Roll bar on clk 320 cabrio

My roll bar deployed automatically when I went through an extremely bumpy intersection and now it will not go down. I followed the instructions in the manual nut it is like there is "no one home' in the motor that operates it. Is there a fuse for the rollbar motor? If so where? I have checked all three fuse boxes and it is not listed on any of them. HELP!

    I have a 2000 CLK 320 Cab. The top will not deploy, and the rollbar is stuck in the up position, which I believe is the source of the problem with the top. Is there a way to manually lower the rollbar? Initially, I was dealing with the top not deploying, and in the process, I attempted to raise and lower the rollbar via the rollbar switch. I hear some sharp noises, which are described in the manual as "locks" which are normal noises. However, afterward I could not lower the rollbar. Up to now the top has operated as expected in the 16 months I've owned the car. Any suggestions?

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

This happened to me recently, but i can't remember exactly how i overcame it. i think i lowered the windows and released the front roof catch, then lower the head rests using the switch.

I have 2004 CLK 320. The top went down OK, then a few days later it does not close. Any suggestions? Thnaks

this may be a broken track or if it doesnt move at all then it may be the motor or the switch is bad, try pushing the switch hard and hold while you wiggle the switch, i would check the fuses to make sure there are no bad fuses.

My roll bars (back seat head rests) are stuck in the UP position and I can't close the top while they are up. How do I get them down mechanically, the guide shows plenty of info for the top but nothing...

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.

Top will not close clk 430 mercedes benz

did you recently have a dead battery? Either way try to resynchronize your windows (i'm not sure if you meant front window or rear quarter window). If you hold the window switch in the up position(car running and door closed) untill window reaches the top and continue to hold for 10 seconds the window will reprogram itself. try both front windows. This system is complicated and is best diagnosed via s.d.s. diagnostic machine. I will give you a couple of other possible easy remedies. If your vehicle is equiped with a ski window in the rear trunk panal the door must be shut, also your cargo cover must be shut and plastic lid secured. There are numerous micro switches that input to your soft top control unit-any one could cause the top to be inop. Check to make sure the switch on the cargo cover( retractable cover in trunk) is secured to it's housing, they do periodically fall off. Also if your roll bar ( rear head rests ) has been mechanically deployed You must hold the switch in the up position untill the rams lock back into the roll bar-does the roll bar operate? Always operate top with vehicle running because they are very voltage dependent. Your owners manual will explain how to manually raise top and some simple operation and repair remedies. If you are knowledgable about automotive electrical systems you can disconnect both leads from the battery and touch them together to drain the capacitors and it may reset the module( do not attempt if you are not knowledgable with automotive electricity because there are many things that can go wrong. hopefully I have been helpful.

ROLL bar malfuntion. Roll bars will not go down. Is there a reset button?

This system is designed to release the roll bar from the actuating rams due to input from the axle(suspension travel) sensors in the rear of your vehicle. More than likely your roll bar system released the bar and it sprung upwards. You have to hold the roll bar switch in the up position until the rams travel up and lock back into the bar. Once they lock back in the system will be operational again.

Clk top will not go back up seems dead..all fuses checked

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
