I pulled the push button part of the climate control in both cars and forgot that the default is to full heat. My spouse drives the car (84 & 85SD) and reminded me that it is getting warm and that she'd prefer to have the heat off.

Is there an easy fix that won't take time away from the other projects? I suppose that I could look up the routing and plug or reroute the hose to the heater core. Is there anything easier?
