CADILLAC ESCALADE AIR CONDITIONER BLOWS HOT

Cadillac Escalade Ac Blower Wires Very Hot. Blower Turns On And Off At Random. Recently The High Setting Stopped Working. Need A New Blower?

I Set My Temp At 70 And The Heat And Air Keep Getting Hotter And Colder. It Acts Like There Is No Temp Control. We Have To Shut It Off It...
