AC Problems
Hi, If you have verified that the refridgerant level is proper, try a recalibration. SEE BELOW LINK
You may want to try the recal first since it is easier.
Good Luck

Exactly the same out of mine, it all blows cold but doesnt blow hard at all and it doesnt matter what setting its on the air always distributes how it wants. Also i have a leak under the dash. Any advice guys?

Air distribution (defrost, dash, floor) is controlled by vac. Small plastic tube in back of intake goes under batt to inside car.
Any crack, pinhole, etc. in that line will cause the system to lose control of air output.

=================================
Mode Valve
The mode valve in the at-rest (no vacuum) position, allows a blend of air to the instrument panel and the floor outlets; as in BI-LEVEL mode. The mode valve can be opened (full-down) or closed (full-up) by applying vacuum to one side or the other of the three-position mode valve vacuum actuator. When opened (full-down) by applying vacuum to the lower side of the vacuum actuator, air will exit the instrument panel outlets (air is blocked off from entering the floor outlets); as in UPPER mode. When closed (full-up) by applying vacuum to the upper side of the vacuum actuator, the instrument panel outlets will be closed off and air will be delivered to the floor outlets depending on the corresponding position of the heater valve; as in LOWER or DEFOG modes.
Edit-To solow1k water on floor sounds like your condensate drains are clogged up. Should be a Evaporator module drain tube running along the cowl in the vicinity of the ac/heater module. If you can find it snake it out carefully.
