Both brake lights are not working but DRLs are. Fuses and bulbs are good. Also, where's a good place to get a wiring diadram? Thanks.
You can get a wiring diagram here

Get a test light or meter and check for power at the orange wire on the brake light switch, then power at the other wire when brakes are applied, if nothing the switch is bad. If it is ok, then check for power in and out of the STOP fuse and the CHMSL fuse in lower left interior fuse panel.If ok, then the Turn signal/flasher module may be bad
