The A/C in my '88 Supra cools like a champ. In fact, it cools even when it's 45 degrees outside and the control set to max heat. Anyone experienced this problem? Help!

Your heater control valve is probably stuck. Look on the TSRM but it is located on the rear passenger side of the engine bay on the firewall.
