Replaced the felt in the sliding rear side window on the right side... for the life of me I can't figure out why it doesn't want to seat in the very hole it came out of! Also, based on elbee's suggestion, I measured and learned there is room in the centre plate for the heated seat switches. The bad news is there wasn't room to snake in the plugs to the switches, so either I need to figure out how to un-pin and re-pin the connectors, or take apart the dash far enough to snake them in from the side.
Looking for a switched connection, I thought maybe I could tap in to the cigar lighter or rear window wiper switch. The front de-icer and radio are plugged in there now, so that's probably overloaded. On a hunch, I checked voltage at the lighter with the ignition on but engine off, and saw only 11.8 volts. This makes me wonder how much resistance is in that switch! Should probably think about replacing that, too...
