Is the water draining out of the evap case good? And how is the flow thru the condesnser? Air flow that is, if you have auto temp control, try this and post any codes.

Electronic Automatic Temperature Control Module On-demand Self-Test
The EATC module on-demand self-test will retrieve on-demand (hard fault) DTCs only, it will not retrieve continuous DTCs. Continuous DTCs can be cleared when exiting the EATC module on-demand self-test. Make sure to retrieve continuous DTCs by carrying out the Electronic Automatic Temperature Control Module - Retrieve Continuous DTCs procedure before clearing any continuous DTCs.
Ã The EATC module on-demand self-test will not detect concerns associated with data link messages like engine coolant temperature or vehicle speed signals. A diagnostic tool must be used to retrieve these concerns.
Ã The EATC module on-demand self-test will detect concerns in the system control functions and will display on-demand (hard fault) DTCs for concerns that are present during the self-test. The vehicle interior temperature should be between 4 C - 38 C (40 F - 100 F) when performing the self-test. If the temperatures are not within the specified ranges, false DTCs may be displayed.
Ã The self-test can be initiated after cycling the ignition switch from OFF to ON. Normal operation of the climate control system stops when the self-test is activated.
Ã To enter the self-test press the OFF and DEFROST buttons simultaneously and release, then press the AUTO button within two seconds. The display will show a flashing blower icon for 20 seconds, after which all vacuum fluorescent segments will be displayed if there are no on-demand DTCs present. If DTCs are present the EATC module will display "00 00" and then on-demand DTCs. Record all DTCs displayed.
Ã If any DTCs appear during the self-test, carry out the diagnostic procedure. Refer to the ELECTRONIC AUTOMATIC TEMPERATURE CONTROL (EATC) MODULE
DIAGNOSTIC TROUBLE CODE (DTC) INDEX and follow the ACTION for each DTC given.
Ã If a condition exists but no DTCs appear during the self -test, GO to SYMPTOM CHART Condition: The EATC System Is Inoperative, Intermittent or Incorrect Operation.
Ã To exit the self-test and retain all DTCs, press any button except DEFROST. The EATC module will exit the self-test and retain all DTCs.
Ã To exit the self-test and clear all DTCs, press the DEFROST button. The EATC module will exit the self-test and all DTCs will be cleared.
Ã Always exit the self-test before powering the system down (system turned OFF). Once the self-test is exited the ignition switch must remain ON for at least 30 seconds to allow the door actuators to automatically recalibrate.
Ã Continuous DTCs will be deleted after 80 ignition switch ON cycles after the intermittent fault occurs.
