So first of all my every time I press the unlock Button on my remote it unlocks the car but when I try to lock it it doesn’t do anything I have no power to my windows my trunk every time I tried turning on the car it won’t crank up it says when starting the engine depressi the brake pedal.. I read a lot of Forums were people saying it was a brake light switch OK I switched it I bought a new one at AutoZone, can it be the relay? Any fuse? What fuse can I look for? What relay can I look for? Can my module be out? .. my battery is less than a year old, so is my alternator. I need help pls.

 

Could be a fuse, start looking for a busted fuse. Good luck.

 

Like mentioned above check your fuses.

I'd probably read here.

There are panels on both driver and passenger side. Two more in the engine bay. If you have the manual find the sections for visual aid.
