EXTRACTED KNOWLEDGE / HOW-TO FROM CONVERSATION
QUESTION / CONTEXT: Remeber the vw tiguan that had all the electrical problems? I still havent gotten it fixed. Everything runs fine now minus the air conditioner because the ac compressor is unplugged, it is unplugged because a fuse burns out when we turn the air on. Is it still most liekly the climate midule under the passanger side dash that is the issue ive checked everytjingn else and its the only part i can just replace, apparently vw has to program it
- It had significant water intrusion from clogged sunroof drains.
- Water collected behind the driver's seat, in the spare tire well, and the driver's side seat belts were wet.
- You found the rear sunroof drains plugged and cleared them.
- Since then you've had multiple electrical issues.
- The A/C works electrically until the compressor is connected, then the fuse blows immediately, so you've left the compressor unplugged.
- A/C compressor clutch or control valve shorted internally (most likely)
- Depending on which compressor your Tiguan has, the internal control valve/solenoid can short.
- This is one of the most common causes of an A/C fuse blowing instantly.
