went to zeros and the lights went out completely, albeit for a brief second. This is not good!

Charging system checks out o.k. Battery is new as of 6 weeks ago (due to the same issue others have had with the battery suddenly dying). Anyone else experiencing similar issues?

    My car does the same thing. It corrects itself but usually starts again after a hard rain. Sometimes the check engine light comes on but goes off when I turn off the car and then restart it. My brotherinlaw has the same problem with his 500

Don't overlook a loose connection in the wiring harness. Since the entire dashboard goes out, the plug on the harness may not be all the way in to make a good connection. I don't think that everything would go through 1 fuse. Some of the Dodge's used to have a master thermal fuse. This would kill power to almost everything when over amp'ed or ever heated. Good Luck

SOURCE: check gauges light comes on

The PCM has the voltage regulator inside it that controls the charge from the alternator to the battery, unlike older vehicles that have the voltage regulator directly on the alternator. Also there is a battery temperature sensor under the battery that the PCM uses to decide how much to send the battery. Possibilities; bad alternator, bad PCM, bad battery temp sensor, bad battery, and bad connections. Battery tests are easy check when fully charged should get around 12.5v then turn on headlights for 2 minutes and check again should still be around 12v. To test charging system start engine and test at bettery terminals should get 13-15v if not then something wrong with charging system take alternator to advance auto and they will test it for free if its good you are down to connections, PCM and battery temp sensor. test battery temp sensor at 75 to 80 degrees fahrenheit should get 9000-12000 ohms resistance (9k-12K ohms) if thats good check ground connections on vehicle body , connections on alternator, and plugs into pcm as well as the two above it (depending on model and year). If all that is good your PCM is bad get one on the internet preprogrammed for your vin number for $250 if you get one at the parts store it is $250 and then you have to get it programmed about another $80. You can also test the alternator your self by disconnecting the 3 tiny nuts and removing the connection from the field terminals (plastic piece with two terminals) and checking again at battery for 13-15v ( stay away from pulleys and belt,no loose clothing or long hair if you value your health). The PCM shorts the field connectors to regulate the voltage so removing that connector eliminates the PCM , battery temp sensor and the wire to and from them.

sounds like a spike to the cluster caused this so i would suspect a faulty cluster assy

Need to replace the bearing on the passenger side front end assembly. Was told that I needed to have it pressed in by a machine. Can I do this myself with wood and a rubber mallet?

Dash lights come on with the headlights then shut off

Do you have a dimmer for interior lamps? Like a rheostat, a little wheel that you turn up or down to brighten or dim interior lamps. Usually the instrument cluster lamps brighten and dim the same way.
Can you brighten and dim the other interior lamps?

Why are my interior and exterior light flickering and diming .

Most likely the earth connection. Check all earth wiring, first and foremost check if the lights are powered from the same fuse! If that is the case remove the fuse, clean all contacts and replace with a new fuse! Happy motoring.

I changed the stereo in my 1993 pajero now the dash and parking lights don't work what could this be

To start, a fuse. The radio receives a signal or feed from the interior lights so that it will dim or brighten with the interior and dash lights. during the radio installation it may be that this wire was left off and not insulated, or used as a power lead, etc.

Start by checking your fuses, the interior dash lights and exterior marker lights are on the same fuse, so start by finding a burned fuse, replace it with same size, and then do this: Without turning the key on at all, try your lights and see if they work... if they do not, and the fuse blows immediately, that wire is shorted to ground, either touching a metal part of the inner dash or hard-wired incorrectly to the radio. It may be that it was mistaken as a ground wire during the change-out.

If after replacing the fuse, the lights come on, then turn the radio on and see if it blows. Whether it does nor not, the first place to check is the last place changes were made. If you return to check the wiring to the radio and cannot find the problem, disconnect the radio entirely, turn the lights on with a good fuse in place, then reconnect the wires one by one, keeping an eye on the lights, when they go off (fuse blows), that is the wire that is either mis-assigned or can be left off. Most newer radios are all led and it is not necessary to send a signal to it from the lights. Good Luck!

Lights dim while driving

Have your charging system checked. I had a similar problem with a chrysler van - the lights would brighten and then dim periodically. it turned out to be the battery.
