Yeah, what he said. I just lubed the bushings on mine. A moderate pain but not really difficult. It's accessable from under the hood. You get to remove all the waether stripping, the wiper motor, the plastic grills and a plastic cover that clips over the motor/blower itself. Beware of twenty year old plastic, it's brittle. A few drips of motor oil on the bushings & mine no longer squeaks and the current draw is way down. It needed it. I've read that it's a good idea to check the brushes when you're in that far, but I didn't. Getting dark, back hurt, needed a beer, etc.
The motor alone goes for about $100 and the assembly, $234 on eBay. Slightly higher at the dealer.
Reassembly was, as they say, in reverse order.
Great fun,
