Some Dodge Dart owners report experiencing issues with the sunroof where the auto and vent buttons are not functioning. These problems may stem from electrical issues, as some users have checked the wires at the sunroof switch and found correct voltage readings, yet the vent button fails to operate the sunroof. Additionally, some owners find that recalibrating the sunroof can help, particularly if it does not close completely or stops unexpectedly; this involves a relearn procedure, such as holding the close switch until the sunroof is fully closed. Furthermore, a malfunctioning sensor may be indicated if the sunroof does not cycle through its positions when the close button is held down, potentially requiring sensor replacement. Lastly, while not always necessary, accessing the Sunroof Module with diagnostic tools can assist in retrieving codes for effective troubleshooting and repairs.
