What Ray said, and you might have the ducts knocked off. I would suggest the
dealer needs to look at the job he did to be sure he didn't knock some of
the hoses off.

I do not know how much of a job it is to replace the cabin air filter on
that model, but if the technician must be a contortionist midget, but is
really 6'4", I can see the ductwork getting out of whack and causing the
problem you are having. If the job is as simple as opening an access cover
at the base of the windshield and sliding in the new filter, then my idea
won't pan out very well.

On Ray's point, some cars have a temp setting for the left side an the right
side of the vehicle. If one side is set to hot and the other is set to cold,
then you will get exactly the results you are describing. (I like to think
you woould not be posting this easy of a problem, but it could happen.)

I would be very surprised if the technician disturbed any ductwork when
changing the cabin filter. To change it, open the glove box, flop it down,
remove the cabin filter compartment cover, pull out the old filter, install
the new filter, replace the compartment cover, close the glove box. Not
including the time to empty all the stuff out of the glove box, the whole
process shouldn't take more than 2 or 3 minutes.

The car has a 3-zone temp control system (left, right and rear). Only right side belows cold air.

I would take it back to the dealer and explain that the AC worked fine
before they changed the cabin air filter. Most likely, the knocked
something loose.
