To open it, I have to push the button like 10-15 times. Each time I push it opens it like an inch. Getting real annoying. To close it, I can hold the button to close it but I can't just hit it once to auto-close it. Also, when I'm opening it, it tries to open farther than it normally would if it did automatically. It his the sunshade then makes a noise.

Any suggestions to fix it? Thanks.

 

Okay, after messing with it for a bit and not doing anything really special, it started to work a little normally again. I can auto open it now. I can't auto close it. It starts to close then opens back up. If I hold it though, it will close. This happened to my E320 as well. Is there a way to fix this?

 

I'm no expert but look up resetting the unit by holding the switch down for a few seconds after turning the key on. I had to do it after removing the battery. There might be more than that to it but you can look it up in the manual or online.

 

Try pulling fuse #9 (on the rear SAM, in the trunk) to reset the Overhead Control Panel.
