74LS86 Circuit issues

[DebeliMajmun]

Output is always high input is 5v on the dedicated rails on the breadboard.Can you help me find the issue?

Post a schematic, or at the very least a high-res clear picture.

For starters, the supply wires going to the DIP switch are off by 1 position. You've connected the gate inputs to switch 1 and 2 but the supply goes to switch 2 and 3.

Additionally, you should add pull-down resistors to the gate inputs. You should never leave a input floating as it would do now when a switch is turned off.
