AC & DEFROSTER ON AT THE SAME

1996 Mercedes Benz 420sl

Air Conditioning problem
1996 Mercedes Benz 420sl V8 Two Wheel Drive Automatic 104000 miles

Sometimes when I have the AC on, the defroster comes on at the windshield, so it is blowing hot air while the AC is blowing cold air. I keep the AC on automatic at 72 degrees. Also, for the last two days, the two vents on either side of the dashboard have a really small amount of air coming out. I have had this car for about six months and like it a lot, but I keep learning new things about it. Do you know if the two things I have mentioned are normal for a Mercedes, or is something wrong?

Thank you,
