Default C5 Fuel Door won't close

Went to get gas today. Went to close the fuel door and it will not stay shut. I guess the little plunger on the side is sticking or something. When I took off down the road with the fuel door open, I reached out and tried to close again and it worked.

Anybody have this problem? Know what causes it? How it can be fixed?

Thanks for your time.

Default I had the same problem

I had the problem a few months ago. It turned out that the spring in the pin that locks the gas door rusted away and wouldn't pop back to lock the gas door. I did a search on this forum (Great Forum ) and found great procedures with pics to replace it. If you're a do-it-yourself kind of person it won't take longer than an afternoon to replace the spring. Good luck, hope this helps you.

WD-40 to the rescue.....
With the little red tube on so you can focus and direct the spray... spray around the pin then manualy push it in and let it spring back a few times.....
did the trick for me.... 1+ years later and no issues...

Default Did that

I did the WD40 fix for a few months, but it didn't stop my spring from withering (rusting) away.

Thanks Yellow. What did you search on to find the procedures? I am not having much luck....

The car has seen rain twice in it's life and has 12k miles on it. Should I still think the spring is rusted? That would be a drag....

Thanks for your time!

Default Try this

Here you go, this is what I used to replace my spring in the fuel door lock pin. One of the best write-ups I've ever used to fix my C5.

Someone should get these instructions to the moderators so that it can be posted on this forum.

Good luck .

Might be worth taking time to find a stainless steel spring while you are in there so it will not rust again.

I am having this same problem and appreciate the help. I found this during a search on the site. I love this place! I will try the WD40 and then most likely replace with a stainless steel spring.

Regards.

you might want to cheek the release button thats used to open the fuel door because a while back mine got stuck on the open position and would not let the fuel door latch engage.
