Your A/C will not work with to high of pressure. You will need to relieve some. There are easy ways that I’m not willing to put into writing. Then check the pressure while running.

Where do I buy A/C recharge kit for 2004 bmw 325 ci?


Pep Boys, Autozone, Advanced Auto, Napa, most all the major auto parts stores carry a recharge kit...a few Wal Marts even carry them---Or you can buy them online fom Amazon, Ebay, etc...

In most kits you'll find a can of refrigerant, a flexible rubber hose and a pressure gauge. Follow the instructions in the package to assemble the pressure gauge part of the kit. Usually you'll have the hose already attached to the gauge, such as this one.

2004 chevy blazer ac stoped working and if the ac is turned on it stoped the engine abruptly, the pressure on the low pressure port without the engine on reads high at 150psi which is the red danger zone...


I would suspect you have a bad A/C compressor. When you engage the A/C, the clutch locks up the pulley which kills your motor from the drag on the belt. Replace the compressor, evaporator and valve, then recharge system to 55 psi.

Air conditioner blower stopped working on 2004


If the blower works but its just not blowing cold air, its possible to recharge the AC system yourself. Most auto parts stores carry AC recharge kits. Instructions to recharge the AC are belowl

RECHARGING AC SYSTEM

1.Turn the truck on and turn AC on HIGH
2.Locate the low side AC line (will have a valve and cap similar to the cap on a tire)
3.Insert the oil or R-134A can to the hose (Do not turn the screw to puncture the can yet)
4.Insert the other end of the refill hose to the low side valve
5.Puncture the R-134A can with the screw on the refill hose
6.You should feel the system suction the refrigerant out of the can
7.Check for frost on the AC lines and the air blowing inside the truck
8.If frost develops and the air is cold, you've successfully recharged the system and disconnect the refill hose. DO NOT ADD MORE REFRIGERANT...overcharging the system will damage your compressor and will be less effective


Best of luck and enjoy your vacation.
Greg

Hopefully this answers your question and you're able to get your AC working again. Best of luck.

A/c problem.


jasonjacob1 is right. If the air from the A/C is not cool, the only cause is low or empty refrigerant. This means that the gas that your vehicle uses to produce cool air is gone from the system. The solution is not to recharge the system but to locate and fix the leak, then recharge the system.

Air conditioner blows cool air but it does not blow cold air.


Start by recharging your system. If you want to do it yourself. Most auto parts stores and hardware stores have recharge kits. Purchase a kit with a gauge to prevent overfilling.
