Ford Focus | Many Water Leaks Video

As James says, this car had been driving the customer 'potty' and he had already had a go at fixing some of the leaks and had previously stripped out the interior and had the carpet out.

The first issue we found was a blocked sunroof drain on the driver's side. The passenger side was clear, so if the cassette filled up to a point where the water travelled across, it wouldn't overflow completely, which is a situation which can happen. However, we suspect that enough water would be sitting in that cassette that it would slop over the edges when accelerating, braking or going around corners, it would then run down into the cabin.

We then moved on to the boot, where we found that the rear air vents were leaking.
There is also a hole, which Fords waterproofs by blanking off with a piece of paper tape. Yes, you did read that right. This paper tape, a bit like masking tape, will eventually come off, allowing water to flow through from the back bumper.

At this point, we assumed we had found all the leaks that were causing the boot to fill with water, and we put the car back together. However, when we tested it, more water appeared. It is possible for the Ford Focus to leak around the rear lights, and for the seams around the door hinges to leak. Testing showed leaks on the hinges, and we resealed the lights just to be sure.

Solution: We unblocked the drain using a drain cleaner, and then tested them again to make sure they weren't leaking from any splits or broken connectors.
The rear air vents were replaced, and we sealed up the hole with a new grommet. We then also sealed in the rear lights and cleaned up those seams around the boot hinges, and neatly pushed a waterproof sealant into them.

After doing repair work on leaky cars, we test the repair, and we offer a three-year guarantee on all work we carry out.
