Can any of you guys have a pic of your heater control valve on any v8 between 72 to 84 gm vehicle??? car or truck i can't locate the correct valve for my 84 t/a at any autoparts store. i need one for the 3/4 side. thanks

I know this doesn't help you specifically but why not delete it?

i deleted the valve in '94 tired of hot air blowing on me while driving in the heat and it defeats the purpose of having ac. just don't want a mullet mod anymore.

I have one sitting around. Later than what you're looking for since it came from one of my cars, but I forget which one - likely the V6. Operates with vacuum applied to it. They all look the same to me...

Some of them only had two lines IIRC.

This is for 87 on up gm with bypass

This is the one but only has 5/8 nipples

This one has 3/4 nipples if you have this style on any of your GM i like to see a pic of it in your car/truck.

Mine is like the first pic. Never seen the third style before.

They make hoses that are 5/8" on one end and 3/4" on the other.

I've never had problems blowing hot air on cold with the valve delete. Sure your flapper is working good?
