Heat and air

Asked by Charity Jan 06, 2019 at 11:53 AM about the 2004 Buick LeSabre Custom Sedan FWD

Question type: Maintenance & Repair

My heat and air conditioning are not blowing out any air.
The air is cold and heater is hot. It's just not producing any
air other than the vent when driving down the road.

It sounds as if the blower motor quit, check fuses then check the motor itself by disconnecting the connection then put a test light on the motor wire and ground if it lights replace the motor if not look at the switch next, just a note, when the resistor goes bad high speed will usually continue to work.
