('89 XJ, no A/C)
I recently had the vacuum leak at the bottle in the bumper causing my heat to only come out of the defrost vents. I took a look at the vac lines and the hard lines were all extremely hard and cracked so I broke them back to the part where they were flexible and rerouted everything - now I get air coming out of the front vents. But here's the catch.
On "Bi-Level" mode, I get most of my air on the lower horizontal vent in the center. Then there's less air coming out of the left driver side, even less coming out at the feet, and no air coming from the passenger side vents.
Also, the Heat mode seems to redirect air.. nowhere? It doesn't come out of any vents that I can find. The vent mode works just as the Bi-Level except none comes out of the bottom. (Expected).
So here are my questions,
where does the "HEAT" mode direct air to?
Why would there be air coming out of some vents but not others? I suppose a line could've come off of the vent.
Also, I noticed that the pinkish vac line coming from the firewall and ending up at a valve for the coolant coming into the heater was broken. As in, it doesn't connect to the valve anymore. It doesn't seem to affect anything that I know of, and when I jimmy'd it back on, the valve didn't seem to move at all with any of the different heat modes.
Thanks!
