Where is the Heater Control Valve on a 1994 Chevy Camaro with a 3.4 V6 engine with air conditioning.

Try cleaning the throttle body and the idle speed control valve, they get full of sludge and this causes stalling. Use a product called CRC Throttle valve cleaner on both parts, DO NOT USE CARB CLEANER IT WILL RUIN THE PARTS.

you have air in the system ,if you have not done a radiator clean ,the put radiator flush in the radiator then go for a short run.about 5 miles then go back and drain the radiator.now remove both radiator hoses.fill with water it will pour out as you do so..if clear refit you hoses.fill will a 50/50 mix of antifreeze. now put your heating on full open your window .with your expansion bottle cap off ,run your engine on tick over till the water starts to head up.then refit the cap.this is done to bleed the air out both in your heater core .and the radiator.

Are you check right "firing order" ? Some "check engine" light on dashborad turn on?

replace the blower

thermostat, heater control valve, or stopped up heater core

you prob need a coolant temp sensor
