Hot air on drivers side cold on passenger side
SOURCE: Passenger side a/c blowing hot
There's a rod assembly that opens and closes the vents in the car
for the automatic climate control. It's supposed to open all vents to
the AC feed when in AC mode. BUT, if it slips loose, the default
status is to feed heat through (you can open a window in the summer,
but you don't want AC blowing in your face and on your windshield in
the winter). In my case, the driver's side was working right, pumping
cold air, but the passenger side was actually dumping hot air into the
car. Friend who fixed it for me told me he just had to
drop the glove box etc. on the passenger side to get to the rod and
slipped it back into place. I'm not agile enough, but if you are, you
can probably crawl around under there and figure it out - or get a
friendly mechanically inclined young friend to do it for you. Probably
in the mechanic's manual for the Caddy (I don't have one).
Think this will fix it for you - did for me.

The most likely cause of your problem is the blend doors under your dash. If they are not moving like they should it can cause this type of problem. You can look under the dash to see if there are any linkages that are disconnected. Some of these are very hard to change so you might want to take it to a repair shop unless you are very good with cars.

Sounds like you have the dual control. If you have already set the pass side on heat, (With so little infor on these we don't know how much you know) and you are still getting cold you basically have one of three problems.
this will take diagnosis.
hope this helps

The blend door is not directing the proper temperature air to the passenger side.
Might as well replace both sides
