I've got a 2000 model conv. that when youturn the lights off the right motor continues to run for a couple of seconds after the door is closed. Also possibly related is occassionally when I turn the lights onthey do not come on unless I flash the brights. Thanks.

 

Sounds like you might be having a gear going out in the motor, You can replace the plastic gear with a bronze one.
Here is a link to the gear repair.

About the light issue you might have 2 probs.

My 02 Z06 did the same thing....with the headlight motor....not sure about the lights not coming on unless you flash the brights....hopefully someone on here has heard of it and knows what to do. I agree with Bill K about the gear going out. I got that exact kit that he gives the link to. It was pretty easy...once you get the light assembly out of the car...just takes some time. My lights sound different know when they go up and down...nice and smooth...and the issue I had that you describe went away. If you have any questions on how to do it, let me know.

 

Some tech writers - one for Vette magazine, for one, is a believer in nylon gears, as opposed to brass or bronze, because the motors are really small, and the heavy gears will wear down the motor (which I imagine is probably more expensive to replace than gears).

 

I never thought of that.....ooops...too late now...I have those in there now I turned them by hand before and after....sure didn't feel any different...but just might not be noticeable by hand....guess we will find out a few years down the road

 

We installed the Bronze gears in our 98 WS6 and have been in there for 2 years now and never had any trouble at all, My motors are almost 10 years old now.

 

i bought a used motor on ebay for $35 and it works great
