ISO Manual that shows detailed AC for factory AC

[scottgull]

I'm looking for a manual that shows detailed information on the factory AC system. I'm sure there was a factory service manual in the day that had all of this but I'm not sure which one to order. Any leads would be greatly appreciated. I have the generic Hanes manual but I am looking fort more specific details. Vacuum line routing and so forth.

Thx

My bad 1981. You made some great suggestions on a earlier post that i did not lack of blower volume but unfortunately, I still havent found the problem for that. The whole system is coming out in the next couple week and thats why I am looking for a detailed manual.

I fixed things as I tested them when I rebuilt my A/C system.
I also have a Haynes manual but it isn’t much help for A/C repair.

Pull the heater box from under the dash and we will go from there.

I think the system in my 80 is identical to your 81.

is it possible to run a straight jumper wire to the blower motor on these? resistor keeps popping in my limited mind. i ordered a '72 assembly manual few weeks ago, called them monday, pretty much was told when they know I'll know.

found this, 78 though. https://nastyz28.com/threads/heater-blower-wire.197484/

Yes, you can run a jumper wire to the blower motor for testing.

It’s a big power draw so I wouldn’t leave it without a fuse for long.

yeah, It's just a ramblin' thought. The old stuff gives me enough grief.

Ill let you know when I get it out.

The 81 GM F Body Service manual has a complete detailed section on the factory AC.
