Hello fellas, I'm working on my old school and need a little help with my vacuum hoses that come off the Ac _heater control. Nothing is hooked up so some pictures would be very helpful..thanks

 

Welcome to the zoo.
You need to buy a ‘70 Oldsmobile Shop Manual, available on EBay, this manual has almost all the info on your car, including ac/HVAC diagrams, etc..

 

Thanks will do

 

I have a 69 and the controls are all vacuum operated, ie it the same on a 70? I know it switched but not sure what year. The Chassis Service Manual is the one to get.

Great thank you so much..working on that.

 

Here's this to get you going while you pursue a copy of the assembly manual.

 

Hey fellas. My assembly manual finally came..Cool!.. So much stuff I needed to know. However after looking at my heater/ ac control under the dash I noticed that I have no vacuum lines at all ? Anyone know where I might be able to purchase these.

 

My situation was similar, I had lines but no vacuum canister, no ductwork, and all lines were disconnected. OPGI shows a vacuum hose kit, all color coded, but I cant tell if it is for heater/AC controls or not. You should give them a call at 800-243-8355

Ames Pontiac (believe it or not) is a good source for the vacuum lines. They sell them by the foot and they are color coded just like the factory ones.
