Need to know if the blower is working or not or, the air coming out is cold or warm or hot or, the air (hot or cold) is only coming out the defroster.
Blower motor is shot or a burnt fuse.
Ok..I figured it out. Turns out the rear defroster is the problem. When I unplugged it from the back windshield, blower/heater works great!! So...to all those out there..if your blower motor blows fuses...check the blower motor first...then the HVAC and heater fuses, then rear defroster if you have a cavalier!
thats because your blower went out
Check your servos.
most likely your air conditioner needs recharged per my mechanic brother-in-law
As long as everything is working correctly and clean from the blower motor, the blower wheel, the blower housing is clean, the resistor and switch are working and the cabin air filter is clean if your vehicle has one then you cannot increase the flow.............
the blower motor is going bad it will stop working shortly
Replace your heater selector switch
The air should be comming out of the defroster vents. If so, most likely, it is the vacuum line that controls the vents. It is on top of the engine below the air cleaner, and runs to the front right of the engine. Buy the replacment so you know what your are looking for.
If you are not getting any cool air, the compressor may need recharging or replacing. You will need to call a repairman.
There are some posibilities this are the most normals: 1 - The air blower radiator is licking or not working. 2 - The switch that comands the entrance to the air blower radiator can be broken 3 - You have a air lock and you need to heat your car until your thermostat opens and then take the hose that exits from the air blower radiator valve until hot water starts to come out. ( if you have to replace any of the previous parts you'll most lickly have to do this)
