Question about 2001 BMW 325

1 Answer

A/C died after detailer pushed A/C button off then on again. Local repair shop diagnosed bad compressor. Compressor changed, but cannot get low enough nor high enough pressure reads after re-charging with refrigerant. Noted same problem with hotter air out of right side of mid-dash vents. Any suggestions for myself and my local shop?

    the local shop figured it out. the return hose was damaged on the inside (no external evidence of damage). Thus the coolant was not getting back to the compressor, which then burned out. New compressor + New hose = Cool in California!

Hey,

I recently purchased a BMW 325i, I've been doing alot of preventative maintanance on it and found your problem might be related to an old environmental air filter located under the hood compartment, It's located under the hood vent up near your windshield. There are 3 twist pop up latches, lift the front of the cover up and pull toward you, be very careful to turn the latches in the correction direction, they look pretty easily broken if turn in the wrong direction. You have 2 choices of replacements... Charcoal filtering or plain mesh filtering... Depending on your local environment I would get the Charcoal filter... I think it would last longer.

Well good luck and good driving.

Sincerely,
325idegrees

I bought a new ac compressor but my ac still doesn't work, I can rig it to where it would be cool air but how to fix it to where it is suppose to be and the ac works with the air compressor?


your best bet is to have a qualified repair shop look at it . Can't tell you from here , you don't even say what make , model or year it is . The A/C compressor isn't tuning on when you push the button , correct ? When you push the A/C button it sends a signal to the BCM or PCM ,which then energizes the A/C compressor clutch relay . Who replaced the compressor ? Was there a vacuum pulled on the system ?

Why does the compressor for the ac on my 2003 ford focus keep clicking ?


I assume it's because your clutch is engaging and disengaging. Could be from a loose electrical plug to your compressor coil on the compressor. It could be a loose plug to the pressure sensor or a bad pressure sensor because that sensor will shut it off if the car is low on Freon causing low pressure in the system. Could be low on Freon so it's on the edge of having enough pressure to turn it on and then shuts it down again because it dips below the pressure threshold when the compressor kicks in. Could be a bad compressor coil that engages the clutch. Maybe a loose connector to the AC Button in the car or the AC Button is intermittent. Could be an intermittent relay engaging the compressor clutch. That's a good list of what all could cause it and if you end up needing to replace the compressor, I made a video on how I did it.

What's your problem?ac compresor seems like dont recive energy


There are 2 safety switches in most A/C systems. A high and low pressure sensor will cut off the Compressor clutch. You can borrow a gauge set, called Manifold gauges, from tool loaner programs at Autozone, Advance, or Oreilys autoparts.

There are several ways to try to fix this. It depends on what the pressure gauges show.

If the pressure is low, but not empty, there is hope. The old Freon leaked out. It will happen again. But there are products which can plug some leaks. Then add Freon using the gauges. The ideal amount is an amount that makes the compressor stay on the longest. There are gauges that can tell you, color coded, and reasonable priced.

If the system is completely empty, it is contaminated with outside air. The Freon will not function correctly if added and a new Dryer(A/C part) should be installed. There is a Vacuum pump which must be attached to draw down the system to a negative vacuum. So even changing a part will not decontaminate the system without the pump. Pump can be loaned from Autozone with big deposit which is returned, no hassle. Some parts require special pliers and "O" rings to reinstall.

The price of Freon has skyrocketed. What once costed $12 to refill a car now costs $50. So going to a repair shop can be a better idea if you waste Freon doing it yourself. If you don't repair the leak, imagine $50 evaporating into the wind with the Freon.

Blower for air conditioner works but no cold air comes out


it sounds like either you a/c compressor isnt working properly of you have a leak in the a/c system causing a loss of refrigerant. a way to see if your compressor is working properly is to open te hood and have someone sit in the car with the key on engine off and have them push the a/c button on and off. you should hear a definate click coming from the compressor. if you dont hear a click it would be because your compressor failed or there isnt enough refrigerant in the system for the compressor to come on. there are two pressure switches a low pressure switch that tells the compressor to come on once the pressure drops to a certain point. and a high pressure that tells the compressor to shut off once it reaches a certain pressure. you can try recharging the system yourself by going to your local auto parts store and buying a recharge kit. this may solve the problem but if it leaked off once, chances are its going to do it again so i would take it to a shop and have them test it for leaks.

