OEM A/C question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

this is my first post. I've been browsing the forum for about a year now. Thanks for all the great info.

the question today: does anyone have or know where to get, a diagram, manual or link that will show me the routing of the vacuum lines for my heater & A/C ??

It's a 69 C15 with all the OEM parts there. but nothing works. fuses are OK. the fan comes on by itself sometimes but I get no heat or cold.
I can hear vacuum leaks and several hose are broken or hanging loose. I'd like to replace all the hoses but it's not clear where they all go, or where they came from.
also, there is a vacuum acuated valve in one of the heater hoses, but there is no vacuum line in the engine compartment to hook it to. ideas?

I know I'm asking for a bunch of info so,
Thanks in advance for any reply.
