So yesterday the rear ac was struggling with the 100f temp here in albuquerque, this morning it was blowing warm air. Bummer. Went up, pulled shroud, looked in past fan blades and saw some matted dust and other stuff. Took off top metal cover to allow me to get in there and after some vac/suck work with the shop vac and a soft bristle brush it was much cleaner. So did things work better afterwards....yep. Was this due to my not checking in too long....yep. So if you haven't checked that condenser on the inside, better do it soon.
