If you are talking about the early 99 which is the MK3 style then I can point to the switch that you are turning on the dash. Poor design which will melt the contacts and cause overheating. You can remove the button by pushing a tab on the bottom and look at the contacts. Turn the switch and push on the copper contacts and see if you get any other speed. Watch out the contacts get hot. The other choice would be the resistor pack located in the heater assembly behind the glove box.

Happy New Year. My name is Phil. My heater for my VW Jetta 1999 2.0 automatic doesn't work. The blower works but not hot air. Blows dirt and part of foam. Did I need a new heater? Or is there something else wrong? Also a clagging sound when I turn the car on but once the car is warmed up the clagging sound stops. The car runs good but worry about the clagging sound. Thanks.
turn your heater on to max heat and high fan. then see if you can feel the hoses on the firewall for heat they should be hot. make sure that the fan unit on the radiatoris working if the upper radiator hose is hot the fans should be running if they are not that means that either the relay is bad the thermo sensor is bad or the fan unit is shot... please rate the solution..........thanks
