The fan is no longer working properly. You'll need to replace that unit which actually blows the air through the vents. The refrigerant is more than likely fine. I had my fan replaced by the dealer for $341, but the part was only $90.
Low on refrigerate ?? what does that mean ??
is it just the air conditioning or the whole unit that keeps turning off and on randomly ?
if it is the whole unit, i had this problem also so i done some research and found out that this is quite a common problem. BMW main dealers will charge about £200 for a new unit and that doesn't include installing it.
the problem is a capacitor inside the unit.so privided you got a soldering iron, solder the new component, and know what you are doing, you can fix it yourself for the price of £0.53 the component can be puchased from Maplins and the part number is WW58N. @ 53 pence

I am assuming you want the air conditioner compressor BMW part number 64 52 6 910 458 for a 200 E46 323ci. Open the hood and look at the front of the engine where the belts are. There are two ribbed v-belts coming off of the crank shaft pulley located in the center of the engine down low. The longer belt (6PK x 1538) drives everything else (water pump, alternator). The short belt (5PK x 863) goes to the air conditioner compressor on the passenger side of the engine.
Most likely it is because you are low on refrigerant. Most vehicles have a pressure sensor that stops the A/C clutch from engaging when the 134-a is low. I would take this one to a service shop if you are not familiar with Air Conditioners. It may seem costly but could save you a lot of money if you were to mess things up.
Well, how many RPMs does it vary,and is it a steady drop and raise or erratic? On a Taurus,there are 4 or 5 heater positions that engage the air conditioner compressor.IF the system happens to be low on refrigerant(freon 134) ,the rpm will steadily change a little.don-ohio (:^)
The system may be low on refrigerant, due to a leak, or possibly has a faulty low pressure sensor. If it cycles quickly, I would be lloking for a leak. If it only works randomly, but blows cold when working, possible low pressure switch issue. either way, the system should be checked with a qualified repair shop.
Hi, determine if your car uses R134 or R12 refrigerant. You will notice screw type connectors on the both the High Pressure Side and Low Pressure Side lines in models using R12 refrigerant. R134 compatible models have quick connect valves on both sides. Models made before 1995 may use the old R12 refrigerant. If this is the case, you must have your Chrysler's air conditioning system retrofitted to use R134 refrigerant. Mixing R12 and R134 refrigerants is dangerous and may cause damage to your vehicle.
Check your air conditioning system pressure using an automotive air conditioning pressure gauge. Keep in mind that in order to get an accurate reading, the air conditioner has be turned on the coldest setting with maximum blowing power.
Remove the Low Pressure Side port valve cap and set it aside. The location of the port varies, but it is usually in front of the engine block. Attach the refill hose to the port on the Low Pressure Side of the air conditioning system. The Low Pressure Side port is smaller the High Pressure Side port. Because the ports are different sizes, the refill kit hose should fit only on the Low Pressure Side port. Additionally, the High Pressure Side port will usually have a red cap or be marked with an H or the word High
Allow the air conditioner to **** the refrigerant out of the can by slowly turning the valve on the refill kit hose. Pay attention to the way you hold the can. Most kits will have you hold the can upright when you recharge the air conditioning system. It may take as long as 10 minutes to empty a single can.
Turn the valve to the off position and remove the refill hose from the port. Recap the port before closing the hood.
Let the air conditioner stay on for at least 30 minutes. This allows the refrigerant to move throughout the entire system.
simply "adding a can"is a good way to end up with non-functional A/C. the typical system has high/low pressure switches that enable/disable the system. you need to be at the correct volume of refrigerant as specified on the sticker under the hood. i recommend using the proper equipment, evacuating, pulling a vacuum, and then refilling the system with the appropriate amount.
hey ic, sounds like your refrigerant is low. if you have a low charge it will usually get you slight cool air on the driver's side. have the system checked and make sure you have a full charge. also, be careful about running it low on charge, the refrigerant has oil in it that keeps the compressor lubricated.
