Where is the air conditioning relay located in the FAW-Volkswagen Jetta?
4 Answers
The air conditioning relay of the FAW-Volkswagen Jetta is located below the left side of the instrument panel. The car air conditioning relay serves to expand the control range of the vehicle's electrical circuits. When the control signal of the multi-contact air conditioning relay reaches the specified range, the relay can simultaneously control the opening and closing of multiple car circuits. The FAW-Volkswagen Jetta has a length, width, and height of 4501mm, 1704mm, and 1469mm respectively, with a wheelbase of 2604mm. The car is equipped with a 1.4L L4 engine, featuring natural aspiration intake, with a maximum horsepower of 90ps and a maximum torque of 132nm. The top speed of the vehicle is 181 kilometers per hour.
When the air conditioning in my own Jetta suddenly stopped working on a sweltering day, it was particularly unbearable, so I started checking the relay location. In most Jetta models, the air conditioning relay is hidden in the engine compartment fuse box, usually near the battery or firewall side. I opened the hood and found that small black box—the cover has a diagram labeled with the air conditioning or AC symbol, and its position is quite noticeable. Before pulling it out, make sure to turn off the engine and remove the key. Use pliers to gently pull it out without applying too much force to avoid damaging the wiring harness. If the contact points are oxidized or burnt black, it needs replacement. Make sure to buy a Jetta-specific relay and verify the correct model number. The location may vary slightly depending on the model year but is generally the same. It’s advisable to keep a spare relay in the car for emergencies. If unsure, take a photo with your phone and consult a 4S shop to avoid unnecessary mistakes or damaging the electrical system. Don’t forget to maintain this area regularly, as dust buildup or water ingress can easily cause issues. Driving for ten years, I’ve learned these tricks and saved a lot on repair costs.
Last year, my Jetta's air conditioning failed, which really stressed me out. A friend taught me to locate the relay position. In the left fuse box of the engine compartment, find the diagram on the box cover—the air conditioning relay slot is marked with an icon, making it easy to spot. Make sure the engine is off during the operation, and keep your hands clean to prevent static damage. Pull out the relay and check for cracks or yellowing; replace it if needed, but buy the right model—don’t cheap out. The location is generally fixed near the radiator, but for the 2020 model, it might be slightly to the right—check the manual to confirm. After replacement, test the air conditioning; it’s straightforward, but beginners should avoid forcing it to prevent misinsertion and short circuits. Also, check the fan fuse, as it often fails together. I learned by watching videos a few times before getting the hang of it. I recommend car forums for practical, free diagram guides.
Common issues with the Jetta's AC relay over the years. Located in the engine compartment fuse box near the firewall. Open the hood, locate the box, find the AC-labeled relay, remove and inspect—replace with the same model if damaged to ensure system functionality. Always operate safely with the engine off to prevent risks. The exact position may vary slightly by model but is generally similar. Avoid tampering with other components; it's recommended to consult a technician for thorough diagnosis and repair.
