Resticking door lining without removing card

[Toasty]

Hi,

I cleaned my door interiors last year and I was obviously a little too enthusiastic with the spray...and as a result a small "bubble" has appeared on the door lining; I guess the adhesive has been diluted so it doesn't stick any more.

I was wondering if anybody had any clever ideas on how to re-stick the material WITHOUT removing the door card?

I was thinking of buying a syringe and maybe trying to spray a bit of spray mount into the bubble and then pushing it back into place.

Any other ideas would be really appreciated.

Thank you.
