Tiguan :: 2009 VW SE - Air Conditioner Compressor Not Turning On
Jun 26, 2014
I have a 2009 VW Tiguan SE with about 85K on it. Yesterday driving to work the alternator/ac belt broke, after replacing the belt the AC compressor will not turn on. The AC was running fine up until the belt broke, so far I have checked all the fuses and the codes, no bad fuses and no codes. I read in the manual about a compressor shaft overload protection but it doesn't go into detail what this is or how to reset it. I could imagine that since the belt broke while the AC was on the system could think there is an issue with the compressor and shut it off but I can't figure out what to check or how to reset it. The AC system was checked a few months ago and has been producing cold air so I don't think there is a coolant level issue.

Just put my car in for it's first year's service(20,000 km). I made an observation to the service tech that during warm weather, there is a noticeable rattling whirring sound.
During testing, they were able to compare my car with another and confirmed the noise to be from the air-con compressor.

I have a 97 Mazda and I notice that the air compressor never shuts off unless I turn the A/C off. I have checked the relay and it is fine. What other control is keeping the compressor clutch from releasing?

I have a 2013 Prius with few miles. It seems like the air conditioner compressor makes a very loud humming noise. It's a little annoying inside, but outside it is really loud. I know it is running off an electric motor and I expect that to make some noise, but this seems excessive. Is this normal? Also, the compressor keeps running all the time. I thought they were supposed to cycle on and off. It seems like all air conditioning compressors do this to conserve energy, even a house air conditioning unit.

l have a 2000 model accent and the air conditioner compressor clutch is not engaging . you press the 'AC 'button and the indicator comes on when a fan speed is selected which l am sure is the correct operation.l checked for 12 volts at the coil terminals of the relay and there is no 12 volts.l shorted the switch contacts of AC relay and the compressor did engage so the wiring from the relay base to the the compressor clutch is ok. l also checked the contacts of the 'AC' switch itself and it seems to be ok. l haven't had much luck with sorting out the wiring from the switch to the relay as l do not have a wiring diagram.

1996 Mazda Protege air conditioner died today in the lovely 2nd week of Kansas heat wave of over 100 degrees each day. Was replaced in 2006.
What should be the approximate cost of the parts and labor to replace? Is it normal to have died after 8 years? It was a reconditioned one.

My Chevrolet 1992 Caprice Air conditioner is chilling but the compressor doesn't disengage when reach the right temperature inside cabin... There seems to be a temperature control or a sensor and I don't know where is it...

101,400 miles on car. Started noticing about 2 weeks ago, at idle, and as pickup up speed, a whining noise coming from the engine bay. It has gotten a little worse, so I started trouble shooting.
Basically, at idle, its somewhat annoying, but as you hit 20-30mph it can be more annoying if the radio is off or at low level. If Im sitting there in park, and its whining away, all it takes is me cutting the A/C knob to OFF, and then quiet as a mouse.
So, other than the compressor going bad, I can't see anything else related? I always hate when AC problems show up, they are never cheap....

Got a 06 F250 V8 Gas. Went to turn AC on the other week & got warm air out vents. Put 1 can of 134 in & the gauge on the "kit" said it was in the green. It was working last summer. You can turn the compressor "face" so it's not locked up, but it's not kicking in. Swapped the replay with another one & the 10a fuse in the fusebox under the steering wheel is good. Is that the only ones? I find it hard to believe that it's something serious. We did change the belt a few weeks ago & I was hoping that we had pulled a wire loose. The vacuum line that plugs into the heater hoses is plugged in.

I have a 2007 Santa Fe. My air conditioner keeps turning on by itself. I press it to turn off, but keeps turning on. I do this several times before it stays off. Then after 10 - 15 minutes, it turns back on. Is this a relay problem or a button problem?

A little over a month ago my battery died and I ended up having to get the battery installed one day and the alternator installed the very next day. After the alternator was installed, I started my car up and when I eventually turned the Air conditioner on, it started making a screeching/squealing type noise. I was first told it was the belt needed some lubrication but that didn't work.
I was later told the ac compressor was bad so I had it replaced. The mechanic thought he ordered a bad compressor so he ordered a new one and installed it....it was quiet for about 2 days but then it started squealing again. the sound was not as bad as before through but it was slowly getting worst. I took it back and he then told me the alternator was causing the problem on the ac compressor so I again I had the alternator replaced....no change. He also replaced the belt and no change. at this point we don't know what's causing it?

So the A/C on my wife's 2013 Tiguan stopped working suddenly this past Thursday, just our luck this weekend was the start of a 95+ degree week. Took it to the dealership today for a diagnostic and they came back saying that the line between the condenser and compressor has a leak and needs to be replaced. They're estimating about $690 including tax for the job, this includes the AC evac and refill.

I have noticed that on my 2012 5.0 Screw that the A/C isn't very cold. It is no where near as cold as my last truck, or any of a number of late model cars I have driven. If it's over 85 and I have it set to auto (70 degrees) it will never get there and just run full tilt the whole day. Even if you select Max A/C and blow it on you you will never have to turn the fan down from being cold as in other cars.

The dealer diagnosed my a/c as needing a new compressor and clutch. I had an a/c specialty shop install a remanufactured compressor and clutch. however, they could not get the compressor to kick on. I checked all fuses (all are good).
I checked the compressor continuity (good, 0 ohms). I checked the plug where the compressor clutch plugs in (it reads 12 volts). the funny thing is, it reads 12 volts anytime the engine is running (even if the climatroinc is turned off). I am definitely not an a/c expert and really don't know how this stuff works.

I'm trying to bring fresh air at ambient temperature into the cab, but even on Econ and Lo, incoming air is a good 20 degrees F warmer than outside, even after 20 minutes or so giving the system time to cool off. The dealer says this is normal. Is there no way to get cool outside air in through the ventilation system without turning on the compressor?

When I am at idle, the compressor keeps turning on and off every few seconds. It seems to work fine while driving. What do I need to do to fix this?

98 e150 - 4.6l, 185k, My air started blowing warm the other day. It worked perfectly fine. I checked the compressor to see if it was turning. Nope! I am wondering if it could be the clutch?
I replaced the alternator and changed the serpentine belt a couple of months ago and noticed a very slight whining sound sometime after I did this. I thought something might be going and just ignored it and said to myself, that's all the new tread in the new belt whining a little. Could be! not sure.
Anyway, where could I possibly start an easy procedure to see why the failure in the compressor not turning? Compressor is a lot harder to get at than an alternator!

Just picked up a 2011 VW Tiguan 2.0t ... Got back into town and ran her thru a touchless carwash. Got it home tonight and the radiator fan ran for over 45 minutes wide open after I turned off the car before I disconnected the battery. The battery cable is off now until morning. Wet sensor?

I just recently changed the battery in my key fob and, after starting the car and driving a few minutes, noticed a flashing light on the dash and the information center stated "AFS turning light malfunction, see manual"...
It has happened a few times since then but have not gotten a chance to see of my turning lights still function at night or not.

I only use AC in the summer around here, not year 'round. When I turn it on, I notice that the engine revs higher when turning the compressor, which cycles on and off. It's only a few hundred RPM, but it's quite noticeable and will make the truck surge forward when sitting at a traffic light. The dealer says this is how the AC works on a GX, so I've gotten used to it.
