Alright, I will soon get my heater core replaced. In the future, I don't want this core to last only a few years and put me back to square one again and spend a crap load of labor to pull out another bad core.

I have bought a vacuum operated heater core contol valve. The valve is in the normally closed position.

Now is the part where I desparately need your help. I am looking for a electrically operated vacuum switch so when i turn the switch on, it will let the vacuum go to the heater control valve to open it when I need heat. I cannot find this simple type of switch on the internet anywhere. I remember there was a electical operated vacuum switch that was on my 85 toyota truck to temporary raise the rpm on my 22re when the a/c is engaged. cannot find that switch either.

Thanks for the assist.

Once I find this electrically operated vacuum switch, I will take pics and document this project for you guys to use.

This project will be used to prolong the life of my heater core. Also, during the summer when heat is not required, it should GREATLY improve your A/C cooling as the blend door won't get heated up from the heater core and pass that hot temps to the A/C side.
