Recirc flap is different than Blend Door -- Blend doors are actually a series of drums that rotate, diverting airflow to the different vent positions and across the cooling or heating elements in the airbox to achieve temperature blend. Recirculation flap simply is open or closed -- open it recirculates cabin air and closed it allows fresh air in.

I was reminded this weekend of the sensitivity of these variable displacement systems to volume of refrigerant in the system, and why just 'topping it off' with a can from Autozone may not help (or be coincidental if it does).

On a recommendation from a colleague at work, I tried A/C Pro Super Seal a few weeks ago. I've been fighting a very small leak in the evaporator for a couple of years, the product was well-reviewed for this type of slow leak, so I thought I'd give it a shot.

Easy -- empty the small can into the low side using the included hose, then immediately charge with r134a to prevent any of the seal from staying in the Schrader valve and sealing it shut. I did this a few weeks ago -- and so far so good. A/C worked OK, but not great, but I knew that there was no way that the right amount of r134a was in the system.

Saturday morning, I went to my friendly Valvoline oil change shop, and had them do an A/C service -- they removed 2.3 lbs of r134a, replaced one of the Schrader valves that was leaking slightly, vacuum evacuated the system, and put in the requisite 1.9 lbs. What a difference that made. System works terrifically now, and we started getting temperatures in the 90s this weekend.

So, my long-winded point is to make sure that your system is properly charged -- even a slight over or under charge can make a big difference in performance!

Good luck!
