The battery change and the problem, may coindental or maybe not, your air regulator door actuator is probably stripped our just worn out, the regulator is attached to the damper that controls the drivers side air over the two coils. shouldn't be to hard to locate, but will require laying on your back and removing the under dash panel. it will probably be a small rectangular shaped module mount to the duct at a damper door! i hope this helps, if you want exact instructions they can be found at alldatadiy.com for 20 bucks. Merry Christmas!

Why does my 2001 buick lesabre blow cold air on passenger side and hot air on drivers side


There should be ( 2 ) slide switches or buttons that control passenger/driver side climate control, one of the switches is not operating correctly and probably be faulty. I have a 1991 Buick Regal with the same problem, sometimes i can slide the faulty one real fast to the right and back to the left and it will work fine.

A/c blows hot air on drivers sde


The actuator door on the driver's side is out of position and needs to be reset. Remove the negative battery cable for 1/2 hour to reset the computer. Start the HVAC system and you should be able to hear the door adjusting itself and cold should come out of the driver's side vent.

Automobile air conditioning on max cool, blows hot air on passenger side tried dual climate control settings still cold on driver hot on passenger


I had the same problem when i was working on my 1999 Buick Regal and had to disconnect the battery. I didn't reconnect in the same way that I disconnected the battery from the terminal and noticed that the driver side had no heat or air but the passenger side did. I then disconnected the battery again and reconnected it the same way and now have heat and air on both the driver and passenger side. Hope this helps. Good Luck!
