Troubleshoot the Air Conditioning in a VW Jetta : Multi-thousand tips to make your life easier.

A VW Jetta is a family car produced by Volkswagen starting in 1979. Volkswagen is known for producing small hatchback cars, and the VW Jetta was first introduced as a hatchback car with a conventional trunk and some design changes.

This 2- or 4-door sedan, like other vehicles, can develop air conditioning problems after years of use. But before you panic and take your car to a mechanic, try to troubleshoot the problem yourself first.

To learn how to troubleshoot the air conditioning in a VW Jetta, read the steps below.

• Materials that you will need:
  • Screwdriver
  • Replacement fuse, control board, or blower
• Park your car safely. Park your car in your garage, and make sure the transmission is in “Park.”
• Start the engine. Put the car keys in the ignition and turn on the ignition. Let the engine run for 2 to 3 minutes to warm up.
• Turn the thermostat controls. Turn the air conditioning control on the panel from low to high. Observe whether air is coming out of the air conditioning vent. If there is air but it is not cold, the fuse may be faulty. If no air is coming out at all, the blower motor is the defective part.
• Turn the vehicle’s engine off as you make any changes. Whether it is a fuse, blower, or air conditioning panel problem, turn off the engine before performing a replacement or making any changes to your vehicle.
• Replace the fuse. A replacement fuse for the VW Jetta can be purchased from a VW service center or any car parts store. Bring the old fuse with you as a reference when you buy a new one. Sit in the front passenger’s seat and remove the panel to reveal the fuse. Take out the blown fuse and replace it with the new fuse. Move to the driver’s side and start the engine. Let the engine run for a minute before turning the air conditioning controls. Observe whether there is any improvement in the temperature of the air coming out of the vent.
• Replace the blower motor. As with a replacement fuse, you can get the blower motor for your VW Jetta from any car parts store. Sit in the front passenger’s seat and remove the lower foot board. This will reveal the blower motor. Use a screwdriver to remove the screws and free the motor. Take the old one out and screw the new one into place. Turn the engine on for a minute, then turn the air conditioning control on. You should now be able to feel air coming out of the vents.
• Replace the air conditioning control board. Remove the negative battery connection from your vehicle first. Next, sit in the driver’s seat and take out the glove box by unscrewing it from its mount. Keep the screws and use them as you install the new air conditioning control board.

After checking the above steps, if the air conditioning still does not work, it is time to take your vehicle to a mechanic for further checking.
