water under the floor mat on driver side, 240dl. source not visible. not wet any where else. help. 89 240 DL. thx./Joe

Had same problem 2 months ago with my 89 240 sedan plus draining to lower area on back passenger drivers side. took carpet up and pulled off shroud under steering wheel . if you look up near firewall there is about a one inch hole that actually leads to area where water drains into cowl vent in front of windshield , if your drains are plugged anywhere the water could overflow and easily get in car. plug hole or holes elsewhere and make sure drains are clear.could be this or something else,full investigation is in order. good luck

Thanks for the info. Do you have any idea how to get at the drains, would that be in the area you described? thx.

if you look along the undersides of both drivers side and passenger side on your vehicle below the doors and what is called the sill, you'll see little holes down there that let the water drain from your cowl vent. I think that there are about 4 0r 5 along the length of the bottom of the sills on both sides ,shove wire or a coat hanger in all holes and see if leaves or other gunk has accumalated in there over the years, highly likely and it was a poor design by volvo I might add not to put a fine mesh screen along that cowl vent so crap couldnt get in there. Look throughly ,youll find them.
