I use a Canon Vixia HFM301 to record interviews with bands. For a long time, I recorded the interviews without using a microphone, but recently, several videos ended up with a few seconds of loud static here and there that made it impossible to hear what the people were saying. Also, the sound tends to cut out on one channel at times.

You might try a product called Deoxit to clean the contacts on your mic plug and the camera's mic jack. Use it sparingly. I'd just use a light coat on the plug and insert and remove it several times into the jack, giving the plug a little twist as you do. Wipe off the plug, reapply some Deoxit and repeat the procedure 3 or 4 times. A little Deoxit goes a long way and it seems to have almost magical powers for cleaning and lubing electrical contacts.
If the jack itself is damaged you might consider using a stand-alone digital audio recorder. They're not terribly expensive, depending on your requirements, and I think some of them have some built in filtering to reduce background and wind noise. You should be able to mute your videos soundtrack and synchronize your audio only file to your video in your editing software.
