Analog Clock Lights Flickering - Repaired!

I know there have been several threads on the flickering light surrounding the analog clock and how it eventually fades to off.

This happened to me the other day, and it has been driving me crazy. Everything I read said that the clock (about $300 or more, depending...) had to be replaced and that it wasn't repairable. That didn't make sense to me, so I took the plunge and disassembled the whole thing.

I don't have a "write-up", per se, but I took photos along the way and I have a video showing the before as well as one showing the after.

There are already a couple of videos demonstrating how to remove the center console and gain access to the clock, so I will forego that explanation and just move on to the photos and video links.

Once the console has been removed, you will need to remove the clock itself from the console.

In order to remove the clock you must first remove the four screws in the corners that attach the circuit board backer to the console.

Remove these four screws as well...

And finally this one and the one attaching the white portion of the platform of the Passenger Airbag light. These screws are longer than all the rest and attach the backer board through to the front part of the console.

Once the clock unit is out, remove the bezel, buttons, and clear plastic clock protector and set them aside.

Here is what you have left...

You must gently remove the big, then little hand by prying upwards. The clock hands are attached only by friction. Here, the minute hand has been removed while the hour hand has not.

Pry here to remove the clock face and face housing (clear plastic) after removing the hands.

Here is what you have now...

Gently pry the white tabs that secure the TOP half of the circuit board away from the board, then you cam pull the board up and out, wiggling it a bit to free it from the four spring-loaded pins in the housing.


On the circuit board, you can see LED1 and LED2. Chances are that one of the solder joints has been compromised and is no longer making a good connection. I recommend adding a touch of solder to each of the connections and seeing if that does the trick.

LEDs are diodes, which means they allow electricity to flow in only one direction. These LEDs are connected IN SERIES, so if one of them is bad then the other one CANNOT light up either, since the circuit will be interrupted. Using another surface mount LED, I was able to touch the contacts of LED2 and complete the circuit, which is how I discovered that the LEDs were NOT actually burnt out. I immediately added a touch of solder to each contact and the repair was complete.

Here is a video of the before:

And here is after:

Best of luck!

Thanks! I'll keep this in mind if it ever happens to me.

Great post. Same exact issue with mine. Soldered the right side of LED2 and all was fine. I went a bridge too far, though and preemptively went to do LED 1 and damaged the LED....I'd not make a good brain surgeon. Will need to cough up $300 for a new clock now. Lesson: quit while you are ahead, lol.

Search eBay for infiniti g37 audio control (or similar) and get a used clock. I've done it 3 times and have only spent $150.

Ebay like the other person said, or if you can find a G in a wrecker I don't imagine they'd charge much for the clock.

Thank so much for the info, I just fixed my flickering clock in the exact same way! I didn't even take the clock hands or face off, as I was able to angle-in from the side to reach LED2's legs. THANK YOU!

Mine issue was the LED1, not LED2. After I soldered it, the light completely stopped working. Is it also right side of LED1?
Must to say, not working LEDs are much better than flickering ones

Same thing happened to me.
I bridged the grounds on LED1 and now dont have lights at all. I tried to reverse it using copper wick, but still no lights.

Oh well, at least i dont have to cover up the flickering clock with gas coupons anymore.

Hey everyone, this is a useful thread, I disassembled the clock, but I have no soldering skills, took it to an experte.. determined 1 LED was bad, so I tried to search locally for a LED (Panama) with no luck. I ended up ordering this in EBAY: "LED PLCC4 1210 3528 Cool Clear White". Cost only 5 bucks, so if this corrects my issue, it definitely better than buying a new one
