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

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".

Title goes here

If the main fuse box can be provided with a 12 volt supply to the rear solenoid that opens the boot this wil trigger the lock to open . Also this can be provided to any circuit that is through to the battery BUT MUST BE DONE WITH GREAT CARE and protection.

brake switch needs replacement.

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.

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.

think this is a dealer job ,the radio is connected via a big computerised circuit board behind the centre column of the dash .try giving the wires under the front seats a wiggle and make sure their are no coke cans or anything else under seats to damage the connections for the explosive seat belt restraint puller devices

I purchased a MB CLK 320 and set the radio frequency and successfully put the freq in memory, however, the radio blinks tthe freq. Is this normal or do I have to enter another key to stop the radio from blinking?

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.

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.

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
