badblu is on the right track. The 240's have a rubber hose that presses into the firewall like a wiring harness dealy. Without it, the AC condesation tube does not extend past the firewall. It sits low on the passenger side firewall. Either go to Nissan and buy a new one (should be $10-15) or find some sucker at a meet with the hood up. It'll pop right in/out.
