I really need some help. I have an 02 Jetta 1.8T. I hope someone on here can help me out. When I have the ac on my fans come on then go off about 30 seconds later. My car keeps running hot and I have no idea what is going. I have replaced the cooling fan control module. Right after I replaced it the fans were staying on while the ac was on but now they are back to coming on and going back off. I don't think that they are coming on at all when the ac is off. Does anyone have any idea what I need to do? I am thinking maybe replace the fan control switch but I would really don't just want to start replacing parts if I don't have to. Thanks.
