I applied vacuum to the recirc connections. They are tight and I can hear actuation. I then looked at the test procedure on the CD so the next thing is to apply vacuum at the firewall to test the one way valve and to see if the manifold is applying vacuum as it should according to the test procedure.

So far there is no indication that the instrument panel will have to come off. The recirc pods seem okay and connected, so it could be the one way valve, or maybe the PCU itself.

Wish me luck,
