Title: water leaking under dash when it rains?
Post by: Metal Man on September 08, 2021, 07:55:58 pm

My Floor board is soaked after a rain. Any ideas where to start? Looks to be coming from behind the air control box behind the glove box. What is need to repair?

A garden hose and a flashlight. Have an assistant spray isolated areas while you observe. Most common leaks come from, failed seam sealer in the cowl and or rust, missing or failed cowl seal, associated grommets etc (points of entry on the firewall), and windshield area leaks. Good luck
