I am guessing that the Integra is the A Class on the tag axle Alko chassis.
If so, then put your hand up behind the rear bumper and feel (or look) where the rear end of the body meets the garage floor. It is not uncommon for damp to strike at this point due to spray being thrown up when driving in rain. I had to have some remedial work done on mine because of this.
It is not cheap, a few hundred pounds (I cannot give an exact price as I had a number of jobs done at the same time (Hab check, awning removal, bumper repair etc). It should be easily rectified if so.
