70 Coup DeVille.
Just got it a few days ago so have done no troubleshooting.
It has the autoclimate control with the rotory temp ****. The blower blows only in the low postion. The a/c compressor kicks on and it moves to the defrost position when selected so it appears the selector knows what position it is in.
How do I troubleshoot this? And/or how do I just hotwire it on hi? Our windows don't work so it gets quite hot inside.
