Silverado :: Instrument Cluster And Radio Lights Flickering / Surging
Jan 16, 2013
I have a 99 silverado, 5.3l Z71. This morning got in my truck, it started up fine, I then noticed instrument cluster and radio lights were flickering/surging but voltage was at 14v. Put it in reverse and the voltage dopped to about 12/13v like it was about to die gave it gas and it shot back up to normal. So I'm driving and everything electrical goes out and comes back on. Battery flashes, security light flashes, abs brakes come on and off, gauges fluctuate. And noticed it was doing it every 4 seconds. Radio doesnt stay on after i turn the truck off either as it normally does. Doesn't do any of that while sitting idle only while driving and my truck never actually stops running which doesn't make me think alternator is going bad.

The instrument cluster in my 2000 Silverado 1500 recently stopped working. All the gauges are flush to the left, except for the oil and battery which stay about in the middle. I ordered a different cluster online and went to install it today, finding that it still doesnt work. Except in this one everything aside from battery and oil are flush to the right. What to try next or am I going to need to take it in?

2011 Silverado instrument panel dimmer won't reduce below about (subjectively) 40% intensity and cannot be turned off - still way to bright for old eyes on dark mountain roads. Dealer says its characteristic of the model and has no suggestions. Scan-tool results for dimmer potentiometer output reads 2.7 volts (9%) at minimum rotation, and 3 volts (100%) at max intensity. Scan-tool results for LED PWM drive signal reads 0% at minimum and 100% at max. The pulse width modulator (PWM) appears to be an imbedded component of the body control module (BCM) so is not accessible. The dimmer potentiometer is a component part of the headlights combo switch so is likewise not directly accessible.
Since I can't get to the potentiometer voltage divider circuit, if I add a fixed resistor to the output leg of the potentiometer and reduce the dimmer signal voltage by another 0.1 volt (to 2.6 volts out to BCM/PWM) will I set a BCM DTC or raise the voltage on the LED drive pulse to a damaging level? Alternatively, if I place a spst switch in the dimmer output signal, will the PWM simply switch off, or try to further decrease the drive pulse width? Last shot-in-the-dark question before I drag a scope out and start tapping into wires, how to find out what IC chip is used in the PWM?

I have a 2005 F 350 with a 6.0 Diesel! My heat quit on my wife and I the other night! I replaced some fuses and started the truck to make sure the heat was working and it was! So I thought while I am here I should replace some bulbs in the cluster that were out!
I took the cluster out, looked at the bulbs and they looked oK so I put them back in and put the dash back together! When I went to start the truck once I turned the switch on my gauges and lights started flickering on and off fast and all it will do is just click when I try to start it! I just had it running 15 minutes before this!
I went through all the fuses and if I take one of the relays out and turn the switch on all the lights and gauges seem to work right but when I try to start it, nothing! I replaced the relay and it starts flickering again! I had the relay checked at Napa and they said it was good! The relay was for the Powertrain module!

Last Thrusday, my wife couldn't start my Sonata 2010 with 30,350 miles on it. It just clicked and sounded like a dead battery. She had to get a jump start through Hyundai road side service.
I change the battery yesterday (it only had 225 cranking amps) and immediately strange things started happening: lights flickering, engine surging, hard starting, not starting just clicking, gauge lights blink strangely at startup and when switching off ignition, not remembering odometer settings (I set my odo for MPG).

These last few days I've been having issues at startup. Ill put the key into the ignition and it will just click once or twice without anything happening. Power to the radio and instrument cluster will get distributed but the engine wont turn. Then the other day the engine would turn on for a brief moment but turn off within ten seconds. Whats going on?

Need to know if the little icons on your interior 'dome' lights illuminate red when your instrument cluster lights are on? (Just like the power window and dash vent icons..) Audis do, but I've never seen a W8 Passat at night to be able to tell.
Looking for a pic of your interior roof lighting? (Not the center console one near the sunroof control...that of course lights up and shows icons.) I'm looking for the ones towards the rear of the car.

99 F-150 V-6, 125,000 miles: I repaired the odometer connection on the cluster mother board! It now works great but now have no running (parking) lights and no backlights for the instrument cluster. I think (!) they were working before I pulled the cluster to fix the odometer--not sure. Fuzes are all good--I metered each with ohmmeter for continuity, and also have 12V to the right fuzes with headlite switch in Park and Head. I replaced the headlight switch with a new one but still the same problem. Have I messed up something in the cluster board or connections by soldering there? I don't know what role the cluster plays in feeding the running lites or the cluster backup lites. Stumped. What am I missing?

