To remove the headlight unit is done by raising the hood and there are two screws on the top of the headlight, remove them. Under the headlight unit is a tab you use a screw driver to release and the unit is lose to remove. It is a tight to side out, removing the grill helps a little.
In my previous query I wanted to know how to remove the Marker (?) or Turn Signal light. My 1999 SLK has a 2 part headlight turn signal light cluster. I have been told that I have to remove the turn signal cluster first and then there are 3 bolts that secure the headlight unit.
I repeat my question: how do I remove the turn signal light unit???
The turn signal lights slides into the main headlight unit. There is just a tab that holds it in. If you look behind the headlight where turn signal is you'll see it. You press on the tab than push. Than it slides right out. Once it is out you'll see the third screw holding in the main housing.
Thanks for the tips. This morning I pushed the magic spot on the turn signal lamp assembly, removed it, then found the 3 bolts holding the headlight assembly and removed them. After a bit of wiggling I had the headlight assembly out, pulled the clips and found the gummy seal had deteriorated in several places.
No hope of buying a replacement, so I used the best available substitute--clear silicone RTV. Put the unit back in place.
Elapsed time: less than 1 hour. Later I tried the water test--No leaks. Problem solved. Let the next owner figure out how to get the RTV seal broken.
