I know that GM designed it that way. But sometimes we run the roof A/C while on the road. I was told how to do it once. We all know how that works out. Bob Dunahugh 78 Royale

Bob
There is a resistor pack located on the driver’s side of the heater box. Clip the yellow wire and it disables the low blower setting from being on all the time.
Did mine years ago.
