You have a vacuum leak.Defrost is the default postion(no vacuum).
See if you can locate the small black vacuum line that goes inside the vehicle on the passenger side near the heater core. The trace it back,should see it going to a canister then to the intake manifold.Make sure it is not disconnected or broken somewhere.

Does the engine crank but just not start? Or... are you cycling the ignition switch without trying to crank the engine? Based on the information you have given, I would first guess that the fuel pump may be going out. I say this because when you first turn the key on the pump primes the engine with pressurized fuel. If the pump is getting old, it may take a few power cycles to get it going. You can test this theory by having somebody listen near the rear of the car while you turn the key on for the first time. The fuel pump make a faint, yet distinctive high pitch noise that can be heard when you turn the key on. Try that first. Next thing you would try is checking the relays for proper function... starting with the fuel pump relay. Good luck.
