Air not blowing out vents

[Kylec345]

I have an 85 cutlass and the air is not blowing out the vents and not even the defrosters also the passenger side floor and rear passenger floor are soaked with this oily substance any thoughts on these two?

Check for leaking heater core and check for vacuum lines disconnected underhood @ the reservoir ball

There are 2 spheres under the hood which one would it be? My guess is the closest one to the firewall?

Mine mounts next to the drier for the a/c on the same bracket. And has 2 Hardlines for the vacuum. Both are sort of a gray and very brittle .

Dip a piece of white paper in the liquid. If its green, its coolant and your heater core is bad. Its not hard at all to replace, it's all underhood. If you didn't have the liquid issue id say your vacuum lines are damaged or missing, but start with the heater core first.

2 issues, vacuum problem and probably a leaking heater core
