Checked under hood, no blown fuses, tested all switches - all seems to work well. blower works and a faint burnt smell is still there. My wife said smoke did come from the vents, but all seems to work well now. I guess need to find time to pull the blower, or take to a mechanic.

Just went back under the dashboard to see if I could get to the blower. Easy access to the blower-the cover is next to the cabin air filter. removed the cover all looks well just a lingering faint burnt smell. Looks easy to pull but will have to wait until next week.
