Could be the combination control module in right rear of engine compartment

Can confirm. The Combination Control Module, which is in the right rear of the engine compartment, (seen from the driver's seat) controls that, and many other functions. I've seen the actual circuit diagrams, so I know this information is correct.
It controls wipers, power windows, convertible top retract and turn signals, and possibly more functions.
It's the module nearest the battery, inside the compartment with a lid, held on by screws, located next to the battery.
Mine blew out during a battery change, of all things.

Yes, that does happen, the component cant handle the voltage surge that sometimes accompanies this kind of service.
