blowing heat in the summer?
 

Hey Guy's,

I have a problem. My 1987 300E has had the climate control box on the dash go bad and the system is stuck in the mode of blowing hot defroster air up from the top of the dash. I am unable to fix the control panel as of now and wondered if there is a quick fix for the system to stop the hot air from blowing. In the old days, we would just valve the heater hose off under the hood....does this fix apply here and which hose is the one. Thanks.

Regards,

Bob
