Passat (B6) :: 2006 Climatronic - Cold Air Is Just A Little Too Warm To Be Working Correctly
Oct 12, 2013
I have a 2006 Passat 2.0T (UK Model), and I'm having trouble with both the outside temperature reading and the climatronic's cooling ability. When I bought the car the air-con was blowing cold and warm air without any problems, but the "cold" air is just a little too warm to be working correctly. I've had the system re-gassed but this didn't solve anything.
As I said, all the features of the air-con work perfectly, it's just the cold air just isn't cold enough - so it seems to me that the compressor is working fine. Also, the outside air temperature reading on the MFD reads about 5-10 degrees too warm. Would this have anything to do with the air-con issue?

2010 Sonata, AC isn't working correctly so we added 1 1/2 cans freon. Got the temps down to 40 and then it was running for about a half hour, we started the car after it sat for 20 mins and it appeared that the ac "vented" some freon out. The pressures were 225 high side and 33-35 low side, the ambient temp is around 87 degrees. The venting appeared to be committed no from the lower drivers side condenser. I may be wrong, but never seen this before. Anyway, after it "vented" his ac basically stopped working but the ac gauges still read 210 high side and around 25 low side......

2010 Passat.....the driver seat controller started acting up today...it will not raise or lower the seat any longer ....front to back works.....seat angle works.....front of the seat cushion still works...but the seat height no longer adjusts.

I've got a '06 passat. The a/c was working fine one day, and then the very next day it just stopped. the a/c light comes on when I push the button for it, but it won't blow cold air. I'm not sure if this is a common problem on passats or what's going on.

I have a 2004 Touareg with a 2-zone climatronic system. A while back (hard to quantify exactly), my wife noted that she couldn't ever get warm on her side. I stuck a temperature sensor in the vents and cycled through the temperature settings on both sides. On the driver's side, the air varied with the setting. On the passenger side, it did not.
The absolute biggest problem I'm having, is that here in Florida, I get ice cold air blowing on the bottom of the windshield which causes significant fogging. I can adjust the air to blow away from the windshield, but I obviously get some "blow around" and end up with spots of condensation on the outside of the window. The condensation is almost solely on the passenger side.
I pulled the dash off and replaced the temperature sensor on the passenger side. It actually fixed the problem -- but that "fix" only seemed to last about two or three weeks. After measuring temperatures, the temperature tracked with the setting -- on both sides. Now, the problem has returned and I'm ready to replace the damper motor for the mixing damper on the passenger side. But, after reviewing the eBahn manual, they need the VAS 5051/5052 to intiate a "service position". . . I obviously don't have the VAS 5051.
So, my questions: Is it damper actuator? I also understand the climatronic module "could" be bad. Could the second temperature sensor have actually gone bad? Can the VAG-COM be used to intiate the service position? If not, what are my options?

Car is fully warmed up (200 deg) and the vents blast ice cold air even on 84 deg temp setting. If I put it on hi-temp it blasts really hot air (like it should). Why I can't get in between temps? This has been going on for 3 weeks now but not all the time.

I have a 1999 F250 7.3 Diesel and my AC isn't working properly. On Max AC as you're driving it would be ok and then it would be warm and then cold and then warm and then cold and so on. I've noticed that the clutch stays engaged as well. I've never seen it disengage. The freon is at the level it needs to be. Then just a few days ago, if you have it on Max and High the air disappears from the vents and you hear a noise somewhere in the dash on the passenger side. I think something might have come off?? What's wrong with my AC with it going from cold to warm constantly? I heard that maybe clutch has too big of a gap?? I have almost 200,000 miles on it.

I have a passat B5 2.3 VR5 with aircondition and I have been thinking about to build a climatronic system in the car I did have a climatronic in my old passat B5 V6 TDI and I was so happy about it, The refit part are not the hardest thing, but what about the wiring part? do people rebuild their own wiring system, or is there made a wire kit to the climatronic system.

I have a 1999 passat and want to reset the climatronic. I have tried to press and hold econ and air up together but no luck ...

2007 GS 350 109,500 miles. My heater was blowing cold at idle and warm when driving so I took it to dealer. To my surprise, dealer says its a blown head gasket. No other symptoms. No white smoke, no smells, no warning lights on dash, and running fine. Just had VVT gear recall done last week.
Fortunately I have Lexus extended warranty good thru 125k miles and Feb 2014. I do my own maintenance (plugs, oil changes etc). Have records for all. But have not done coolant change (due at 100k).

