A/C Blowing Oddly in my 03 Mountaineer!

[cedarwoodron]

I recently added refrigerant to my a/c system, as it had been blowing lukewarm. Then, yesterday, the drivers side and the left center ports were blowing warm while the passenger side center and passenger right ports were blowing cold. Any one have a clue on this???

Thanks in advance for any advice.

I had the same problem with my '03 Explorer. Add more refrigerant.

It could be low refrigerant, and it could be the blend door. You should check the refrigerant charge with gauges before throwing more into the system.
