Default 1990 300SEL climate control help

My climate control just completely stopped working. And it seems to be blowing hot air. I check the fuses, but it must be a relay. Does anyone have any ideas for me. Thanks in advance.

I am not an expert, just talking from experience.
Your A/C Puchbutton Control Unit could be at fault. This is very common for MBZ with the age of your car. This is very simple to replace.
