I cant find where my brake light fuses are for my 03 chevy silverado. the left brake light is out and the bulb is fine, but I dont know where the brake light fuse is.

If after checking the bulbs are ok then the fuses could be suspect!

Change the bulb.The bulb has two lights.Running,and brake light turn signal.Its the bulb

I had an issue like this one on a 2007 Colorado. I assume you mean the turn signal indicator inside the truck lights up. It was a bad bulb. think it was the turn signal bulb on the side that is lighting up. As for the gear indication being dim there is more than one bulb that lights them up and one may have blown. I hope this helps.

well it sounds like you have a short fro junction block to taillights , make your own wire from where you know you have power to brake lights . and that will tell you where to go.

I've worked on these the first drove me crazy. its the turn signal switch every thing runs thru these. head lights, turn signal, brakes. except the third brake light. it runs directly from the brake switch. go figuare

Some of these had two fuses for brake lights. One for the top/center stop lamp and another for the rear left and right brake lights. Usually one said "stop" and the other said "brake" and one was in the underhood panel while the other was in the dash fuse panel. It's not uncommon to blow a brake light fuse [LR and RR] if you tow a trailer but some of these had seperate fuses for the trailer lights also. If you have a test light check both sides of the two fuses for power [ignition key on] while stepping on the brakes. It should at lest narrow your search a bit.

check all your wiring from the light to the fuse panal. that should fix it

I just had the same problem on my '04 Silverado. All it was was corrosion in the socket/bulb. Put some dialectic grease on both the bulbs and worked them in and out a couple of times and now they work fine. Was weird that they both went out suddenly and together but I guess they are made exactly the same.

ljones, Did you check the "VEH stop" fuse in the left side instrument panel fuse box. There are 3 stop light fuses, 1 for all the stop lights located in the under hood fuse box. 2 in the left side IP fuse box. 1 for the upper stop light and 1 for the lower stop lights. The fuse box in the IP is where the upper and lower stop lights split. Let me know.

There is a probable bad wiring connection in problem one and three.
#2 Possible water leak causing bulb break. Try wd40 in socket. you need a wiring diagam and cheap voltmeter if you want do it yourself.
