The following may help if you have auto HVAC controls.

Actuator Recalibration

The HVAC control module will relearn the actuator limits whenever power is disconnected and re-connected to the module.

Use the following steps to perform the calibration update:

    1. Turn OFF the ignition.
    2. Remove the battery positive voltage circuit fuse of the HVAC Control Module. It is the radio fuse in the underhood fuse box.

Important:  The scan tool must be disconnected from the vehicle to properly perform the calibration procedure. If a scan tool is connected before this procedure is completed, then new calibration values will not be stored.

Important:  Failure to wait 60 seconds will not allow the HVAC control module sufficient time to clear the old calibration values.

  1. Wait 60 seconds.
  2. Install the fuse.
  3. Turn ON the ignition.
  4. Do not touch anything.
  5. Wait at least 60 seconds.
  6. Turn the ignition off for at least ten seconds but no more than thirty seconds.
  7. Turn the ignition back on and check the system operation.

If this does not work or if you have manual controls the mode actuator is likely the problem and will need to be replaced.

That stoped it from switching thru all the modes and it only on defrost mode now will not switch to any other mode anything else to try
