99 Honda CRV Clock Fix

99 Honda CRV Clock Fix

Posted by on Dec 27, 2010 in Repair Procedures

My daughter’s 99 CRV needed a few interior dash light fixes. A little googling saved over $200 on a clock fix so I thought I’d post my repair procedures in the hope that it might help someone. These should be applicable to Honda CRV clocks from 1996 – 2001.

It took about an hour if you are comfortable with these sorts of things.  If you aren’t, then I’d suggest following the instructions at www.autoclockrepair.com and send your clock unit to them. They were helpful in providing the clock removal procedures that I followed.

This is what the clock unit looks like (Front and Back) after it is removed from the vent bezel assembly (click on photos for larger images):

In the second photo you can see the shape of the clips that hold the white back to the black front. Gently pry the white “loop” section over the black tab, just enough to clear the catch on the black tab. If you have three or four hands, you could simultaneously gently depress the black tab. The photo below shows the clock unit opened:

The arrows are pointing to the buttons to set the clock. Be aware that these plastic parts will slide out easily so don’t lose track of them. With your attention to the circuit board, you can see below that the green board is held to the white case by two clips (circled below).

Gently pry those away just enough to free the circuit board below. After you free the two clips, pull the circuit board apart carefully as the four pins that stick out the back of the unit still need to clear the white housing.

After this it is a matter of identifying what went wrong on the circuit board. In other posts, people seemed to identify the part marked “510” often had cracks between the part (referred to online as a resistor, but I’ve no idea if it is actually a resistor) and the circuit board. On my circuit board, the culprit was the part marked “300” as you can see below.

I fired up my soldering iron on the 30 watt setting.  All I needed to do was touch the hot tip to the joint for a second or two to melt the joint back together. Don’t hold it too long or you’ll cook the part. You can see my fix below. It’s not pretty, but it did the job and the clock is now happily telling time.

Reassemble everything in reverse order and you will be good to go.

  1. Thank you! I was able to fix my 2001 CRV clock using you steps. I have the same clock with the same crack on the side of the “300” resistor. After several years without a dashboard clock now I’m a happy man.

  2. Mr fix it clock man– I was very happy to know that your instructions helped me a lot. We just has to solder one of the resistors and wolla the clock worked. Now the car is good to go for another 10 to 15 years.

  3. Great!! Mine too was fixed! It was the 510 labeled resistor underneath the display. Remove one side of the display to access the 510 resistor.

    It would be wise to resolder all these resistors.

    Thanks a lot!!

  4. Wow,what an easy fix,thanks Geoff for the fix,i couldn’t explained it better,took me 15 minutes and et voila.

  5. i tried it with touching solder gun. I just connected the clock to the wires before putting in vent I.had to press the r button and whamo it work. Now I put it in the vent put vent in dash it worked great. You the MAN !!!!!!!!!

  6. brilliant !! hairline crack across 300 ohm res on lh side – fixed with microscopic soldering – many many thanks

  7. Ur the bomb. 10ks man ur Iillustration did the job my CRV clock works now. From NIgeria

  8. Thank`s to this write up I am pleased to say my clock is back working after 3 months of staring at the blank space . I just soldered all 3 places as it was impossible to see a problem .

  9. Thanks a lot… my wife no longer wants a new car! I took the shotgun approach and resoldered everything I could get access to.

  10. Noooo bull this help us big time (crv owners)
    Me and my 3 other friend with crv had the same problem
    Now I’m there hero hahahahhaha. I fix my and there’s
    U the best bro…

  11. Another thanks, my clock is working again! I couldn’t see a crack but touched each joint with the soldering iron to be safe. My bezel was tight and when it popped off I lost two clips behind the dash. Manged to find one. Three was enough to hold it securely in place.

  12. Thanks for these instructions! Mine were both the 510 and the 300 on the left. I don’t know if cooking the resistor is so much a problem as knocking it clean off the board. They are all surface mounted and apparently the 300’s join under the display was so poor that when I softened one side, it went sliding!

  13. Great post, fixed my clock in 20mins, thank you very, very much for posting this info.

    All the Best from Brisbane.

  14. Worked perfectly. Dotted all the solder joints with my $12, 20 year old Radio Shack soldering iron and BINGO.

  15. Excellent instructions, my Honda CRV Clock is now working. Many thanks.

  16. Thanks! It fixed mine, same resister #300. I should have heeded your warning about just touching it, because the entire resister came off. I figured it was trash anyway, so I tried soldering both ends. I got it back on, and it looks awful, but it’s working. Who cares how it looks, right?

    It made my wife very happy. Thanks a lot!

  17. Very helpful! Thanks

  18. Well either I don’t know how to solder or my Weller 25w is not good enough for this.
    my clock on 2000 CRV the whol 510 one was off the board. I tried many times to solder it back on, but the solder won’t stick or the original solder is not melting. it seems to stay put and I even tested in the car and it works! but as soon as I click the board back into its case, that vibration sends the 510 chip back to rattling around inside there. Please help! do I need a new soldering iron?

    • Hi Doug, Not sure I can say what the problem is. There is the possibility of some basic soldering techniques at issue. You might need more solder, or you’re only getting a cold solder joint which doesn’t really stick. Googling solder techniques might help on that front. The resister actually should have little prongs that go down into the circuit board. It sounds like if it broke off completely, well, I don’t know what to tell you. I’d go with a little more solder first. Good luck.

      • Well, I finally got this fixed, It was my soldering iron. 25W just doesn’t do it. (Or maybe it is defective) as I borrowed my buddies 40W iron and it worked like a charm! no problems and the clock works wonderfully now!
        Thanks SO much!!!
        Thanks for the tips!

  19. hello there, it worked perfectly !
    thanks.

  20. Geoff, Thanks so much. Your solder instructions and the comment of lifting one side of the display in the comment s(my 510 resistor had a cold solder joint) convinced me to give it a try. Dealer wanted $288.50 for a new one.

  21. Thanks for the information. These resistors are part of the display circuit (inverter HV circuit) to drive the NIXIE Style clock display used before LED technology was easily available.I wonder why Honda used this type of display in their car in the 90’s as LEDs display was readily available during that period.!!!

  22. Great information! I was able to touch both 300’s and the 510 and get results. I did not have to remove the display or even touch the contact underneath the display.
