1996 Jayco eagle series 10 Coleman TSR a/c only. the knob broke off the selector switch and also found that one of the spade connectors on the backside of the switch had broken off too. i got a part number off switch 6759-325 but search only found a replacement of 6759-3251. will this switch work? any good suppliers? i also need a knob for the thermostat. thanks.
