I have a new to me 2005 Yukon SLT 4X4. When I start the vehicle, the A/c blower will not turn on until you turn the fan to the lowest setting and turn it back up. Have the dual climate control system. I Have a few other issues that i will be addressing, that I have already found answers to on the forum, but havent seen this issue addressed in any old threads. Any ideas?
a/c fan wont turn on until turning fan all the way down after first startup
