I just purchased an 84 Cherokee Pioneer and have been going through it fixing it's quirks. The heater control panel was completely removed due to it not working for prior owner.
I popped it open and fixed the fried selector and now have a functioning blower motor, although it is defaulted to defrost.
The Chiltons manual as well as autozones online manual show only the engine vac diagrams.
Does anyone have or know of a vac diagram for the heating/cooling system that would include the heater control panel?

Tomorrow will be a day of chasing vac lines down, but it would be nice to know the starting point where the system gets it vac from initially.

I Appreciate the help. This looks like an awesome forum. Thanks for having it!

 

Maybe this will help others in need:

 

thanks for hte resource. Does this mean you were able to fix it? If not, we have a few who know the subtleties of this era jeep well. Hang tight.

Looks like it.
Hooked the black back to the vac canister and voila, all works well. PO had hooked the main Black tube supply line to the Blue Transfer case vent line. lol Guess he saw the open valve/filter and thought something needed to go there.

All the tweaks are done for now on this rig. Back to the 93GC on Friday for valve work and getting back together and on the road again.

Thanks again, and hope this helps someone else down the trails....

 

can u get me a bigger pic of that diagram? Old eyes aint what they used to be.

Thanks
