The way evaporator coils work is they are basically just that, a coil or tubing winding back and forth. When the system is properly charged, the whole coil is active, or cold. If the system is low on refrigerant only part of the coil will be active...maybe half, or maybe even less. The part of the coil where the refrigerant first enters is the first part that will get cold, and the only part if it is low. My understanding of the way the Vette's evaporator is arranged is that half of the coil does the driver side and the other half the passenger side, obviously the first part doing the passenger side. So if the system was low, only the passenger side would cool leaving the driver side warm.

It is because of the way the coil is designed. This is well documented on the Forum. Member DngrZne explains it with this post.
