Im looking for pics from a service manual for the heater box which shows the vent doors cables heater core fan assembly. The car blows warm air when switch is turned to HOT, I have A/C. GM Service center suggested that i pull the fuse for the A/C as to not get cold air introduced into the system during the winter months (stupid). Good air flow,heater core not leaking, trying to get hot air to warm interior of car and defrost windows. Any help would be appreciated.
