More information: I put a spare gear into the pull down (from the old one) and it did extend when I reinstalled it. However, it won't go down. I removed the trunk lid switch and ran continuity tests on it. It has a black wire in the middle (gnd), an orange wire and a red wire (both power?). When it's "open, " i.E, when the trunk is open and the light is on, there is continuity between the orange wire and the black wire. There is no continuity between the red wire and the black wire at this time. When the switch is held "closed, " i.E. As if the trunk were closed, there is continuity between the black wire and the red wire, and none between the orange and the black.
Next I ran voltage tests on the connection side to the trunk lid switch. There are 12.54 volts at the orange wire when grounded to the black wire. There are no volts at the red wire when grounded to the black wire. There is continuity from the connection side to the connector at the pull down. Orange to orange, black to black, red to red. However, with the volt meter on the red and black at the pull down motor, I "close" the trunk lid switch and no voltage shows on the meter. It should, I believe, but it doesn't.
So, the switch appears to be trying to reroute power to the red wire, but no power flows. I checked all the fuses in the trunk and they're all good.
