REPLACED EVAPORATOR, NOW ONLY DEFROST.

I had to replace my evaporator (and heater core) this weekend. Air nice and cold, but only defrost. It worked fine before I pulled the heater box.
I have vacuum going into the firewall (right past the check valve).
Without starting I disconnected the vacuum line after the check valve, heard vac for a second and stopped, bypased check valve, no difference.
The I disconnected the vacuum block connector under the dash, started the truck, had strong vac for 2 seconds and died down to nothing.
Pinched line maybe?
Assuming I pinched the hose somewhere, where could I run a new hose so I don't have to pull out the hole box, again? What size hose?
Thanks for your input.

That's exactly what it sounds like, a pinched hose. You can run one anywhere through the firewall. Exact hose size, good question. Chrysler uses some rubber hose, some plastic. Take a section with you to the store to match it.
