A/C makes very loud humming sound

I had used a self charger to charge my a/c and the guage showed that it was good. Now, when I turn my A/C on after a few minutes it'll make a very loud humming sound. Is the compressor going bad?

    I used one of the self charging cans from Checker Auto part. It's supposed to have the oil in it.

When you charged it did you add the ester oil per manufacturer's requirements or did you just add the gas? That sound is probably metal grinding on metal inside your compressor.

humming could be the motor turning round but not engaging with the flywheel. you can check this by hitting the starter with a spanner a few times. if it starts up after you have a sticking solenoid. had to do this a few times my self to get engine started. replace starter as soon as possible if it works. usually happens if you not driven car for awhile.. or you do a lot of starting and small trips.

I have Hyundai excel wen go to start in morning battery some times is dead I have replaced battery same thing also some days jut won't start no spark but lights on dash r on will start after a couple...

sounds like something is draining the battery while parked. was the replacement battery new? get it checked for faults, can happen.. buy a cheap amp meter with a blade fuse probe. remove each fuse one by one and look for high current values while car turned off. this should then give you an idea of what in the car is draining battery, refer to manual for items on fuses. dash lights take very little current to light but to turn the engine takes loads, hence no spark

My front end makes a loud humming noise. At low speeds, I hear a humming noise and at high-speeds I can hear a noise in my tires. Not sure if it is an the wheel bearings, bad tires, or alignement.

Alignment will not create a sound by it's self. The most common cause of humming (especially if you have an agressive tread design)is a wear pattern in the tires...check for that or rotate the tires around & see if the noise changes. If it does then you know it's in the tires. & Not always, but most of the time a bearing noise will increase or decrease in intensity if you load up one side at a time by doing 35-50 mph & turning slightly to each side.

Faint to loud humming noise while driving and turning...

Could be either a loose belt or you are low on power steering fluid,or the power steering pump could just be worn out.

When warm, humming noise from front. engine or transmission

Did you replace the alternator with a new or used alternator? The transmission is controlled by the alternator on pacifica's. Check your caytilatic converter for the humming noise..

Gas guage shows full after charging batery

Did you remove battery cables while charging? Rmove and make sure grd is clean and tight Turn on the ignition, watch gauge. It should reset itself. If not, start engine and drive around the block. then make sure you park on level ground , then shut off the engine. Did that work? If not, disconnect the battery for a few minutes and hook it back up. Last but not leastm go put gas in your tank. It just might be full. Pranks have been known to happen. Good Luck.
