I have a 1999 CLK 320 and the headrest will not go down. I never hand a manual for it as well. I can hear the clicking by the seloniods when I press the buttons. Can anyone help with this please. I am not thinking it could be a fuse issue. Of course, with out them being down I can not even manually put the top down. I have the top down now only because I took out the back seats and removed the headrest deal to pull the top in the back compartment. Any help would be appreciated.

Thanks.

Have you tried resetting the head rests by pressing the button up for 15-20 seconds until the system resets?

As CLK sugested.. start with the easy fixes first and try the reset of the headrests. Get yourself a manual or search the forum for info. It's loaded with info and will save you many headaches. The top can be operated manualy with the headrests up or down so the removal of them was not necessary. If the headrests were deployed automaticaly they will require a simple reset to get you back in business.

like what the other saids.. rest it and it will go down.
Its most likely from the sensor. My car does it once every 3 months when i hit a bump or pot hole or something.

Does the car have to be on. Thanks for the help. Really appreciate it. Also do you have any more suggestions.

Thanks.

Were else can I obtain info to fix the headrest problem.

Thanks.

no but u have to turn it to the second click . u can do it while driving too.. i reset mine while driving LOL

Do you still have the back seat off?

Take a picture and post it so we can see what's going on.

I will try on my way home tonight. Hope it works.

Thanks.

Yes I still have the seat off. I also had to take it completely down so I can get the top back up again.

Did you ever find a solution to your problem? My top stopped working and the headrest were unresponsive. I tried the reset and my headrest got stuck in the up position. Now when I click the button I hear the clicking noise from the back but nothing happens.

I replaced the relay in the back but still no luck. Also, because the headrests are all of the way up, I cannot manually put my top down

Before I take it to the dealer, can someone please offer any advice that you may have.

Thanks,

Fred

I have the same problem, swapped relays on w208, hear a clicking sound from relay, all fuses good, no hydrolic leak, I'm stumped!

Is the switch flashing fast or slow? Fast would indicate an open micro switch

Does your convertible open top button stay lit up or blinking?

Seems like the switch is blinking slow, windows will roll down, when I unlatch the top, then a slow blink on the switch. I thought I had tried every option available, swapping the fuel relay, have the entire back plate out, as I understand there is not a release on the w208, I hope I dont need a hew Hydro system. I did notice when the issue happened a few months ago, the rollbars went down very slowly, then stopped, smelled something out of the ordinary from the rear, but hydo fluid is intact, is there a motor I can replace to get the rollbars down? I fugured out how to manually operate the top, but the bars are just low enough with enogh nudge I can get the top down and up, pretty hard to see out the the back, I was actually in an accident, for hitting someone in my blind spot, bec the rollbars block the view -1k deductible week before x-mas

The sqitch seems to stay lit up for a moment, then does the slow blink, I am not however getting any red light on the switch that rolls down the roll bar on the dash, just a clicking sound can be heard, even with the swapped fuel relay

Slow movement followed by no movement followed by smell sure sounds like a burnt pump motor to me.

This is an old post, so hopefully I can get some help. My 2000 CLK32 a208 rear headrests are stuck in the up position, too. As you know, the headrests are connected together in this car so I cannot use a tool to lower each one. I have the back seat out and can hear the click when I hit the headrest button but nothing happens. I am also having trouble with the fore/aft button for the drivers font seat, the front window switches do not work, and of course the top and rear headrests. Are these connected together in a circuit? I'm getting ready to take it to a shop. It runs great, but has these issues.

I'm having the same problem plus when I pressed the headrest button yesterday my car stalled, locks stopped working ,interior lights and remote does nothing now

That sounds most like a battery issue. Have you replaced the battery lately?? If you have, then check the voltage across the convertible/head rest pump to see if you might have a short circuit showing less than standard 11-15V.
