What exactly are you asking? If it's hard to replace the bulbs? What is your ability? You can reach the signal bulbs (with a bit of contortionism) without pulling the instrument panel. Quarter turn and they come out, pop new bulbs in the holder, reinstall. Or do you have to diagnose a non-functioning signal? That requires more extensive disassembly... Are the signals the only thing not working? If more, you need to dive deeper.
