Enter your car, turn it on and check that the air fan is off. Open the front windows for ventilation and then turn off the vehicle.
Spray the odor eliminator into all the inside vents in your Pontiac Bonneville. Use one or two sprays in each of the vents.
Start your Pontiac Bonneville and put the air fan on high cool. Don’t use the air conditioning setting at this time though.
Get out of your car, close the door and find the fresh air vent located under the cowl in your Bonneville. The cowl is located at the base of your hood, in the area closest to the windshield. Spray the odor eliminator into the vent 10 times. You may have to open the hood to get a clearer shot at the vent.
