The arm on the combo switch fell out of it's socket and I see two small holes at the levers end.Anyone ever fix this?Seems like it needs a pin of some sort to hold it in.Still functional washer button and wipers.Any fix besides a whole new unit.Como switch number 84310-35180.

 

Just swap it out with another if it broke.

:wabbit2:

 

Seems it needs a pin like the kind that holds a watchband to the casing.Anyone have/or know where to get that little part if available?The lever has wires going into it so I'd have to splice the wires if I changed out the whole lever?

 

Your local dealer should have a part diagram of the entire thing. Or...go to toyotapartseast, enter your vin and look up the part yourself.

Pretty easy...
