heater blowers stopped working ?

[Niall]

Where is the rheostat on a gti6? I thought they ran the blower control from a potentiometer switch? Only reason I ask is my blower cuts in and out as it pleases and lots of people have said rheostat but no one can find it.

The GTi is all controlled from the panel on the dash. Its only the non AC models that had a rheostat which IIRC is behind the scuttle panel. If your fan is cutting in and out, its either a bad fan or bad connection i would imagine
Also, does it turn off completely? Even in the off position they should be spinning very slowly. If it just keeps slowing down, you probably need a new cabin air temp sensor. Same happened to mine when i first got it. Kept going from slow to full speed
