Very very good info. Diagnosis steps are accurate and led me to the fix which was the fan control module. Another good hint I learned also is if the fan motors have seized it takes out the control module also. And Thank you!
Id love to see you take the knock off apart and do a side by side comparison of the components just to see where they cheaped out and if its at all salvageable for people that can solder
Great video. Is this similar to a 2011 Volkswagen CC? Currently I’m attempting to diagnose an issue with my AC. The vehicle has good fuses and the fans seem to work when I do an output test with my OBD11. I also removed and put 12v on the AC solenoid that’s attached to the AC and it clicks which makes me think its functioning correctly. Still no AC. I did realize that when I hook up the Freon bottle with gauge, it shows it’s overfilled almost max out. Any suggestions?
You have to check several components. Make sure both fans are on and it’s not suppose to be overfilled. Check to see if the compressor clutch is engaging and disengaging. Make sure the blower is working and it’s blowing air inside the car thru the vents. If all of that is good you might have a problem with other components like compressor, condenser, orifice, valves. Or it might even be electrical. I recommend you look at one of those RU-vid videos on how the A/C works, determine what kind of system you have and go from there.
@@user-eq5ud9tp8o The thick one is the one the compressor sucks from and thin one is where all the pressure goes to. If you turn on your A/C make sure both fans are on. If not, your problem might be the main relay or a sensor that is on the upper radiator hose. It’s round and has two wire connector.
@@mysterygarageCA I know my problem the line that goes from the accumulator to the condenser has a break from rubbing the serpentine belt. Just trying to see if it’s the suction or discharge line on the ac so I can replace it. Oddly there’s no vids or nothing on the topic
@@user-eq5ud9tp8o I see. But they are called the high pressure side or low pressure side. Look it up online as the high pressure or low pressure and compare them to see which one you need.
If your fans don’t turn on most likely is the relay, there is a sensor on the upper radiator hose, that controls the other fan as well. So you have two relays, one is underneath the battery, the main relay, and the other one is under the dash, the fan relay. Don’t buy them on eBay. Get it from dealer or junk yard.
Awesome video just subscribed, I'm a retired Nissan/Toyota tech, got my daughter a bug and man they do things different than I'm used to lol. So my 2001 Bug is having the same issue I didn't start the diag process yet but it sounds like both fans have to be on for the compressor to kick in....and when u say 2 relays u also mean the module correct?
Pin 9 is power coming from the fuse box on the driver side. Open driver door and on left hand side of dash there will be a fuse box. Check fuse #5. Is a 7.5 amp fuse. If it blows again check you pressure switch on the main line behind firewall or the sensor on upper radiator hose. In front of engine.
@@mysterygarageCA You say anywhere but I've searched a lot and haven't found my 2008 Rabbit. My owners manual is not even close to what's in the car. It looks like 16 and 5 but I guess testing all of them would be a start.