I'm new to the Lexus scene, just got myself a gs300 le 2006 - just had it over a week, amazing car but its sounds a bit tappet on cold starts until fully warm sounds scary... noise disappears once it's fully warm.
for a Lexus to do this is a bit disappointed, have searched around can not really find a fix...
It has full Lexus service history, just changed the oil in hope for the noise to disappear... Castrol edge 5w30... no different

I noticed about a week ago (on a cool morning) that my Climatronic system would not blow heat. I played around with it briefly by adjusting the temp settings and how the blower was working.
If I set the temp to High heat would blow out for like a minute but anything else would just blow cold air.
If I set the temp to High and turn Econ on I would get hot Air.
No other settings would generate heat. I VAG Commed my car and there were not fault codes!!!
I took my car to my normal indie shop and they also were puzzled by this. They re-ran a vag com and nothing for them either. The heater core was flushed recently with the resting of my coolant system when my TB was done.
There is no sign of leakage for the heater core but I'm super puzzled to what the problem may be.

Halfway into a 2 hour trip away from home my climatronic died. The display is blank and no air is moving through any of the vents. This was a big problem since I encountered a heavy rainstorm and my only means of clearing the windshield was my handkerchief. I checked the fuse and it seems fine. There was clicking in the dash prior to this happening. I looked at the relay and it seems fine but I wouldn't know what a "bad" relay looks like.

My climatronic/air conditioning just failed on me for no real reason that I can tell. It was working perfectly this morning.
Now, the system blows only warm air, and on the display where it *should* say the outside temperature, it displays "--0" and then the Celsius sign.
This is a 2002 GLX 4mo, if that makes a difference.

I have cut of the battery, and when I reconnected it and turned the ignition on the climatronic display was blinking for approx 10 seconds, and after that worked normally. What could happen to it?

My '06 GS450h has developed a fault where the heater blows cold at idle and low revs but blows warm when driving or revving the engine at a standstill. The coolant hasn't dropped at all and the car never goes above halfway on the temp gauge. Its starting to get frustrating now the cold weather has set in and temps dropping! Long journeys are ok as at high speeds it stays warm but short journeys are uncomfortable!
I just had a feel of the rad hoses and hoses that go into the matrix (engine side of bulk head) and matrix hoses feel warm (both of them), the top hose to the rad is warm but not hot and bottom hose is cold suggesting the stat hasn't opened yet. Its cold outside so getting the car up to temp is quite difficult without a long drive (rush hour at the mo).
Still I just had the car parked on the drive and cranked the heater up to max and held the accelerator for a while and super warm air blows out. The engine cuts back out as "normal operating temp" has been reached for battery mode and then the heater goes cool again! Still the bottom radiator hose is cool and top hose not massively warm. It has never overheated thus far and I drive 150miles a day back and forth to Reading from Cheltenham 4 nights a week.
Only thing I can think of is a sticky thermostat or water pump not operating sufficiently enough to circulate the water? Its getting colder and short trips where it used to blow warm air nice and quickly (within 3-5miles) are becoming unpleasant!

I have a 1983 Volvo GL 240 Auto trans. I've owned this car for a very long time ~20 years and have never had a problem with it. Since mid Autumn this year (currently Winter in Australia) when starting the car after it has been raining, left overnight in the cold or it is a particularly moist day the car will not start properly.
What happens is the car will start and I accelerate to take off the car will lose significant revs, stall and die. If I can get it out from the driveway and onto the road continuously for 5 minutes the car will run fine for the rest of the day.
But if I stop (to a halt) during this period and try to accelerate the car will again lose revs, stall and die. It is very hard from this point to get the car started again as the same thing continues to happen.
I have changed the spark plug leads, engine oil and trans fluid.

2006 F450 6.0 that I've owned since new. It has had 2 injectors replaced previously, EGR cooler with BPD, and a few other problem parts. As it is getting older, I have recently noticed it runs like absolute dog crap when it is cold. It can't even reasonably accelerate onto the hwy when cold. Once it is up to operating temp, it runs better. It still does not pull like it did when it was new and under 50k miles...but it is at least driveable once warm. I need to do some heavy trailer towing soon and need to get this thing back to accelerating good. What should I be looking at first for the horrible running condition when cold?

When car is on , I am hearing a subtle knocking/popping sound I thought was from climate control but not so as even when it's off i hear it. It sounds like a popp noise from maybe passenger side. What component might be doing this?

My climatronic has been goofy since I bought my 2000 v6 4mo. In the winter my heat never got really hot and now in the summer my A/C work sporadically. I had the thermostat changed along with the full timing belt service. I'm hoping I'll get full heat come september. My A/C, however works less and less often. The tech who did the timing belt change etc. said that there was a lot of pressure at the condenser, but that he thought a flap may have been stuck. he checked those and they are fine. The last two things he said should be checked are the external temp gauge(which is way off, reads 22'F when its like 85 out) or possibly I need a new climatronic head unit.
My questions are esentially these; Does the climatronic use the outside temp gauge to determine cabin temp? Do head units fail often? Are there temp sensors in the cabin other than those built into the climatronic head unit?
