brake lights

[timsalive]

I have a 2004 sienna le that I have had so many problems with and have been told in no uncertain terms no luck from the dealer. One right now is that the brake lights are out. It happened before and I replaced the low profile 10a fuse. Now it happened again and the fuse was bad and replaced it but no luck. I wonder if it could be the pedal switch? Side note. I do have a towing harness but have had it for 4 years no problems. I only tow once a year. Also a fun one is the transmission wont shift unless you push the safety switch at the handle. Now it gets weird in that I turn on the running lights and the transmission will shift out of park like normal. Toyota says this is impossible. I tell them it is possible because it is what is happening. By the way power door cable broke, a/c went out 3 times and dealer wrecked van at dealership and tried to deny it. They finally fixed the dent and paint. Can I tell you how sour I feel? I have owned Toyotas since 1982.
Any ideas on the brake lights. Bulbs are good, I beleive they are on the side mount correct?

Thanks for any info

If it wont come out of park unless you push the manual button, and then IT DOES come out when you have the headlights on then it could be the trailer wiring backfeeding thru the brake lights.
The trailer wiring could also be not allowing the brake lights to work since that signal runs thru it.
I would disconnect the trailer wiring and retunr the vehicle to stock and then see what happens.
Make sure the fuse is good.
Brake switches do go bad and can be the cause of the brake lights not working, but turning the headlights on points to the trailer wiring for me.
Just an idea
