Well you have to press the button that says off to be able to turn it off.
Why does your ac and heater fan turn off and on
because it is going through defrost cycle
could be a shorted fan,try unplugging the fan and turn on the ac and see if it still blows,dont run it too long with the fan disconnected because the ac pressure increases because the freon is not being cooled.
Check the temp sensor. Also, if the AC compressor is on the radiator fan will be on, so turn off the defroster and the AC.
First check your fuse for your AC in your fuse box, make sure it is good. Make sure your cooling fan is turning on when you turn on your AC, if not it could be your fan relay. If the AC compressor fan clutch is kicking on and off then it just needs freon. If the AC compressor fan clutch is not turning then it could be completely out of freon due to a leak, or you need a new AC compressor.
YOu have your air on to high and the fan is malfunctioning I would turn your ac off
Start out by checking the a/c blower and the blower resister.......
To replace an AC condenser fan, first turn off the power to the unit. Remove the fan guard and disconnect the electrical connections. Take out the old fan motor and install the new one in its place. Reconnect the electrical connections and put the fan guard back on. Finally, turn the power back on and test the new fan to ensure it is working properly.
There isn't one! Insted you go to the factory and get a fan. turn the fan on and turn to the robot.
The ac pump may be seized up.
You can turn the temperature of the AC up but if you turn the fan part of the AC up "high" or "low" it will only make it colder.
Broken fins in the fan or a bad compressor. Or leaves and sticks stuck touching your fan for the ac side (assuming you have a separate fan for ac which you might not).
