Thank you for that link. Taking a look in the manual on how to check the voltage at the switch. Guessing it probably needs to be cleaned?

Possibly. It could be bad, as @HemiSSDart mentioned. It's a common failure. I always like diagnosis though, which is why I suggested the wiring diagram. That way, there's no guesswork and no wasted expenditure.
