I have a bmw z4 that has a convertible top issue. I’ve replaced all my bad switches and no longer have any codes , I clicked the button for the convertible top issue close and my rear windows wend down but nothing else happened. The latches inside the cab are locked and the main windows do not work nor does the latch for the trunk. I found that when I click the button for it to open there is a clicking sound coming from the fuse box inside the cab of the car no clicking from the relays. Have tried to verify that the motor works properly by manually attaching 12v and a ground and verified that it works properly, I checked the voltage coming from my (pink/salmon) relay to the motor and I noticed that I get nothing when I click the button open or close. Do you have any advice on what it may be ? The boot moves freely and can be picked up by hand and so can the roof piece with the back glass verified that the screws are in the correct position on my pump making sure it isn’t bleeding out air , I’m just at a point where I don’t know any more.

Hi, to be honest you are going to get more info and help on the https://z4-forum.com/ plenty of info and a lot of knowledge for e89s
E89s are relatively scarce on here.

3 litre Z3 pretending to be Italian exotica. Two previous E89 Z4s.
If you are up north these guys have a good rep for fixing e89 roofs www.thezedshed.co.uk
That very much depends on who you talk to. Mike at thezedshed caused so much controversy on the Z4 forum that he has been banned for life.

Many reviews say he is good. But many also are anything but good. He does know his stuff on E89 roofs, apparently, but not always the best to deal with.
