My 04 gmc canyon tails lights and 3 brake up top are not working correctly.the left side has all lights stay on and the blinker is very dim when i tap my brakes the left turn signal turns on. on the right side i have no running lights or brake lights but the blinker works just fine and no lights on for the 3 brake light up top. ive replaced bulbs and fuses but the fuse for the stop keeps blowing. would the brake lamp switch be causing this problem?
No , if your blowing a fuse it is the result of a short to ground on the electrical circuit , wiring ! Do you know how to do automotive electrical trouble shooting ? Using a volt meter ? Do you know what a wiring diagrams is ? How to read one.

Finding The Source Of Electrical Shorts In Your Car
SOURCE: 2005 Canyon turn signal problem
No, but that's probably where your problem is. The wires get the hell beat out of them by stones, and then they short out and cause problems. I would take a look at it.

its your blinker box.. all major lights run through there

I have notice that this is a common problem. The socket most of the time goes bad, I don't know why but they just do. You can pick them up at any parts store for around 5.00 each. If you don't have a volt meter and ground straps to test it right, then I would try changing the sockets out. Quick and easy. Let us know how it goes.

you probably got the wrong bulb
those are usualy a different number higher wattage, they look exactly like an 1127 but are a 2027 or even a 3027 check the bulb base it has the number printed on it
