Weird - AC Heater related to windshield wiper

I just got my car back from dealer. My car had AC heater problem. Under the AC Heater item in the invoice, they replaced heater motor which is normal and at the same time, they need to replace the windshield wiper motor assembly. Why are they related (AC system and wiper)??

Also during this visit, I asked them to check the oil leak for me even I don't see any evident for oil leak. They found the tranmission fluid leak from electrical connector and they fixed the issue. I think if you bring your car to the service next time, it is worth to ask them to check the oil leak. They may find something interesting.

There is heated lines/hoses and housings for the wipers for the fluid. I know on the 2003 and 2004 the whole lines are heated on the 2005 just the line ends are heated.

Lines are heater electrically not with the vehicle heater to the best of my knowledge. Must be that in the course of repairing the heater they either damaged someting or saw a problem and corrected it. Why not ask the dealer??
