Car Forum / Volvo Cars / December 2006HELP! Volvo 740 - water on floor!
I have a 1989 Volvo 740 with sunroof. In the last year or so I noticed that if the car is out in a long rain, a pool of water starts to form on the floor of the left-rear (driver-side back seat). It can get to 1/2" of water or so! Anyone know what might cause this? Is there some drainage thing from the sunroof that's not diverting properly? > I have a 1989 Volvo 740 with sunroof. > [quoted text clipped - 4 lines] > Anyone know what might cause this?

Probably the drain hose from the sunroof is plugged up with pine needles or the like. > Probably the drain hose from the sunroof is plugged up with pine > needles or the like. Makes sense. Where does the drainage system run and how do I get to it? > I have a 1989 Volvo 740 with sunroof. > [quoted text clipped - 4 lines] > Anyone know what might cause this?

Block drains can be a problem but less well known is problems with glass sunroofs (as on my 940). The seal goes side on rather than bottom up (like most metal sunroofs), when the rubber gets old it can leak along the inside (rubber-glass join) and it then drips into the slider channel which is not drained and the water makes its way to the sun visors and rear seats. Silicon sealant around the top rubber-glass edge provides a cure for a few years. -- Tony > I have a 1989 Volvo 740 with sunroof. > [quoted text clipped - 4 lines] > Anyone know what might cause this?

Mine got a split in one and water was trickling down right into the crack and dripping into the car.
