First thing to do, is check your fuse box. Look in manual where it is. It normally could be a fuse that has blown. Next step would be wire short going to the fan motor and last step is fan motor went out and needs replacing. Check fuse first.
SOURCE: where is the ac refill hose on a 2003 chevy impala
Follow the ac lines from the ac compressor,and look for the large line,it will have the ac service port on it,it will be the only one your charge hose will fit,if this was helpful,please rate,thank you.
SOURCE: Impala has dual climate control. AC blows cold on
with a dual climate control system, it is imperative for a proper refrigerant charge to be maintained. the symptom you describe is a possible indicator of low charge on the system. the ac evaporator core is closest to the right side of vehicle thereby making air feel cooler on that side, on the left side of the vehicle the cooled air has farther to travel and warms up from cabin air before it discharged from the vents. this is the most probable issue for your vehicle...however if the charge is accurate, the issue would be more so in the air temperature doors which is located deep inside the dash...i hope this helps...good luck!

SOURCE: 2005 Chevy Impala driver's side heat blows cold.
First....buy a drivers side air flow actuator at a auto parts place for dual zone heating/cooling.
(NAPA etc will have it.....or the dealer)
Open the glove compartment.....all the way....you may have to take the screws out at the bottom......look in at the heater assembly....look over to the left....you will see the two air flow actuators.
Look at the part you have and match it to the part on the heater assembly.
The actuator that is closest to the engine is the drivers side control.
Replace it.
Try your controls and check for heat and cooling on both sides.
The stepper motor in these actuators goes bad on quite a few...but over look that.....you have a great car,good for many miles of trouble free driving.
