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.
Your car's defroster may not be working due to a few common issues. It could be a problem with the blower motor, which may have failed or become blocked. Additionally, a malfunctioning thermostat or low coolant levels can prevent the heater core from warming up the air. Lastly, check for any blown fuses or damaged wiring in the defroster system.
A defroster not working in a Ford Focus can be caused by several issues, including a malfunctioning blower motor, a clogged cabin air filter, or a faulty thermostat. Additionally, low coolant levels or a failing heater core can prevent warm air from reaching the defroster vents. Checking these components can help identify the problem. If the issue persists, consulting a professional mechanic may be necessary for further diagnosis and repair.
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!
Check your servos.
thats because your blower went out
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.
