I found the problem with my 99 clock!

[jdmidwest]

I saw the other thread on here on how to fix the clock on my 4runner. So I popped the bezel off and went to work. It did not take long to figure out why mine did not work, it is not plugged in! Further inspection revealed the problem, no wire to plug it in either!

Mine was Canada Made and imported into the US thru New York State. My vin number did not let me register on Toyota US website. A carfax revealed its travels from Canada into customs at New York State then down to Missouri to its first titled owner. I guess in Canada, you don't need to know what time it is.

Why would you install a clock and not wire it up? Anyone have a solution for this one? Anyone know the pinouts on the plug so I can wire some power to it?

just does not seem feasible that it came with a clock but no plug for it. Are you sure the plug is not perhaps stuck in the back of the radio bezel -perhaps in the "dead" port? The black port not the white one?

Got a picture of your wiring behind the top of the bezel?

Does that make any sense to you Canadian SR5 owners? It would have to be prewired would it not?

I did not dig futher down and look behind the radio, which has been replaced with an aftermarket. I just figured the wiring connector would be a part of the upper harness with the ECT, Hazard, RH seat belt, back window. I can pop it off and look behind the radio.

Looking at the other thread, it appears that the wire should be a part of that harness I mentioned.

Wow, that's strange. I bet the connector was there at some point. There should be 4 connectors at that top harness.

Maybe it's plugged into the dead spot on the inside of the bezel.

I would be willing to bet it is plugged into the famed "dead spot" I cant see any reason Toyota would spend the extra time and money to build and install a harness without a clock plug. I would unplug all of the connectors related to the ECT and rear window panel and I bet you find a plug that is in a slot with no pins to connect to, try plugging that into the clock.

Maybe when the aftermarket radio was installed, the person removed the clock plug or plugged it back into the wrong place. As for Canadian made, the 4Runners in Canada are also made in Japan so there's no difference in terms of where they are made.

show us a pic we will spot it for you if it is there...

it's a mystery..

let's play a game of spot the clock plug...glad you guys agree that must be what that dead port is for...let me try for a picture

okay look carefully-the clock is a vertical type plug-you spin it sideways all Tetris style and voila!

lookie where it fits to the right of the G- center of the picture and center of the bezel.

That is my Limited look woodgrain bezel but the black one is identical on the back as well.

By the way one of the Toyota specialty bulbs is between the G and the dead port-lights up to show you where the functions like the defroster are located- even when not switched on.

Between the vents at Top center:

hazard switch/below that is clock then the dead port, white port is the defroster I think and not sure about that orange one but the plug is orange to match it I am pretty sure.

dang it sure is easy to post photos now --this is great not having to use ^&%^%$&**^ photobucket any longer...

Ron you are awesome. I have this same problem, jdmidwest!! I went in to swap out my antenna and realized well no wonder it doesnt work - and also couldnt find the harness.

Thanks for the pic and explanation, Ron!

I fiddled with it this afternoon in the 108 heat index after I got home and found it plugged into the dead spot, I think. I plugged it in and still no clock. I checked the plug for power and found power in the right places. I took the clock out of the bezel and found the pinouts for battery - and +, acc, and illum. I took the clock apart and tried the pin solder fix, solder would not stick to the pins and the heat was too much over a soldering iron, in my shed, in the 108 heat index, so I put it back together and retired to the beer. I think I will try a big pothole in the morning to see if everything falls into place...

HERE'S ANOTHER THING TO CHECK!

I thought I had fixed mine using the soldering technique...but alas I did not fix it. My connections were good, but that wasn't the problem. The problem ended up being one of the resistors (I think) on the board. It's soldered connection on one end had cracked, and was only making momentary contact with the board. I discovered this while having just the board connected to the harness (no black housing attached), and my finger touched the diode and the clock fired up! Took me a while to see the crack, but there it was!

The resistor (I think that's what it is...not sure), is a rectangular component on the BACK of the board (opposite the clock face). You'll see at least 3 of them, and they are labeled with a "270", and that's all. The one that was cracked on mine was the bottom one, running horizontally. The other two are vertically oriented. I just re-soldered that guy, and it works great!

Good luck!

EDIT: It's probably a resistor, not a diode. See this write-up for a Subaru for a similar problem: http://jasonrowe.com/2007/02/17/subaru-wrx-2002-digital-clock-fix/

The component looks the same, but on our clocks it's on the back side of the board, and says 270, not 510. Same little crack, though!
