I have been steadily pecking away at the 71 - usually at the end of the day. Today I received the new blower fan from the rear of a 1985-2001 Astro rear console. It is identical to the existing fan except for the size of the motor.

I mounted it in position and tested it out - moved quite a bit of air compared to the OEM one run next. One thing I also noticed was a hell of a lot of air was blowing past the blower shroud to firewall interface. This was sealed with 3M ribbon caulk. A quick inspection with a flashlight reveled a sizable gap on the upper left corner. More ribbon caulk sealed that from the inside as the firewall was somewhat warped in that area.

One wonders how many GM's had this issue right out of the factory?
