03 caravan a/c warm one side cool on the other? help plz!
just wondering if anyone had an idea of what would causr my driver side front and back to be warm air, and the pass. side front and back to be cool air but not cold? very strange, i just cant fig. it out. the condensor was just replaced and a recharge kits have been installed with no help, any bit of info would be amazing. the van is an 03 braun entercan, about the same as the sport model with handicap access. of course.
Also try and recalibrate the system and see if it helps. But with the rear doing it too, betting on being low on charge.
STANDARD PROCEDURE - HEATER-A/C CONTROL CALIBRATION
The heater-A/C control module must be recalibrated each time an actuator motor or the control module is replaced. If the vehicle is so equipped, the calibration procedure also includes rear HVAC positions for each actuator motor.

- Turn the ignition switch to the On position.
- Simultaneously depress and hold the Power and Recirculation buttons on the heater-A/C control for at least five seconds. The manual heater-A/C control power Light Emitting Diode (LED) and Recirculation LED, or the Automatic Temperature Control (ATC) heater-A/C control Delay and Recirculation graphics will begin to flash when the calibration procedure has begun.
- The calibration procedure should take less than two minutes to complete for the manual heater-A/C control, and less than twenty seconds for the ATC heater-A/C control. When the LEDs or graphics stop flashing, the calibration procedure is complete.
- If the LEDs or graphics continue to flash beyond the normal three minute (manual) or twenty second (ATC) calibration time, it indicates that the heater-A/C control has detected a failure and a Diagnostic Trouble Code (DTC) has been set. Use a DRBIII® scan tool to perform further diagnosis. Refer to the appropriate diagnostic information. The LEDs or graphics will continue to flash even after the ignition switch is cycled Off and On, until a successful calibration is completed or until the vehicle has been driven about 13 kilometers (8 miles).
the weird thing is i checked the pressure last night and its in the green on the guage, about 35 psi, so i will try the recallibration and see what i come up with. i have another can of 134a i can throw in it, so i guess i will see. thank you for the posts guys, i guess this is a semi-common occurance.
