92 Buick LeSabre Blower Door Closes after 15-20 minutes


I'm fairly sure that model still uses a vac control for the hvac. You may have a vac leak in one of the lines, the main controller, or one of the blend doors. The blend doors are under the dash and may be difficult to reach.

Blower motor won't run on 2005 buick lesabre


There are two fuses on that circuit I believe. There is one labeled HVAC CTRL and HVAC HI, both should be located in the fuse block inside the car. Check both of those and make sure they are good.

As well, there is also a blower motor resistor that is located in the blower motor housing. Its very common for these to go bad and can cause issues with the motor not operating as well.
