Symptoms
Wet carpets, a 'wet dog' smell and rust starting under the front mats.
The fix, step by step
- Work through Delica.ca's complete leak guide, worst offender first.
- Remove the front quarter panels above the headlamps, dig out the cracked seam sealer, paint and reseal: that fixed about 80% of one owner's leaks.
- Then check the windscreen seal and the rust-prone screen flange, the antenna base, the roof-gutter seams (reseal with an adhesive seam sealer after removing the trim), the washer-jet stalks and the wiper spindles.
- If the floor still gets wet, look underneath: another owner found the floor pan and a seat-mount bolt rusted through.
