Vw Jetta mk2
Hey everyone. I have a problem my vw Jetta mk2 with a TDI 80hp block. His screw keeps turning when I turn on my ventilation. Or when the engine gets hot. I can only make it stop running if i disconnect the battery i can't make it stop turning if i turn off the ignition or turn off the ventilation what could this be? if i turn off the fan and pull the relay out it stops when i plug it in it stays off but it stays the same when i replace the relay. can anyone help me?
