The 2002 unit is operated by electric actuators. I believe the passenger actuator is on the right side and the whole unit actuator is on the driver's side. I have picked this up from reading.
I suggest searching further on the net. Also spend some quality time with the hush panels off under the dash and watch the actuators move when you operate the AC control unit to determine which one and where does what... At least you can do this with the key ON and don't have to have the motor running like the 92-99 system which used engine vacuum to operate motors to move vanes and had two actuators for the blend doors (driver and passenger).

The automatic climate system is blowing out hot air on the drivers side and cold air on the passenger side during air conditioning when first started. After a half hour or so the system appears to operate normal. Any ideas what the problem could be?

First check freon level. Lots of folk have found that a low level keeps the part of the evaporator cold that the air that ends up on the passenger side goes through while the part supplying air to the driver is warmer than it should be. '
Second is that there is an actuator that affects the blend door from what posters have said. It is the one on the driver's side. You may have to take off the hush panels under the dash to see. You should be able to move things by adjusting the settings while the key is in the ON position.
#28 of 278 No drivers side AC

2000 Le Sabre with just the passenger side AC blowing cold air. It seems when the AC is first turned on the the drivers side starts to blow cold but turns to warm air. I have read here about thew acuators but for the life of me i can't seem to find what I am looking for. Any suggestions on a fix
FYI this has seperate warm or colder control on the passenger side located on door panel. Freon level is normal.

Thanks for the heads up on the low freon charge. I did not even consider that as the problem, I recharged the system and it works like a champ. Thanks again!

I was experiencing the same issue. Cold on passenger side and hot on the drivers side with the dual climate control system. Thanks to the suggestion of one the on-liners, my problem has been resolved. The AC compressor was not short cycling like they normally do on a low charge, but was running continuously. I had used only the low pressure gauge on my manifold set and it appeared to be normal between 40 to 45 psig, but then after a second look I hooked up both guages and found the freon charge was low and almost flat. I weighed in the correct amount of freon and that has taken care of the problem. I hope this helps you solve your problem!

Thanks for coming back and letting other users know what worked on your car. It will help others.
#32 of 278 2003 LeSabre AC problem, blower works intermittently, dealer can't fix
Sep 30, 2008 (5:11 pm)
I have a 2003 Buick LeSabre with an air conditioner problem that the dealer has not been able to repair.
The air conditioner blower rarely comes on when the car is started but after several minutes, sometimes nearly an hour it will began to work.
On other times when it is not working I can make a sharp turn either clockwise or counter clockwise and the blower will begin to work.
When the blower is not working and I drive over a rough stretch of road it will begin to work.
When the blower is working and I stop the car, the blower will slow down almost to the point of stopping.
When driving and the blower is working, it surges, i.e. varies rpm for no apparent reason.
Once the blower begins to work, it will continue to work until I turn the car off.
Any ideas on how I can get the air conditioner repaired?

Has the blower motor been replaced? Otherwise it sounds like a contact in a connector somewhere along the line. That would require tracing and checking them all.
I recall someone who had an erratic blower motor on the same type car after 2000+
and he tookthe motor apart and found a contact was not quite long enough inside the motor. He rebuilt the contact and it worked happily ever after. He felt the motor itself was poorly engineered and that led to the contact wearing too much too early.
He hiimself is an engineer.
That story is why I asked if you had replaced the blower motor. It's inside the car and removed from under the passenger side of the dash. If I recall it has 5 or so screws holding it in place and comes out with a tight fit but is doable.

No, the blower motor has not been replaced.
I'm disappointed that the Buick technicians have not been able to repair the problem.
Is there some place I can check to see if other owners have the same problem?
