But, it's still blowing cool on the driver side. I understand that this likely means I need to recharge my AC. That wouldn't surprise me as it has never been done in 9 years of ownership (69k miles). Is this a DIY task? If not, should I go to the dealer or a shop specializing in AC service/repair?

 

Do a little research here on the hvac plenum blower doors.

 

Is this a common problems that Dodge doesn't fix? Mine does the same thing!

 

Blend doors are an issue on these wonderfully designed specimens. Break all the time. If you have warranty Dodge will fix it but like a lot of us proud Dodge owners they hung us out to dry with junk and we had to fix them. Lot of info here how to do it. I used Heater Treater years ago. Better than replacement Dodge crap, easy and one more issue I gave Dodge the finger on.

 

Could be blend door but it is a common symptom for low refrigerant to blow warm on the passenger side. I'm going to try this first before doing anything else. I just wanted to know if it's fairly easy to add refrigerant myself or is it better to use the dealer or an AC shop.

 

Sounds like a low refrigerant issue especially if the air flow exiting the registers on both sides is the same. I believe it is a best practice to have an independent shop perform the service. A trained technician with the proper equipment can have the system operating at it's best.

Most of the refrigerants sold in little cans contain stop leak. Many people use the small cans with stop leak and perform the procedure incorrectly. After failing to gain anything by adding a can or two, the vehicle owner takes it to a shop to have the techs perform the evac and refill process correctly. However, these stop leak products can and will plug up the shops a/c equipment.

 

Great advice! Thanks .... will take it to an AC service place.
