Mk 1 Water leaks on passenger side floor

[Garbon]

Does anyone have a solution on how to fix a water leak on the passenger side? It seems to come down from above the glovebox/ air vent pipe area and finds its way onto the cardboard tray under the glovebox and finally onto the floor..

Not sure if it is from the screen or the spae/ area under the rain tray when water sits there depending on how much rain you get

Thanks

Its not your heat core is it??

Either the heater core or the window seal I would say.

In my '93 Mk1 I have two drain holes in the rain tray. (Left and right side - where the bonnet hinges are located). Both have a rubber funnel attached. From time to time these need cleaning out, leaves and dirt block this drain point, water will then overflow into the heater fresh air intake, and then the footwell.

Hopefully it's this easy to repair.

I would look at:
- grommet where antenna cable goes into wheel well;
- grommets where wiring harness goes into engine bay;
- windscreen seal
- maybe heater hose grommet and heater core

Add to that list the brake-line entry. The line is directly under the rain-tray drain - brilliant design (NOT)

Lucky its Friday tomorrow, you will have a whole weekend to find out ahhaa

Any sign of rust bubbles around the outside of the windscreen seal ??? good indicator that the metal under the seal is perforated, this allows bucketloads of water into the car, usually onto the fuse / relay plate making electrical problems a real issue to boot. You can usually see rusty water marks above the fuse plate where the water has been running in.. ( torch required..)

[dub be good to me]

I've been working on a passenger side water leak in the same area. So far I've ruled out:
-Arial hole (re-sealed)
-Windscreen
-underbonnet drain plug (as previously mentioned)
-badly bogged repairs (fixed)

Upon further investigation I've found that if water is sprayed up into the very top corner of the guard (e.g. water flicked up from moving wheels in wet) it POURS into the car from under dash, appearing to come from high up (like windscreen corner or something). I'm planning to take the guard off to block up this hole, not sure if this is bad design, decay from rust or poor repairs.

I'll keep you posted if I fix it..

Good luck!

there is the first place to go in a mk1, rust wise, and completely invisible, as you say, from the outside or general inspection...

moisure held in the a-pillars that eventually rusts the outer bottom of the a-pillar out also rusts out that lower bit first... then, water can get into the lower a-pillar section (along the door hinge part) where it can then enter the cabin...

You can see where the guard fits up against the body at the base of the A pillar in this pic, The exterior paint treatment of the bodyshell is very poor along here as well allowing trapped moisture and dirt to effectively sit and rot the sheetmetal out .



Using the wheel arch liners is a great way to reduce the amount of crud that gets thrown up there, The cabrio had almost no rot there at all, only a small amount of light surface rust .

Thanks for your message, it only leaks when it rains for a while, a light shower and no problems. Heater core should be ok

Hi Michael

I always check to make sure the rain tray is free from debris so the water can get away

[Garbon]

I would look at:
- grommet where antenna cable goes into wheel well;
- grommets where wiring harness goes into engine bay;
- windscreen seal
- maybe heater hose grommet and heater core

Hi

- I don't have an antenna yet
- Still has original windscreen and seal - could be this as the glovebax gets wet a bit also and seee drips coming from the air hose behind the glovebox

I'll check the grommets where the wiring harness goes into the engine bay

Thanks

Sounds exactly the same as mine.

Water comes in here


It runs from there down this hole


down here


And then onto the passenger floor

It drips on to the glove box and the vent hose like you said so looks like its your seal too. Im going to try and seal mine tomorrow
