Have a 2000 vert. When I turn on the A/C the passenger side in noticeably colder. Both driver and passenger control **** are set to max cold 60. Aparently the diverter is stuck in a partial open position. Is there any way to fix this w/o dealer intervention

 

This sounds like the classic low-freon issue. Have your system fully charged and both sides will again be cold.

 

freon was checked all levels ok.

 

actuator motor. do a search on how to fix. ya pull 2 fuses or batt disconnect .the actuators zero out.this may or may not help.for what its worth i sold my 01 coup to a friend and she had drivers side ice cold and pass. side hot with a/c set to max cold.i was going to pull the dash and fix it but one day they went back to norm
