Re: air condition sometime don't work.
If you have to hit blower motor to get it to work its probably a bad blower motor....They get water in them a times causing the brushes to rust thus making it difficult to start. Also the motor wil have a kinda grumble noise. Also look in the housing where it sits and make sure its not all wet. If it is, find the leak (probably in cowl area) before u put new one in or you will be replacing it again soon. You can find the leak easy if there is one. Have someone run a water hose on it while you look under there....

Hi, when it comes to vehicle air conditioning I advise taking it to a
professional with the appropriate experience/qualification...I have heard instances of individuals being blinded by freon.
If your blower only works sometimes might be that the compressor has issues.
It could be your blower motor. It is located on the bottom passenger side of the dash board under/behind the glove box. There is a cover you can remove and you can touch the blower motor. once you have the cover off start the car and turn the fan speed to high then try hitting the blower motor and see if you get air flow. if this works you need to replace the blower motor. If not you need a test light and start checking fuses and see if you have power to the motor.
no you don`t need to disconnect the battery to work on the blower motor.just remove the motor and check the condition of the squirrel cage(not damaged) and check inside the air box for debris and clean out.make sure the noise is not the blower motor itself.
Sounds like the terminals are worn out, or have a short. If you can get to the blower motor, try taking off the terminal set, applying some silicon dielectric grease, and putting it back on, making sure the connection is locked down tight. If it cannot be locked tight, try getting a new connector. It could also be a short in the wires going to the fan, or a short inside the fan.
There is a sensor on the side of your blower motor. When mine started acting up I took it to a garage and they told me i need a new blower motor and a new dash board panel. I took it to my "in training" gear head buddy and he replaced the sensor and everything worked fine.
