Water in side air vents

Post by Lowbrook » Fri Nov 08, 2019 9:21 am

Hi, I don't know if this is a common problem, I have a 1969 Scimitar SE5. The car has been relegated to live on the drive, prior to me restoring the car to give it a fresh lease of life. Since living out in the elements, I have noticed when it has been raining that when I drive off, the two fresh air vents either side of the car are full of water and slosh out into the the car as I drive off down the road, which is interesting to say the least. Is this a common issue and where and how is the water getting into these vents, so I can rectify the problem when I strip the car? Any suggestions would be welcome. Many thanks in advance, Ian.

I think they’re fed from the plenum on the scuttle below the windscreen, so it sounds like the drain hole is blocked?

Jim's suggestion is good. You can see the drain by looking down into the plenum.

Is the water definitely coming out of the vents themselves? Water can get into the body void surrounding the corrugated hose feeding the vents and leak into the car through the vent surround (only the centre of the vent is connected to the plenum - see pic below). MIght be worth checking the screen seal, especially if the car is parked nose-high.

This picture shows the 2 side vents from the plenum chamber if it helps.
There is an offset hole, not sure if pass or driver, at the bottom of the plenum that drains the water all over the bell housing in front of the heater.
When this gets blocked the water drains through the heater instead and rots the heater away or if you are lucky, that is also blocked it comes out the fresh air vents!
