Cascadia brake lights

[dzenis79]

Hello Everybody, I have 09 cascadia and i have a problem with my rear brake lights, only one of them works at a time, when i turn right turn signal on the left stop light is on, but when i turn the turn signal off the right stop light won't turn on, so left is on right is off, when i turn the left turn signal on, the right stop turns on, when signal off left is off right stop is on, when i turn my hazard lights on, after i turn it off i have no stop lights, i tested the lights with brake pedal pushed in, replaced the turn signal switch but it didn't help, did anybody have a problem like this? i checked the harness to the lights and it is good, i disconnected some wires from sam cab and the lights came on with ignition off and stop lights worked, if you have any ideas please let me know, thanks, i also checked all fuses and relays in sam cab
