Customer Question

Tail lights and brake lights went out in my 2002 Tundra. I checked the 15 amp fuses under the dash and they appear to be fine.

As in the 15 amp stop fuse and the 15 amp tail fuse?

Customer: replied 1 year ago.
Correct.
Expert:  scionking replied 1 year ago.

Are you able to test on these fuses with a test light of voltage meter to see if they have power at them.

Customer: replied 1 year ago.
I don't have the tools.
Expert:  scionking replied 1 year ago.

OK....are the license plate lamps working?

Also is the high mount third brake light working?

Customer: replied 1 year ago.
Those are also not working, but the reverse and turn signals work.
Expert:  scionking replied 1 year ago.

Do you have a trailer hook up on the back of this?

Is there any corrosion on or around it.

Customer: replied 1 year ago.
No trailer wiring. It does have a topper which I recently removed to carry large items and then put back on. The third brake wiring connection on that appears to be fine.
Expert:  scionking replied 1 year ago.

And you are sure those were the fuses you checked? Some times its hard to read the diagram on the cover compared to the fuse box, Ive found it useful to pull the fuse on either side of it to just to be sure.

Customer: replied 1 year ago.
to double check I just switched the "ACC" 15 amp fuse with the "Tail" fuse. No change.
Expert:  scionking replied 1 year ago.

Would you be able to get a test light? Progressing any further will prove difficult without.

Customer: replied 1 year ago.
OK. Will check back later.
Expert:  scionking replied 1 year ago.

Any luck with sourcing a test light of volt meter?

Expert:  scionking replied 1 year ago.

Do you still require assistance with this issue?

Customer: replied 1 year ago.
It is not fixed, I tried to buy the light but they sold me a fuse checker, totally useless since you can see if a fuse is bad. Can't do anything more until next week.
Customer: replied 1 year ago.
Just got a test light, can we continue?
Expert:  scionking replied 1 year ago.

Yes we can continue, I have limited time right now but will be on later.

Customer: replied 1 year ago.
First thing I need is a good place to ground the light in the cab. I have no problem under the hood checking circuits but I cannot get it to light up in the fuse panel under the dash, even with circuits that I know are good.
Expert:  scionking replied 1 year ago.

Try clipping in the door jam, on striker nuts.

Or under dash on the brake pedal bracket.

Customer: replied 1 year ago.
OK, actually did all of those, could not get a light from any fuse socket. Had the key to aux, radio on, pulled the fuse, radio went dead but I could not get the test light to light up. I don't know what I'm doing wrong.
Expert:  scionking replied 1 year ago.

So your test light works on the under the hood but not inside the vehicle? Your leaving the fuse in to test right and making contact with metal terminal on the out side of fuse? and this is the same for all fuses?

Customer: replied 1 year ago.
it turns out this cheap light doesn't hold the bulb in place when it is upside down. Anyway, finally got a check on the 15 amp brake and tail fuses and yes, they light up, (fuse in place probe at metal contact.)
Expert:  scionking replied 1 year ago.

OK so we know you have power to the fuses, next I would check right at any of the bulbs to see if you have power there to, we may be dealing with a bad ground issue.
