A/C Dodge Ram blows hot

I have a Dodge Ram and my A/C stops blowing cold air when I stop moving. When the truck is moving the A/C works great. What would cause this and how do I resolve it?

Thanks !

Most likely a plugged condenser. Might be able to clean the fins with a garden hose.

Thank you. I cleaned the condensor but it didnt seem to help. I will clean it again perhaps I didnt get in the fins good enough.
Is there anything else I should check?
thanks,
Pete

what year Ram?

some years have problems with the blender door...the plastic arm breaks...had to replace the one in my 99 Ram

My Ram is a 2001. If it is the blender door how difficult and expensive is this to fix?
thanks,
Pete

blowing cold when moving is a fan cooling problem..check to make sure the regular fan and the a/c cooling fan is working all the time...sometimes it stops in motion..check the connectors/plugs or a fuse if its not working
