Cold Air One Side - Hot Air the Other!

[Digital60]

I have a 95 Buick Lesabre 3.8 that when running the air conditioning blows out cold air on the driver side and warm air on the passenger side. It has electronic climate control. It used to do it occasionally, but does it all the time now. Seeing how is was 111 in Phoenix in May already, I would appreciate any help for my wife's car! Thanks!

I would first start by checking the vaccum line from the engine to the firewall. Make sure there are no cracks and that there is a vaccum on the end of the line. If that looks okay. Then you may have to re=move part of the dashboard and check the accutators. Could be broke or just unclipped. This is a some what common problem with the Automatic Climate Control. I do know they have diffrent types of acutator setups.

Same problem with my Climate Control. It was the actuator motor under the passenger dash.

I appreciate everyone's feedback. I'll check hoses and the motor. Do you take out the glove compartment, or does part of the dash have to be removed?

Mine is a 2000, but I would think the AC & heating configuration is the same. With mine, the glove compartment or dash did not have to be removed. Check to see if there is a panel located in the passenger footwell, under the dash. If so, the actuator motor should be there.
It could be the motor itself, or the flap it controls could be binding.
