windows developing chirp when opening

As the title suggest, my driver front window first developed the chirp maybe a year ago and ive lived with it. Now the passenger front has started as well. It only occurs upon opening and it's instantaneous.

Anybody else experiencing this? If so, is there any point that needs a little lubrication perhaps? I've applied 303 protectant along the seals but it didn't resolve the issue. Maybe it just didn't reach deep enough in the recesses though.

Anyhow, I appreciate all responses.

Thanks

 

okeedokee... no responses so this must not be common. Well I guess I may try to soak a q-tip in the 303 protectant and get into the seal window recess then. Hooray for long weekends.

 

I assume it's coming from a seal (hence the 303 on the seals), rather than from inside the door? My dad's Dodge started having window squeaks, just a little chirp, and now it's this fingernails-on-a-chalk-board, hair-raising shriek the entire time he's rolling the window down (and he won't get his A/C fixed, so this means it's every time he gets in the truck from about March through October). It was hard to pinpoint the sound but it's coming from inside the door. I think if he just pulled the interior door panel off and oiled the motor it would probably fix it.
