To remove the air vents on a 2004 Pontiac Grand Am GT, a person will have to pry them out with a screwdriver. Apply gentle pressure between the vent and the dash.
1 of many possiblitesWell depending on what you mean, you obviously can check for airflow the vents with your hand, Is your blower on and no air, if you can hear it but not feel it, could have a blend door issue. cant hear it, id check relays, could be a blower motor resistor block
Check vacuum hoses and diaphrams under dash and at firewall
If your 03 Trailblazer blows heat out of the back vents when set on AC sometimes, it could be because of a faulty blower motor resistor block.
Grand Marquis are designed and wired so that the VAC door fails and will even cause engine not to start due to wires be connected together under dash.
If you are refering to the vents near or on the door try toggling the switches near the steering wheel. One is marked L and the other R. You can move them up or down.
maybe the a/c needs to be recharged with freon
it is the moter that spins the fan that blows your heat or ac out of your vents
Your average A/C unit blows heat through all vents.
The heater may not be on - but the fan still blows air through the vents when they're open !
Usually is a vacuum problem. The vacuum works through the climate controls to make the vent doors open and close.
