Z4 Roof problem

[Rob Hyslop]

Z4 roadster roof!
Took the roof out and replaced the motor, replaced the roof and roof only works one way, if I change the wires over in the left rear quarter panel using line out cables then the roof works the other way as if there’s only one supply going to the motor, I have replaced the centre console switch in the first instance but doesn’t rectify the problem, all fuses have been checked and blown ones replaced where necessary. When the roof closes fully there is a red flashing light, the car is a 53 Reg, any ideas? All in all the roof motor works open and shut but only with swapping the wires over.

microswitch under parcelshelf..... it will allow one way movement only (UP) check this is not broken, its in place, and the parcel shelf is in the right position

Hi, thanks for that, I’m sure that switch has to work for up and down as you need to put the rear shelf down to operate the roof?

 

[gookah]

with the wiring as normal, which is the one way the is roof operating? open or close?

 

[Rob Hyslop]

Closing

I still think microswitch then

take the wires off and try it with them separated, and with them joined.
Cant remember if its a normally open or normally closed switch.
