Check for a blown fuse.
The legs are rusted off. Is the gas cut on at the meter and on at the heater valve ? The pilot lit and working? Come on down with some facts.
The heater blower may not be working properly. Without the heater blower working, the air will not come through the vents.
heater fan blower motor is burn up not working need to replace it could also be a heater relay typically located on the fuse panel that needs replacing could also be the switch on the switch panel
You have a bad blower resister..............
MAKE SURE THE WIRE DIDN'T COME DISCOBNBNECTED.
Your password is wrong. The right one will work.
Could be, low on coolant, faulty thermostat, plugged heater core, faulty temp blend door actuator.
If a 2000 Grand Am sometimes has the heater blower working and sometimes it won't, the problem could be with the heater relay switch. The heater relay switch lets the heater blower know when to come on and when to go off. In most vehicles this switch is behind the glove compartment. This part sometimes gets corroded from condensation in this area.
when the CPU is working and we get all the data which was in our computer, then we come to know that it is working or not.
It is working. Or U could have used words like: sex. They could have banned u
u need to replace the engine coolant thermostat
Because there's something wrong with it. This is the point where you do a diagnosis to figure out the problem, since there's more than one possible reason it's not working.Not to mention you didn't tell us HOW it wasn't working... are you getting poor air flow, are you only getting cold air, will it not come out of the vents you want it to come out of, are you getting no response from the blower motor?Narrowing down the cause is going to require a bit more information from you here.
