Thought I would work on my headlight door actuator. When I shut off the car, I can hear the air hissing out of the accordion boot. So I took it apart.
Here you can see the hole in the boot.
This is the grommet that seals around the rod. You can see the split across the edge.
Here is a portion the the debris that came out. Maybe 30%
Old grommet, and new grommet.
New boot.
New grommet in place.
All back together. I came across this fix while reading all the Cougar forums, and searching the net for cost effective solution, for the leaking actuator.
I have not tried it yet. but it was worth the $20 that it cost.
Here is the link, to this idea.
