Heater vents
I was messing around with the heater the other day and here’s what happened. When I selected heat the passengers side worked as it should. The drivers side still blew cold air. What’s up with that ???? Worked ok early spring when I needed a little warmth. Anyone out there expirinced the same thing? How can I fix it????!

First of all, what year c5 do you have and does it have manual or electronic climate control ?
If it's electronic then you may have a Blend Door Actuator issue.
You can try the Blend Door Re-Calibrating procedure to see if it fixes the issue.
But first..........Check to see if you have any stored codes pertaining to the HVAC System.
To see all set CODES Turn the ignition key to the ON position, but do not start the car.
Clear any pre-set messages by pressing the RESET button on the DIC
Hold the OPTIONS button down, and press the FUEL button 4 times. This will get you into the CODES section of the DIC. The computer will automatically display all the codes your car has created. It will cycle through each code every 3 seconds.
Once the computer has finished going through all of it's codes, press RESET to enter Manual Configuration mode. It should start with a module and show "NO CODES" or "# CODES".
To optionally reset the codes once in manual mode, press and hold RESET until it displays "NO CODES".
Press OPTIONS button to go to the next module until you reach 99 HVAC
These are the codes for the HVAC Module: 99 HVAC - Heater, Ventilation, Air Conditioning
B0332 Outside Air Temp Sensor Short to GND
B0333 Outside Air Temp Sensor Open
B0337 Inside Air Temp Sensor Short to GND
B0338 Inside Air Temp Sensor Open
B0348 Sunload Temperature Sensor Open
B0361 Left Actuator Feedback Short to GND
B0363 Left Actuator Feedback Open
B0365 Right Actuator Feedback Short to GND
B0367 Right Actuator Feedback Open
B0441 Left Actuator Out of Range
B0446 Right Actuator Out of Range
B1016 Loss of Communications with PCM
U1064 Loss of Communications with BCM
U1096 Loss of Communications with IPC
U1255 Serial Data Line Malfunction
LET US KNOW WHAT YOU GOT, After the code # you'll have either a "C" or "H", example : B1234C and B1234H, C-Current code, H-History, code stored in the past but not present at the moment.
Re-Calibrating Actuators
Use the following steps to perform the calibration update:
1. Turn OFF the ignition.
2. Remove the battery positive voltage circuit fuse of the HVAC Control Module (fuse #27). It is located under the removable floor board on the passenger's side of the car.
Important
The module memory will not clear if the battery positive voltage circuit fuse is installed in less than 60 seconds.
3. Wait 60 seconds.
4. Install the fuse.

From the codes listed, it's pointing to the left Blend Door Actuator.
B0361 Left Actuator Feedback Short to GND
B0363 Left Actuator Feedback Open
B0441 Left Actuator Out of Range
B0361 and B0441 are Current codes stored.
Try the reset procedure first. If it didn't do the job then it has to be replaced.
Brand: GM ACDelco
Manufacturer Part Number:89018365 15-72971
Other Part Number: 52402588 / 16163982
Placement on Vehicle: Left / Right
Or you can go with an aftermarket part:
DORMAN 604-106
