SilverAccord200

All the sudden my A/C is not blowing cold air. I have the dual climate control system.

When I rotate the temp adjustment ***** the blower will speed up or slow down.
When I observe the compressor while someone turns on and off the A/C switch, the compressor clutch engages and disengages as designed.
Both fans at the radiator are running.

I checked all fuses in both the under hood and interior fuse panels and are good. I swapped "Like" relays in the fuse panel under the hood and no change.

The only thing I have done to this car lately was replace the Multiplex Integrated Control Unit. I do not think, but am not sure, if the MICU controls any A/C functions???

I have not noticed any declining A/C performance. I live in southern South Carolina where using the A/C is almost year around. I do not have any gauges to test Freon but think a sudden change from working fine one day and no cold air the next would not have happen unless something drastic happened all the sudden for all the Freon to leak out very quickly.
Any help or other checks I can perform would be appreciated.
