2000 Buick Lesabre Limited with electronic climate control.


Could be a vacuum actuator problem. or just a vacuum leak, period. I have a Jeep that when it has a vac leak, the climate system defaults to the defrost, no matter what you set it at.

When I turn my air conditioner on, the air blows out on the dashboard for the windshield and not from the vents. What can I do??


The blend door actuated by solenoids may not be working correctly causing a/c cool air to come out of the windshield vents, rather than the regular front vents.

I cannot get air out of the mid vent on my 1998 lasabre Limited. I don't think the problem is with the dash hearter a/c controls. Any ideas?


IT IS YOUR BLOWER MOTOR. CHECK TO SEE IF YOU HAVE A FUSE FOR IT. IT IS LOCATED UNDER YOUR DASH. YOU MIGHT BE ABLE TO TAP A LITTLE ON IT. IT MIGHT WORK. BUT OVER ALL YOUR GOING TO NEED TO REPLACE THE BLOWER MOTOR.... JAKE.B

Air keeps changing from upper vent to floor by itself


The vent control works off vaccum from the engine. I would say either the vaccum line is leaking, or the switch to adjust airflow is going bad.

When air switches from vent to floor


Most likely cause is a vacuum leak under the hood. The blower door is vacuum driven and controls air flow inside the car. A vacuum leak will cause the door to malfunction and not direct the air where you want it. Check the vacuum lines under the hood, starting at the firewall and working backwards with the air on and look and listen for an air leak.

Blower motor vent selection switch not working


the hvac selector switch in the dash may be the problem.You need to remove the switch and look at the connector on the back of switch,see if there are any burnt wires at the connector or switch.It's all electronic and the switches have been known to burn out on this and other model.
