So as the weather has warmed up here I started having the problem described in this thread:

https://www.g8board.com/threads/inte...blower.220322/

Given my mechanic was off for the Holiday week I took a flyer and ordered the correct GM part number for the interior R9 relay (blower) and "wa la," I'm back in business!

This is the second relay issue I have had in 12+ years. The first one was the "key stuck in ignition problem," which my long-time mechanic replaced for free on a "drive by." This time it cost me $5 through Amazon.

Hope this helps someone in the future!

Happy 4th!
