The next job is the drivers side headlight that thinks it's a swimming pool. I thought initially it was getting in through the clear cover on top of the light unit, so i fitted a piece of flexible plastic larger than the cover over the top . Is there somewhere specific i should be looking. Many thanks. Anthony.

 

TSBs are your friend.

 

The main area is the water shoot that comes along the wing .make sure its in place .
Next is to push the white plastic cover down by putting a wooden bloc or wedge between it and the body to push it down, You can also put a large bag of desiccant under the plastic lid Main thing is the plastic shoot... Dry it out with a hair dryer
We should meet up we are only 10 miles apart.
