Dehum is short for dehumidify. This setting is to remove the humidity from the air without doing any real airconditioning. Also, if the a/c is spitting water out the front, then the a/c is leaning forward too far. The a/c should be at least level or maybe leaning toward the outside a little bit to help facilitate drainage.

You should check the 30 amp "RDI" fuse and the 7.5 ECU-IG fuse. Both fuses are critical to the operation of the fan system. The RDI fuse sends power to the fan #1 relay. The A/C amplifier turns on power to the fan #1 relay, this is why your fan works on A/C.
Now, with no cooling fan under "normal conditions" (A/C off), you need to have a good fan #2 relay, and a good water temp switch. This switch is on the engine, near the thermostat housing (I think); with a single plug, with a white with a blue trace wire going to it. Remove this wire from the sender, and jump it to ground (anywhere on the metal of the engine) with the key on (engine OFF). If the fan starts, you need a new water temp sending unit. If not, then consider a new fan #2 relay. This system is pretty simple.

If it is blinking it is in a 5 minute time delay.
It should settle to a steady snowflake after 5 minutes and come on normally.

Mine does the exact same thing. If I turn it off for a few minutes it will work again for about 15 minutes. Doesn't matter which area I select the air to come out. The fan blows hard but very little air comes out.
