Not sure if you can remove the light housing without removing the panel but you if you can disconnect the plug and check the voltage. Or check the voltage at the bent prongs. see if there is any. check the resistance to see if there is a short. (without bulb plugged in or power going to it)

Well i got a multi meter and took the door panel off now i just need to figure out how to test the door ecu and the door lock sensor or whatever.
I just find it strange that all other door functions like windows and locks still work, isnt that what the door ecu does?

check the voltage at the plug that plugs into the light that is not working
If you have voltage at the plug then (with the plug still disconnected) check the resistance from the terminal to terminal on the light socket (the thing the plug plugs into that is on the door panel) Check it without the light bulb. Your resistance should be infinite ( a 1 blinking on most meters)
If you dont have voltage at the plug then check voltage at the fuse also check resistance across the fuse with fuse removed just to make sure it is good (this should be zero or near zero resistance)

I got frustrated and took it to Toyota. I absolutely suck at electrical....Hopefully its something simple that i over looked.. i just need them to tell what part/s are bad so i can order them from sewell.
Anyways thanks for your input, I really appreciate it. Ill keep this thread updated with the conclusion.

So i turned out to be the door ECU. I guess a circuit inside is fried, the master tech jumped the input to the output ecternally and it works.
Trying to decide weather or not to replace it. 260 from Carson or 100 on ebay...
