Question 2005 X3 - Air conditioning only cool on driver's side

Hello everyone. We have a 2005 X3 2.5l. Recently, when we turn the AC on, it has only been producing cool air out of the two drivers' side vents. The passenger side appears to be producing warm air. This is a new issue, and it is NOT a dual-climate-controlled car. AC works great for the driver, not at all for the passenger. Any ideas?

Thanks in advance.

Thanks for the quick reply. Ick. I imagine that would be bad, as we're no longer under warranty. Coming up on 90,000 miles here. Any idea of what kind of cost to expect?

Also, seems odd that this would cause just one side to go out, but not the other. Is it possible that this might be a broken switch, fuse, or electrical connection of some kind?

It could be simply low on freon. This is often the case on the E46 3er and the X3 shares almost the exact identical HVAC system.

Agree with AzNMpower32 - whilst in the UK mine was warm on the drivers side it was just low on refrigerant, though the dealer claimed it was all sorts of issues from a 'corroded evaporator' down to a compressor fault. They weren't interested in sticking it on an AC rig to recover the gas and weigh it out so I decided to go to a specialist who did just that, and it only weighed out about 50% of the gas that should be in there.

Bearing in mind mine is a 2004 and had never been recharged. So they pulled the system down to a deep vacuum and left it for 30 mins to check for leaks, and then regassed. There was also quite a bit of moisture in the system which was boiled off when they pulled the vacuum.

Has been fine now for 2 years. The tech who dealt with me said that the system will often continue to struggle with lower gas quantities until there just isn't quite enough in the system to cool the whole evaporator coil, and you get this 50/50 effect because of the way the air box directs air to the vents from the evaporator.

They also added a flourescent dye to the system and I had to go back after a month for them to check for leaks (they also used a 'sniffer' probe too) but there were no leaks, just normal seepage of gas out of the seals which will always happen even though the system is supposed to be sealed.

Hope my experience helps, and don't get fobbed off by the dealer in changing out expensive parts without going to a specialist first. From my experience, the dealer really doesn't know enough about air con to understand what was wrong.

Which means there's a leak somewhere. Tha a/c system is completely sealed and should never lose freon. And yes that behavior is a known thing.
Just take it to a a/c shop, they will localize the leak and tell you what is wrong. It could be just as simple as an o'ring, hose, coupling, but it gets expensive when an evaporator coil, expansion valve gets involved. We can rule out compressor in this case because you are getting cold air from the left side. Depending on the leak, sooner than later it won't cool at all.

If you need parts

I rebuilt my E39 system and this OEM manufacturer had very very good pricing and when they shipped one part incorrectly they overnighted it for Saturday delivery since I was in the shop and down. They had 4 options, brand new, rebuilt oem unit, aftermarket brand and rebuilt aftermarket.

I would give them a call and get pricing.

Question Any Los Angeles recommendations?

Thanks for the advice everyone! I'll definitely go to a specialist on this one.

Anyone recommend someone reasonable that they trust in the Los Angeles area?

My 2004 did the same thing a few years ago. I got it charged at a indy shop and it lasted for about 6 months. I then took it to a indy shop specializing in BMWs (which I should have done to start with). They replaced 2 O rings and charged it up and it's been cooling ever since.

Cool (no pun intended). I haven't had any real post-warranty repairs yet. About how much did they (the second shop) charge for that?

Now that's the sort of thing I can handle. Here's hoping it's something similar for me. [crosses fingers]

Same problem here with our '05. So happy I logged on to the forum first. Now just need to find an A/C specialist in the Boston area. If you know one, please let me know.

Thanks!

Mein Auto: '05 X3 3.0i
My '05 started blowing warm on the passenger side a couple of weeks ago. I only noticed it in the middle of the day when it was really hot outside. In the morning and at night you could barely tell a difference. So last night I picked up a can of R134a, a buddy at work already had one of those trigger-type filler hoses and we added some freon this morning. She's blowing real cold now! I only used about two thirds of the can, I'll wait and see if it lasts. I don't think I have a leak anywhere but we'll see.

BTW... Anyone that want's/needs to know the filler valve is mounted toward the back of the engine compartment on the passenger side, right next to the battery jump-start connections.

Mein Auto: BMW 2006 X-3
My 2006 X-3 with 33,000 miles is leaking at the evaporator. Evaporator located at firewall on passenger side. It's a 2 day repair and the dash has to be pulled. I've seen quotes on other repair sites stating $2,000 to $2,700. Luckily I paid $2,000 for extended warranty so it's covered.
Sounds like many X-3 owners have same problem here. I think they should handle this as a recall. It's not a usual occurance for BMW not to stand by their product.

I just had the same problem in my 2006 X3. Dealer tested it and found leaking o-rings. they made the repairs and charged the system. It is working better than ever now. And the good news is that it was covered under my CPO.

Nobody can push a recall because is not a safety issue, and once out of warranty there's nothing you can do but pay for the repairs. Unfortunately, the complainers are the ones that first come here and voice things like this on their first post and then leave.

But I agree, BMW maybe should look into redisigning their a/c systems, they're prone to early leakeage. I have a 1989 VW Cabriolet that still has its original R12 system, is not the coolest a/c now, but it keeps me comfortable in 100 degree heat. My 05 X3 at 82k miles, still cooling as day 1.

Having the same problem with my 2004 X3. Cool on the left side. We brought it in to the dealer and they said that the evaporator coil is bad and needs to be replaced...BIG REPAIR JOB.

Lucky for us the car is still under the CPO warranty and will only cost us the $50 deductible.

Since the X3 has 80,000 miles on it and the CPO warranty expires in about 1 month, maybe it's time to sell it?

I had the same problem last year. I replaced the shradder valve, recharge the system add freon. It has been working. Cost $130.00 & $150.00
