is does not seem like restricted flow is a problem. the coil its self will restric the blower as air has to pass through it. this is how the manufacture designed it. when you remove the blower door the blower can then pull air through the coil and through the door opening. This is why I am thinking you have more air flow with the doors off.

This is also why my best guess would be that you are draining condensate with the door off but not on. when the blower is pulling through the coil it would seem to be pulling a negative press on the drain and preventing it from draining.

In ealier post others have mentioned condensate trap. I made a reference to it as well. I would start by checking what I wrote a few posts back. If you have already done that try to create a trap with the drain tubing I think you said you had. IIRC you said the drain is in vinal tubing. strap it in a way that creates a trap. If you don't know what is meant by a trap it would be where the tube would drop down at leat 2" and back up at least 1.5" and cause water to stay in the trap area.

Be a good bet that your coil is dirty. You'll need to clean it, but be CAREFUL - don't use a brush unless you are 100% sure of what you're doing. The best way to clean these coils is with a chemical. Some of the big box home improvement stores sell them, but IMO they don't work too well. Better stuff comes from the HVAC supply houses, and you can generally get it in aerosol cans.
