Do you know where I can find a similar procedure and operation sequence for a 95 325iC? My top does not work electrically at all. Just got the car and it's one of the first things I want to troubleshoot.

Sorry, no clue since I do not own a 3-series...

That's exactly my issue. Does that plastic part with the switch inside simply click or slide out of the rear firewall? Or is there a trick to removing it? I've ordered the new switch (minus the plastic cover) but want to take out the part in the meantime to see if can jury-rig it for now. Weather is too nice not to drive around with top down.

Thanks.

The whole assembly is held by one Torx screw. Remove the screw, pull the assembly out and disconnect the switch. You can then take a piece of wire and jumper the socket until you receive the new switch.

I assume it's the lower of the two holes in the plastic part based off of your pictures?
Thanks for the information though, most informative. I would not have guessed at first that it could be this switch. Here's hoping that's all that's wrong with it!

Thanks again!

No videos.

Just look at the DIY's on this site. There are two of them, how to remove the softtop and how to replace the motor.
Pretty self explanatory.

03 BMW Z4 Convertible Top Problem. Don't think its the motor!

Replaced my top last year. Since then top closes slow and It sounds like the hydraulic fluid builds up pressure until it has enough force to move the linkage. Not sure if the fluid needs to be toped up and if this is the case, can it be done without taking the top off.



Thanks

This has been discussed here on several occasions.

But if you think you need more fluid, then you have bigger issues than low fluid.

And, if you find the arm, the switch can be reassembled quite easily....overstaffing the trunk with groceries and stuff can make the deck floor bounce up and down, that switch if pushed the wrong way it is quite fragile.

Awkward spot, I use a very long extension and it makes it easier....also, undoing the flap attached to the floor that moves up and down for the roof space, gives you easy access to the upper screw of the switch.

I want to THANK YOU for all your time...you have helped so many...! I had the problem with the top going down...thanks to you, I lowered the 'floor'...tried again, the windows came half-way down...the top was un-latched and then nothing! so, I put it down myself...but, could not get it to go back up!! I hate to use the 'female' word but I am! I really get into a car and expect it to work and if doesn't...I am LOST! I live in the country so I would have to take my little car there...but, again I sure do thank you for your all you have done for me and others...ps my Dad was a marine aviator in all wars, Vietnam and Korea and the Bay of Pigs...I thank you, Sir!

Top flashed red light and wouldn't go back up

I contacted the dealer and everyone else and they told me I had a bad pump/motor. The first thing I did was pull the switch in the trunk and check it, it worked fine. the next thing I did was find a small guage wire and jump the switch wiring harness to simulate a closed switch. The top worked fine! What turned out is the connector for the switch in the trunk was dirty, not allowing it to make good contact. I cleaned it and haven't had any problems for 6 months! If I would have brought it in I believe they would have gone right to the motor, replacing the switch also. I guess this is the same thing I would have done if I didn't get lucky and jump the harness. Saved $1500.00!
