Z4 top does not go up all of the way
I have a 03 BMW Z4 where the top will not go all of the way up. It comes up about 1/3 of the way and stops. When I try to put it back down, nothing happens. I either have to release the red handle in the trunk or wait till it gravitates down. The motor works for 1/3 of the way so I assumed that it was ok, Thanks to the great intstructions posted by shipkiller I removed the top to inspect. The hydraulic fluid in the motor seemed low, so I added fluid but it is still doing the same things. My g/f took it to the dealer and they didnt even hook it up to the pc, I was willing to pay the $105 to see what it would say, they said they know it is an electrical issue because the motor is working to take it up 1/3 of the way. Any advice? I am stuck.
