99 Honda CRV Clock Fix
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.
