86 560 sl AC and cruise control prob
 

I have a 86 560SL and have a few probs to troubleshoot. 1. AC only blows cold air at the full cold temp setting. Any other setting on the temp wheel and the temp goes full hot!! 2. Cruise does not work... is there a fuse to check? I looked in the panel and there is not a fuse marked Cruise,,,is it somewhere else?

Any advice will be greatly appreciated!!
Thanks
