If you have separate heat/cool selections for the driver and the passenger, you have two blend door actuators, otherwise just one. You also have a mode door actuator, a recirculating door actuator, and possibly a defrost door actuator.

SOURCE: cold air on passenger side warm air on drivers side

Actuator motors either get a tear in the rubber or a hose is broken and not letting vacuum assist in its opening.
You can try moving the lever by hand and see if the air gets colder on the bad side.c976077.jpg

Is there a way to electronically reset the blend door actuators on my 2005 buick lesabre

Did you replace them ? If not working correctly you probably need to replace it. Do you hear a clicking noise behind the dash ? Does your buick have manual or automatic climate control ? You say blend door actuator ? right or left ? Or mode door ? Mode door would be for moving from floor to vent to defrost . Blend door actuator is Temperature Valve Actuator right or left side.
After replacing one , their is a Actuator Recalibration that must be done . One using a professional scan tool or one that doesn't need a scan tool

Calibration Procedure without a Scan Tool
Turn OFF the ignition.
Remove the battery positive voltage circuit fuse of the Instrument Panel Control Module.
Important: The module memory will not clear if the battery positive voltage circuit fuse is installed in less than 60 seconds.
Wait 60 seconds.
Install the fuse.
You probably don't know where the I/P control module fuse is ?
Fuse is located under the rear seat , left side . Fuse # 37 10amp . HVAC (BATT) .

Replacing blend door actuator for 2005 buick lasabre

2008 Lacrosse

Condition: no heat.

Diag: Hot In and Out hoses radiator, hot in and out to Core which means fluid good and thermostat opening. Bled air out of thermostat.

Fix: while listening for click of BLEND DOOR ACTUATOR (Electric CONTROLS) I manual set temp cold to hot back and forth. HEAT now.

Reason: COVID from sitting almost two years due to not needing three cars commute (WFH) since COVID.
Guess they got stuck from sitting there. I kept telling everyone to "exercise" their cars every week or so by driving and not just starting them.
