I bought an 08 Accord coupe and everything has been fine, up until now, that the AC while driving has been shifting from super cold AC to just throwing air. Once I let go off the throttle or I am parked, it is insanely cold, but it seems while I drive, the ac while be shifting temperature or something. From extremely cold AC to just blowing regular air.. Any ideas what it can be?

And my model doesnt have the automatic temperature regular

 

try recirculated instead of blow thru

 

Ive tried both. Nothing