Hi, no, they are not related. The oxygen sensor(s) are part of the ignition/emissions sytem and help regulate fuel flow/mixture. The A/C system is self contained and does not affect other engine systems. Mike

I have a 1997 Saturn SL2, I was told my compressor is bad because it won't hold any freon but now it is making this annoying noise. Is it because of the compressor or are my belts going bad?


We don't have your car to examine & answer that question

Have it checked again and repaired at a local shop
that does A/C work. Not all repair shops do

Ac compressor will not kick in unless i ground the green wire to the low pressure switch when i do this it kicks in and works great


You are bypassing the safety mechanism built in to prevent compressor damage. You either have one of two conditions, You truly have a low pressure condition(menaing you need an evac and recharge(fill the system with r134a gas) or a bad pressure switch. The switches are inexpensive replacing it will cost less than the charge to diagnose it, as such i would have it evacuated change the switch then have it recharged and a UV die added in so any other potential leaks can be found

My AC suddenly stop working, I was driving and the AC was running but as I said it just start blowing warm air


Your A/C system may have lost its charge of refrigerant, or the compressor may not be engaging when you turn on the A/C, or the blend air door inside the HVAC unit may be stuck in the HEAT position so no air goes through the A/C evaporator.
Start with the compressor. Does it engage when you turn on the A/C?
If so, the compressor is working and the A/C system probably contains enough refrigerant to make cold air, so the problem is inside the HVAC unit. Replace the motor that controls the blend air door (this is a difficult job and best left to a professional since it involves tearing apart the HVAC unit -- about an 8 to 10 hour job!).
If the compressor does not engage when you turn on the A/C, see if it will run by jumping the compressor clutch wire directly to the battery (use a fused jumper wire). If the compressor works when you jump it, and the A/C blows cold air, the system contains refrigerant and the fault is likely a bad A/C compressor clutch relay or a bad clutch cycling switch or pressure switch .
If the compressor does not engage when you jump it, the problem is a bad compressor clutch.
If the clutch engages but the compressor does not turn (the belt will start to slip and squeal), the compressor is loced up and you need a new compressor.
If the compressor clutch engages and turns the compressor, but the A/C still does not blow cold air, the system is probably low on refrigerant and needs to be recharged. If you Have an A/C gauge set, hook it up and see if the system has any pressure.
If it is out of refrigerant or is low, check for leaks, then have the A/C system vacuum purged to remove air. After the air is out, it can be recharged with the specified amount of refrigerant. It is important to get any air out as this will reduce cooling efficiency and may make the compressor noisy.
My advice to you if you know nothing about A/C service is to find a repair shop that specializes in A/C repairs and let them fix your cooling problem for you. Today's A/C systems with automatic climate control are very complex and reuire special tools and know-how to diagnose and repair.

A/c compressor continues to cut off/on.Full of


so, basically the compressor still WORKS, but it cuts off and on? they cut off and on alot anyways, but i would say, if it works, you shouldnt have anything to worry about, unless its doing it at ridiculous intervals....in which case you'll want to take it to an AC repair shop, and have the system checked for leaks, and possibly have the system evacuated and flushed.....there might be a valve that is stuck, which would cause the compressor to act erratic, otherwise your drier or evaperator could be clogged.

A/C blowing hot air. Compressor activates and system has pressure.


Could be the expansion valve. That's what allows the temperature to actually drop in the system - the contents of the AC system are under pressure, and are at a certain temperature. When the freon goes through the expansion valve, the pressure drops suddenly and dramatically, which "flash chills" the freon, allowing the air to blow cold. If it fails, you may get lukewarm air from the AC despite everything else working. Also though, check to see whether the AC evaporator fan (underhood) is working - on some cars, if it doesn't turn on, the compressor won't be run enough to cool the air.
