Convertible top stuck open

Looks like a failed relay:
"I sat in the car and started pushing the roll bar button. We heard a click every time I pushed it. My brother was at the back of the car and was trying to hear where the clicking was coming from. He realized it was coming from a relay switch so he took a screwdriver and tapped the top of the relay and **BAM** everything starts working! So through that we realized it was a bad relay".

I would call the dealer on this, but I'd guess yes.

The control module has set a fault and it will have to be reset. They are sensitive to voltage & must have 12 volts to operate properly.
The windows and top will need to be resync. I cannot find any information regarding the diagnostic procedure for the roof .. it states there is a procedure to diagnose the fault with the number of flashes the switch makes .. a dealer may be your best option on this fault .. I hope this helps some.

hi its just spring activated, just follow instructions below to reset the roll bar1. Raise rear headrest to its highest possition
2. With a screwdriver, remove the plastic cover that is located under the headrest between the roll-bar.
3. Reach down into the opening to locate the metal tab that has locked the spring loaded roll-bar into place.
4. Simultaniously push the tab in (towards the front of the car ) while pushing downward on the top of the exposed roll-bar to compress the springs. Push all the way down until the bar locks into place.
hope this helps please comment and rate thanks

just push the roll bar button in the up position like you raising the roll bar. hold it for about ten seconds or til you hear a click sound. basically your just going to reengage the mechanism again since the roll bar got deployed while driving. If thats not the case then you might have a separate problem but I would start there.

I have 1997 mercedes benz sl500 after changing my battery, my roll bars will not go down. how do I get my roll bar back down?

the soft top module is receiving an illogical switch input. try retracting the top untill all the locks are secure. Make sure your roll bar operates o.k.. also only operate this top with the car running and the windows up. If it still won't work I would suggest having the car scanned for codes. You can try disconnecting the negative cable on the battery and secring the top manually and see if reconnecting neg. will clear the memmory.

The window position is monitered by the softop control module. It sounds like the glass is very dirty and drawing too much amperage during window operation. The soft top is electro hydraulic. The roll bar is operated normally with hydraulics but it is mechanically released in an emergency situation. 1st make sure your windows are clean and the express(one touch operation) is working-the soft top will not function properly if the windows are not synchronized. Next be sure your roll bar works-hold swith in up position to lock roll bar rams in if they have been deployed. next put your top all the way up. untill windows roll up and try it with the engine running and trans in nuetral- if it still does not work mechanically secre rear of top with tool provided in your tool kit the owner's manual will tell you how to do this. good luck

It is normal for the roll bar to rise when top is down. It seems like the rear valance cover is not secured and the soft op does not understand what position it is in. There is a way to manually close top. it is stated in your owners manual. also I would try to close top with button(assuming your vehicle will start and the battery has good voltage) start car and try to operate top down and try pushing on rear cover also make sure the retractable cover in trunk is extended to compress operation switch

I have a 2005 CLK 320. Roll bars deployed on a bump with the top up. Here's how to fix it: There is a reset port about 12 in below each headrest. The port is hard to find, but you can actually glimpse it with good light and/or a flashlight and some head/neck contortion. When facing forward the port is on the left side of each headrest. The port is oval in shape, about 4mm x 8mm, positioned about 10 mm forward of the support post and about 5mm to its left. Essentially, its an oval hole in black sheet metal. Mercedes mentions an allen key tool included with the car, but you can use a very long screwdriver or, preferably, a metal shishkabob barbecue skewer (by far the best) to reset the mechanism. Slide the tool (skewer, screw driver or allen key) straight down along the side of the headreast and then very carefully angle the tip forward and to the left (of car) to go into the port. Again, you can see this if you try. Push down on the spring under the port and hold down while you push down (Hard) on the headrest to its full reset position. Then remove the tool. Voila!

Before the reset, the top would not go down. After the reset, no problemo. Dennis
