Question about 2001 Volkswagen Jetta TDI
Bad water pump? But with the AC not working all the time I'm not sure. Does the fan always turn on when you turn on the AC? You might want to take off a hose and make sure the T-stat is really opening up and the coolant is being pumped. Just don't burn yourself (remove hose when car off then get it hot with hose aimed at bucket, etc.). Since the AC doesn't work and thwe car overheats it points to a fan problem since thats the only way they are inter-related but some of the other things you mention don't sound like just a fan problem. For instance, the heat should be really hot if the fan isn't working. Heat not working sounds like a bad t-stat or the fluid not moving correctly. Is the t-stat in the right way and you bought the correct temperature one?
The only other thing I can think of is maybe you have the coolant migration problem. In some VWs the coolant in the reservoir gets into the wiring harness at the sensor in the reservoir and travels to all the different electronic systems and screws them up.
