YES, THE LOWER PRESSURE AC PORT IS AT THE PASSENGER SIDE OF THE CAR.
IF YOU OPEN THE HOOD YOU WILL SEE IT , BY THE WINDSHELD WIPPER TANK. ALSO THE LINE AS A BLUE DOT ON IT. AND A BLACK PLASTIC CAP.
THERE IS ALSO ONE BY THE RADIATOR BUT THAT IS THE HIGH ONE.
YOU WILL NEED THE LOWER ,PORT TO FILL UP THE AC UNIT.
ALSO STAY IN THE BLUE , NOT WHITE OR RED. READ INSTRUCTIONS ON CAN !!!
I USED THE ARCTIC FREEZE ULTRA SYNTHETIC 134 A REFRIGERANT. PEPBOY ALSO WALMART HAS IT.
I BOUGHT THE 134 CAN TO FILL UP THE AC UNIT , AT FIRST IT DIDNT FIT BUT THEN IT WORKED. I TRUNED ON THE CAR AND THE AIR ON HIGH.
NOW AM GETTING VERY COLD AIR.I ALSO CALLED THE DEALER AND THEY WANT $ 250 , TO DO SOMETHING THAT YOU CAN DO FOR UNDER $ 15 DOLLERS. THE DEALER DID TELL ME THAT THEY ALSO CHECK FOR LEAKS AND THEY ALSO EMPTY THE AC UNIT BEFOR THEY REFILL IT .
I HOPE THIS INFORMATION WILL HELP , WHEN USING THE 134 A CAN ! YES IT DOSE WORK AND IT WILL FIT .

Porsche Carrera bass speakers inoperative


Either your speakers are blown, you have a loose connection somewhere, or your amp is bad. First thing to check is the amp. If all looks good then you probably need new speakers. Be sure to check all fuses, and, the super simple stuff- like verify the bass setting on the head unit isn't turned all the way down to 0

Bose radio comes on but no sound in my 2004 chevy avalanche.Sometimes even with radio off you hear a popping sound come from speakers. thanks


First Visually check all your fuses. Does rig have amp for stereo by any chance? It sounds like amp is bad and/or fuse is blown. Amp is wired between radio and speakers, and a shorted amp would make crackling in speakers when radio is OFF

Rear speakers go out intermitently and seems like one side may be louder then the other


Do you listen to your music loud? Maybe lots of bass? They sound blown to me. This is a fairly common problem, especially on older cars, since speakers degrade from usage, and hot / cold weather. Good lock!

The sound chip may have gone in the stereo, especially if someone has had it on very loud they sometimes blow, otherwise you have 2 speaker wires touching each other, that way you only get static noise, insidee the door they sometimes come free and touch the body

Check all your speaker wires first.

Front speakers only produce static


The amps are on each of the speakers. There is a place in Florida that will fix them for around $85.00 each plus shipping. I put a sony unit in mine and replaced all of the speakers with the kicker ds series for less than fixing the bose system.

Hey Robert. It could be one of a few things. I had trouble with my speakers too.
If you still have the factory head unit in your car, the static may be because the speakers are damaged.
If you have a new or non factory head unit in it and you have the factory speakers in the car, the speakers will have a static sound when turned up because they have trouble supporting the amount of watts and power that are being supplied to them.
Another problem I think of when you say static is the metal and plastic or your car "rattling" against each other when bass shakes the area around your speaker. If that's the case, you just nee to put something in there that surpresses the amount of vibration that comes off your speaker and flows into the speaker mount.
Hope this helped.
