My 84 DL wagon leaks rainwater from the extreme right (passenger) corner of the bottom side of the glovebox onto the shelf and soaks the floor/carpet with each rainstorm (leaving a nice musty smell) . I had a cracked windshield replaced, and this did not solve the problem. I removed the cowl grill and looked for a drain that may be plugged but could see no evidence of a drain due to the horizontal fin welded in the duct. Is there a water drain that can be opened up? Will the dash have to be removed to locate it??
