Actually, that fuse feeds a lot of control circuitry.
 
Unfortunately I'm travelling tonight, and don't have access to my files till late tomorrow night.
 
In the mean time, there is one thing you might look at, is the wiring harness in the trunk. The wires can rub against the trunk frame as the trunk opens and closes....particularly if you've jammed things in the trunk. Look in the drivers side front of trunk. You may have to crawl in the trunk, and open and close the lid to see the movement of wires. This is really a shot in the dark without any diagnosing, but gives you something to look at.

In re-reading, should have said..... that fuse "also" feeds a lot of control circuitry

Okay, here's the scoop.
 
As mentioned, the 10A Gauge fuse handles the 'gauge' which is the combination meter....but it also feeds a lot of control circuitry in a number of other devices, so for example, there are devices which take two fuses to work. The 10 gauge fuse feeding the control circuitry, and then another fuse actually feeding the device.
 
But first let me give you everything that is downstream of the 10 gauge fuse in your model.
 
- The ABS (anti-lock braking system)
- Backup light
- Charging
- Combination Meter
- Cruise control
- Door lock
- Electronically controlled transmission and A/T indicator
- Engine control (the main engine computer)
- Headlight (w/daytime running light)
- Key reminder and seat belt warning
- Light auto turn off
- Moon Roof
- Power Window
- Stop Light
- Tail Light
 
Because this fuse controls so much, it is one of the harder problems to isolate the problem cause. I'd suggest an approach to isolate as follows:
- Stop using moon roof, power windows, cruise control, and door locks. If the fuse blows without using any of those, then lower probability that those are the source of your problem.
- Look closely and tail lights, stop lights, reverse light bulbs. Make sure all of the filaments look good and the correct filament is working on dual filament bulbs. You may even just go ahead and replace the bulbs since they're cheap, and your vehicle is 9 years old. Check for wire rubbing in the trunk, as mentioned previously.
- If you still haven't isolated the problem, get a volt/ohm meter, and meter out the brake switch, the neutral switch, and reverse switch. Work the switch on and off and look for erratic meter movement.
- Take your vehicle out to someplace safe, and put it into a panic stop to verify that the ABS system is working correctly.
- Still haven't found it, give up and take it to a dealer. The rest will be too hard to work on yourself.

I took the advice from your original email and checked the wiring in the trunk. I found 2 wires broken, and three others that had bare spots. I also replaced the fuse and tried the power windows (not them), and then shifted into reverse, which immediately blew the fuse. After repairing the wires, all is well! I appreciate your expertise...as you probably saved me several hundred dollars at the dealer.
 
Best regards, John

Thanks Kiawah. It finally got worm enough and quit raining long enough to check this further. Turns out power windows don't work anywhere, but door lock/unlock works on passenger side, so I figured pretty much eliminated power relay and fuses. Checked the wires to left door and found the white/black wire broken and blue half way broken. After figuring out how to get panel off of door, repaired the broken wires and taped everything up. Had a lot with cracked insulation. Regarding the door panel, slide a small blade above and below the inside door handle/lock lever to release the cup that is behind them. Then you can get the panel off.
Thanks again for your help. Wife was complaining now that the weather is getting warm, with no windows working.

click sound in my 99 camry by holly99

I heard a clock ticking sound from the fuse box two days ago. It was from the moroon color square 12V relay, which is labeled as "HEAD" on the lid of fuse box. I did not do anything with the sound during past two days and this morning I was not able to start my car--no sound at all. It happened three months ago in the winter that I had tough time to start the car---I had to keep turning the key for several times.
 
What is the problem? Is my battery died? or the battery was drawn by some kind of leakage?

I'd suggest starting with a basic electrical check of your battery and alternator, as well as verifying that the battery terminals are tight and free of corrosion.
 
Many auto parts chains (Pep Boys, AutoZone, etc) will do a complimentary check of your battery and alternator under load. You need to make sure you are starting with a good battery voltage of at least 13v.
 
Will the vehicle start with a 'jump', so you can drive it to get the battery/alt checked?

Thank you very much for your reply. I took the battery to Autozone and it could not be recharged. Got a new battery tonight and car ran right away.
