Changed the driver side HVAC blend door motor on the Bonneville. Not a bad job to do if you remove the driver'* seat ... allows you to lay on your back with your head under the IP to see what is going on. Two screws (5.5 mm) and a little prying to get the old one off, check the blend door for free movement, line up the flats on the new one with the flats on the blend door pivot rod, two screws to button it up. Took me about an hour, including pulling and re-installing the seat.

This post moved from lounge to 2000-2005 Bonneville section. To good of information to get lost in the lounge.
