If it works in some switch positions but not others it's a fair bet the switch is the problem. Do check that the slider has not been turned over, that can cause some very odd problems.

I found you could check the switches with nothing more than a continuity tester, just make sure that the signal goes from a pin on the module to the switch, then out of the switch to the next switch and so on.
