Hello, I have searched the forum with no success on the issue. I apologize if this specific issue has been covered. I have a 2001 tdi golf in which the ac has worked great for a long time. My fans quit, I replaced them, they worked, ac still worked. Fast forward 6 months. Now when the car is running and you activate the “ac” button, the ac compressor will engage for approximately half a second and disengage for roughly a second. It will fast cycle about 6 times and will not try to engage again until the car is shut down and restarted. Then the same. I then noticed the fans aren’t running. I replaced the fan control module with a brand new made in Hungary unit. Nothing changed. No fans. Same fast cycling. I have a 2001 tdi Jetta, ac works well in it. With the car shut off it has the same pressure as the golf (high and low side equalized) which tells me it has at least very close to the correct amount of refrigerant in the system. High side gauge barely increases when the pump cycles and the low side barely drops so it shouldn’t be an under/over pressure situation right? I am a couple sweaty days away from relays and toggle switches for fans and compressor. But I hate to void oem function. Thank you in advance.
