poss bad blend door?
 

I have been having issues with the ac on my 07 500. I am planning on replacing the scroll valve in the compressor soon as I am 99% sure that is part of the problem. A new problem developed today. This model has the dual climate controls for pass and driver. The drivers side vents will blow cold, but the pass side blows nothing but hot air regardless of the climate settings. I am pretty sure it is a bad blend door but wanted to confirm this with others here who are no doubt smarter than me:)
Thanks!
EDIT: I forgot to mention that I can crank the heat all the way up on the pass side and can tell that it is hotter,all the while having cool air come out the driver side. Crank the pass side back down as low as it will go and it still just puts out warm air.
