Evaporator Core Change

Okay, well day 1 of evap core change is in the books.

It was pretty straightforward. We were lucky enough to find a copy of the FSM online, so any questions regarding order were easily handled. The absolute worst part was getting the bolts that actually hold the HVAC box to the firewall. The only other issue was regarding someone rounding a bolt.

But the new cores are in, and bolting everything up and making sure everything is back in order begins tomorrow!

Looks like the Jeep gods looked down on us in favor today!

We've hit a tiny bit of a snag.

Everything bolted in right and we made sure there was no connector left unsecured.

But... when we started the Jeep, and turned the selector for Recirc, Floor, Defrost, the air never changed to other vents. The knob doesn't seem to turn the same way anymore either, it felt as if it was a little pressurized before so there was a positive reaction to turning the knob. (One positive is that the heater core worked well, cause the air was super hot when we changed the temperature dial!)

We've double checked all the vacuum lines and things seem to be snug and in place.

When we initially unplugged the entire AC control panel, the plug for that switch, it gave off a sound of the seal breaking with a slight "pffffsst" sound. (if that makes sense).

Any thoughts?
