Air Conditioning problem
1991 Mercedes Benz 300e 6 cyl Two Wheel Drive Automatic 179000 miles

WHen I start my car and my control is set for A/C
I get cold air then all of a suddon it changes to hot air and my temperature wheel is still set in the blue asking for cold air. At the moment I grounded my heator valve and am getting only cold air only.
Can any one tell me what is my next step for solving my problem
