Electric roof mechanism

Post by Z3andZ4 »

Hi there

Can any helpful person share with me an idiot’s guide to trying to find the fault on my electric roof not working please?

Where do I start?

I know there’s a motor in the boot and an on/off switch incase it fails so it can be used manually, but that’s about all I know.

Any kind expert able to offer me any assistance please?

Thanks
Neil

Easier to give support if you mention what is not working. Motor totally silent and dead? Have you checked the fuse and so on.
One common problem is the microswitch in he softtop is broken, the one that checks if you have lifted the front end manually.

Bit tricky for me to check everything at the mo as still got the hard top on!!!!!!

Wasn’t expecting such a rapid reply 😉

Am reluctant to take hard top off too soon as it always takes me a couple of weeks to secure it so it doesn’t leak. I put the hard top on and then a few weeks later tighten it and a few weeks later fully tighten it for tightness.

If you have a hard top you will know what I mean. I use the gummi pheldge stuff.

Actually, I have no problem to get the hardtop tight. Maybe leaking a little at the top front of the side windows. But it is plenty of adjusting possibilities.

The micro switch is placed in the soft top frame, left side just above the side window. In the spot where the front part is bended upwards when lifting it manually to make the motor start. But you need to close the softtop to reach the micro switch. But I assume you know that you can open a valve at the pump and do it manually.
Test micro switch by using a multi meter. Circuit should close when lifting the front part of the soft top.
You can also short that circuit. Important, start lifting the front before pressing the button. If it works, change the micro switch. If broken, go for an origin. It is expensive, but too much job to make some sort of copy to fit.
That switch has been changed twice in my Z3. If the switch is broken, please come back for some good advices how to make it simple.
