AC Does not Cool immediately sometimes?

My 2002 bmw X5 air conditioner won't stop blowing even while the engine is shut off. It also blows hot air and the led won't go on. I was told that It functions with a code and that I would have to locate it. Was I informed right and if so how do I locate the code?

It sounds as though the AC blower relay is fused.

you need a scan tool to retrieve the code. that will lead the tech to the failure. it is much cheaper to have a shop do it as the scanner runs about 2500.

My A/C is not cold at all anymore, how do I get the chill back?

The system has most likely developed a leak and it will need to be located and corrected then the system evacuated and properly recharged. This operation requires special tools and certifications, are you going to attempt this repair yourself?

Um No, this sounds beyond my skill level. Thanks.

You have chosen wisely my friend. If you need any other assistance, we are here.

My X5 is blowing cool air but not real cold air. Even when I lower the thermostat there is no change. Could the problem be freon like in your home air conditioner?

Thanks.

Why is my bmw x5 4.4 "2001" air conditioner blowing warm air on one side?
Serial Number: lp00021

It is blowing warm and cold because the air conditioning system is low on refrigerant, maybe just several ounces, and that's all it takes.

Yes, it could. Check the high and low side pressures and ambient conditions and report back.

hi....my bnw x5 is overheat and the a/c dont work

The overheating MUST be addressed straightaway or you risk serious damage to the engine. I strongly recommend towing the vehicle to the repair facility of your choice to avoid killing the engine. The A/C issue will require a system check and further testing, but it is probably low on refrigerant and I recommend injecting ultra violet dye into the system to see where the leak or leaks are.

Just recently started hearing growling noises underneath the drivers seat. Not often, sometimes on turns and using brakes. Often when the car is first started, not cold = live in southern ca usually never below 65. Thank you, RanchoPatti

I am not sure if this is something to worry about for now but lets start with inspecting the drive train for any thing loose.

the a/c in my x5 ihas suddenly stopped working. what can i check myself before having to rely on my mechanic?

Was the A/C not working or was the fan not working?

the blower is working but the air is not cooled

Understood and thanks for the clarity. What is possible here is that the A/C system has developed a leak or there are components that have failed. Testing the high and low side pressures is the first step, if there is a leak then this can guide the diagnostic process. Either have this work performed or measure these pressures yourself and report back as soon as you can, I will be here.
