Climate control distributes cold and hot air at the same time

You should have dual zone climate control,
Check your menu for climate and lower the passenger temp.

Take battery cable off for 5 mins, then put battery cable back on. Insert your key into the ignition turn to on but don't start the vehicle wait 5 seconds turn back off repeat the key on/off three times. This initiates a re calibration of climate control equipment and actuators. It will fix your problem.

Loose or broken drive belt
Inoperative compressor or slipping compressor clutch
Defective expansion valve
Clogged expansion valve, receiver-drier or liquid refrigerant line
Blown fuse
Leaking component: any of the parts listed above or one of the A/C lines, hoses or seals. Most A/C repairs are best left to a specialist repairer or garage. Recharging the refrigerant, in particular, requires special equipment that most people don't own. There are a couple things you can do, however.
First, make sure to have the system checked regularly according to your vehicle's owner's manual - in the Scorpios case that's every 10,000 miles.
Second, if you live in a place with a cold climate, it might not make much sense to run the A/C during the winter months, but many A/C technicians recommend running your A/C system regularly, because it contains a light mineral oil in the refrigerant to keep the compressor properly lubricated. The general rule of thumb is 10 minutes per month. The Scorpio heating, ventilation and air conditioning systems also engage the A/C compressor when the distribution control is in defrost mode.

needs the cotrol panel replaced the climate control is out on drivers side

Just had this happen today to my 2007 silverado heat on the right side cold air on the left side. After engine was off 15 minutes and restarted heat was on both sides. I'm guessing a relay failed to open door to allow the heat to flow thus blowing cold air.will monitor diligently for a while.

The blend door is not directing the proper temperature air to the passenger side.

Vent door between the two sides isn't opening or the flex hose going between the two is off.

problem with blend door either stuck or linkage problem

it is the flap door inside the heater box area.alot of gm with electronic climate control have the problem.there is an actuator motor that needs to be replaced.

you cant adjust it ,this requires the dealers computer to re set it,or a phyiscal control has packed up like a vacumn pipe has split where it pushes onto the valve that controls the flap in the heater unit.
