Default Need Help with fuses

I have a 1999 Camry. Dome lite doesn't work. Replaced the bulb.
Initially it did work but then it stop working within a couple of
seconds. I suspect the fuse is blown. My wife also said that the power
locks stopped working.
The challenge is, although I have found the fuse box location under the
dash on the left of the steering wheel, I don't know which fuse is
which. Coincidentally, the cover for the fuse box is missing. I suspect
that their is a map on the missing door that explains which fuse does
what. If someone could tell me what size the fuse is that would give me
a start. Also, is there an easy way to remove fuses. I have a needle
nose pliers that I could try but maybe there is another tool that would
be more appropriate.

Thanks

Bruce

This fault is a good opportunity to either buy yourself a cheap $10
multimeter, which will indicate the prescence of volts (DC 12V) or a simple
test light. The latter is made by connecting (soldering preferabley) two
wires to a festoon bulb (like the one in the dome-light), one on each end.
You then put a alligator clip on one wire, which you clip onto the car's
chassis or earth, and some sort of probe on the other wire to touch on
electrical contacts. If good volts are present, the bulb will light.

Sometimes the clips the replacement bulb fits into get spread slightly,..so
note that the new bulb is secure. Your test device will also quickly tell
you which fuse is blown.

I am not sure how this helps me locate the fuse that is blown.

If a fuse has voltage on one side but not the other it is blown. The ATM
style fuse used on most autos now as well as the ATC style, both have the
two tabs sticking out of the square plastic head, have a small metal point
you can touch with a tester to check. You don't even have to take the fuse
out.
If you want to do your own work and don't know how to do simple tasks, you
definately need a repair manual.

What I am really looking for is someone who has this vehicle or has
access to a diagram of the fuse layout.

The owner's manual should list all the fuse locations and functions.
On my '94, the dome light fuse is under the hood in the fuse holder
near the air filter. That fuse also controls the lighted ring around
the ignition switch and the radio and I think also the trunk light. So
if the illumination around the ignition key works, it is probably not
that fuse.
Also, when you remove the cover, there should be a small plastic tool
for removing fuses.
If you're blowing fuses, you will need to determine the cause of
course, or the new fuse will also fail.
Sometimes the wiring near the door hinges goes bad with flexing over
time, which might explain the power lock problem.
In my experience, the most common problem with the dome light is the
pin switches in the door jambs. Check those also.

If you just check you'll find the fuse that may be bad. The fuses that
are only on with ignition won't have power on either side, while the
fuses that are hot constantly, like the dome light circuit, will have
power all the time.
There should only be less than 20 fuses, which could be checked in less
time than it takes to write an email asking for the exact location of
the fuse.
