Re: Re-wire project!
With some searching I found your post you commented early Oman. I do beleive this is it. Now my question is, i guess i should have thought about this earlier in my decsion to completely remove my dash, but am i still going to be able to operate the car with NO Air condition, still utilizing the AC heater control. IF that makes sense. I had a local restoration shop hook me up with what they said was to be heater controls for a NON ac car. Looks different then mine, and from what i have done research wise, the non air conditioned cars had more cables that operated the doors to move air. But from your post in an earlier thread, I still have all the vacuum h oses connected to the back of the heater control. I am really hoping i dont have to do a bigger job to eliminate the AC components. Thanks again for your help.
"Vac does operate some of the doors in the in the air handler under the dash. This occurs in combination with the single cable that operates a large deflector door in the air handler. That single cable moves one of the big doors in the air handler but depending on other vac actuated "signals" to "pots" on the air handler different things will happen. As to heat ....remember you have hot water in the heater core at ALL times without the in heater hose shut off valve. Defrost and heat to the windshield area is controlled / managed by the air handler thru electrical and vac switches.
Everything done in that heater box is a combination of the position of the cable, the electrical switches and the "vac switches". When you move any controls (except the fan control) you are both activating electrical switches and changing the positioning of the vac manifolds / switches sending vac to different parts of the air handler.
Without the fan in an "on" position none of the other electrical switches in the control panel are "live". The fan not working properly is key here because the activation of the fan switch is the first thing that happens when turning on the A/C or the heat. You need an electrical schematic to trace all this interdependent electrical and vac activity. The manual has very good diagrams of the electricals and vac hook ups.
Explaining this in detail would take forever here. Look at a shop manual it will give you more info than you can likely stand about the A/C system."