Turned my lights on in my 2001 VW Passat and my instrument cluster lights are no longer working. The area showing MPG and Outside temp is functional but nothing else is. The lights for the radio, fan hazard sign etc are all fine.

On my 2002 Santa Fe I just noticed that the instrument lights on the dashboard are out. Also the ones that show the shift position do not work when you put the parking lights or headlights on except R lights up. I have checked about 10 different fuses, but they are all good. All exterior lights and turn signals work.

I just bought this 2006 f350 lariat. The instrument cluster, radio, pwr windows (and prob other things) will go dead intermittently. No rime or reason, some days no prob, others, several time a day. Always come back by itself, cycling the power has no effect. I if it is shut down during a no power episode it will not run right till the power comes back to the dash, radio, windows. Looking on line seems to be a common problem with the "retained power accessory relay" circuit in the instrument cluster. I found nothing on a DIY fix...

Today I had the joy of covering 200+ miles on my W12 today. While I was out and about there were 3-4 times I went around a right hand turn somewhat quickly and a "check please lights" warning appeared on the instrument cluster. At the end of the day I inspected the exterior lights with all working or so it seems. I found it odd that this only appeared during sharp turns to the right.

I have a 2007 Santa Fe. I was at a drive thru when my instrument cluster started to go nuts.. all of the lights came on then started flashing.. the RPM gauge was bumping around too.. for a couple seconds.. then it went away.. the next day I was on the way home and it started to do the same thing as the motor began to lose power while climbing a hill then the transmission couldn't figure out which gear it wanted to be in then I could press the gas all the way but nothing would happen.. the battery was completely dead. so I replaced the battery an about a week later it did the same thing. I had the alternator checked out but it was fine..

I have 87 Ford Ranger. 2.9L 4x4. Before any tips, I have checked the fuses, I have changed the Switch for the lights and the instrument cluster. Still no luck. I don't know if there is something wrong with the wiring. But what I was plan on doing is finding out on one of the Wiring Harnesses on the back of the Cluster which wire turns on the back lights on the cluster. Everything else on the cluster works (Gauges, Highbeam indicator, all the warning sign lights). What wires are what on the wiring harnesses. I was going to just run the wire to its own switch.

One of my bulbs sometimes doesn't come on when I turn my lights on. I actually have to hit the dashboard to get it to come on. Does it randomly. Ironically, it's been doing this ever since I pulled the instrument cluster out to change a different bulb. I don't know if I did something when taking it out or putting it back in. Anyway, what I can check to see why it's doing this? It's just one bulb that illuminates the right portion of the tachometer.

Just the other day I fired the truck up and turned the lights on and my headlights came on but my gauges didn't light up. I figured I probably had a blown fuse or something so I didn't bother checking it immediately and decided to drive home anyways and on the way home I got a phone call saying that my running lights weren't working either. Front or rear. Still have brake lights and turn signals but no running lights. I've checked all the fuses and none of them are blown and I'm going nuts trying to figure out what is wrong before I get a ticket. I'm tired of lightly holding the brake as I pass by cops at night. What could be causing this issue?

Here's the problem, when the high beams are on the dash cluster lights work fine,but when I turn the high beams off the dash cluster lights go off.Im going to buy a new high beam switch but what else might cause this problem?The truck has one of those metal button high beam switches that is mounted on the floor.

Disclaimer: When I refer to lights, I mean the back-lit radio controls.
Noticed they're lights flicker when they turn off the car? It doesn't happen all the time and just kinda weird.
I have a 2014.5 SE Sport and the only thing I can think of is I always have my parking lights on (cuz I turned off DRL) but they always turn off when I open my car. Each time I try to record it, it stops doing it. It usually only last for a few seconds but just thought it to be odd.

I have a 2008 Ford F-150 xlt with stock instrument cluster. I need a new instrument cluster due to my interior lights coming on while driving. I would like to make it look better and not go stock. Id like to have digital shift screen and good looking LED's. What all are my options?

I have a 2001 F350 and instrument cluster lights will not work. Fuses are good and the gauges still work just not the lights.

I have a 1997 Ford Expedition, 5.4. My research indicates that fuses 2. 19. 29 are associated with the instrument cluster (IC), could you identify their specific function in relation to the IC? My IC gauge lights are not showing and my alternator is not consistently charging. The blinkers, battery, oil, brake, and ABS indicator lights are showing in start. Regarding the alternator, my research indicates that a failing alt light on the IC may cause the no charging condition? As a note, I have a brand new battery, brand new alternator, brand new 3 pin wiring harness. Also, when the alternator is not charging and I connect the a jumper from the exciter wire directly to the pos battery terminal, the charging starts.
