I have two issues with A/C. The first one is that the A/C is colder on the passenger side in the front. The second part is that the A/C in the rear of the vehicle isn’t cold. The air is room temperature and also, I have noticed that the room temperature air does not blow too hard out, but you can hear the motor blowing really hard. I have already done a recharge on the system and have changed the rear evaporator.

The first thing I would do is turn the system on full cold and wait for about 2 minutes and then and then grasp large A/C tube coming from the firewall and the rear evaporator, if there is cold the refrigerant side of the system is working correctly. Then I would replace the rear A/C mode actuator and the driver's side temperature blend door actuator. Here are the locations and how to do the jobs. Check out the images (below). Please let us know how it goes.
