I just got a LHD '78 Karmann Cabrio / 1303S and the front floorpans were waterlogged....like it had been sitting in a pond! I was trying to figure where the water got in and a possibility is the bonnet/hood vent, it's been taped over and the footwell front corners are rusted out plus both heater channels have also rotted out and feel damp at the front end......Anyone know how the water is meant to drain away from the vent?

Could a simple tubing/pipe problem be responsible for rotting out the front end?

I don't think that the fresh air vent is the culprit..

although I don't know why so many people cover them over etc...

check the bottom corners of the windscreen.. as there are drainage holes under there, in case water does find its way under the rubber...

If water drips [or flows] thru these drain holes, it is supposed to go down just inside the body behind the door hinges....

Maybe it could find its way onto the floor...

 

Back to the air vent...

It should have a pipe coming from the bottom of the plastic housing and going to a hole in the body, for the water to exit...

If it was possible for water to get into the housing , and no drain pipe...

I suppose the water may end up on the floor...

 

I hope this helps...

Thanks...I'll check those areas before the welding starts, it seems to point in that direction but maybe.....the previous owner just left the roof half open in a storm and never took up the carpets or just parked the car nose down in a lake!

I need a manual for this model, does such a thing exist?

Best place to buy a manual or 2 is at amazon.com...

I have 12 different Operator/Owner/workshop Manuals for My Beetle..

You can buy used books at amazon too...

very inexpensive compared with Australian manual prices..

 

If You have no luck there, try ebay....

 

best of Luck

I got this message from a previous owner about the water problem.....If anyone has any ideas..........????????

"I taped over the airvent as I thought that was the cause but it made no difference. It did seem to get worse after I'd had the sill strengtheners replaced; whether drainholes had been blocked off somehow? It was odd because after heavy rain I could get in and the floors would be bone dry but as soon as I drove off water would come pouring out from somewhere. When the guy came to collect it, as he was loading it and the front end tipped up a good 2 pints of water poured out near the back. It obviously collected somewhere but I could never pinpoint where"

It looks like You have a bad problem there.....

The water is collecting somewhere but doesn't wet the floor until the car is moved.....

You could pour some water down the front vent to make sure its exiting under the car... as it should....

Then trying to find where the water accumulates....

When the car is washed.... does any water go under the windscreen rubber... as the holes under there are drain holes....  although bad ones in My opinion....  and draining into something that has been welded up and holds water... while the car is still....

Trying to find this could take some time and could test Your sanity....

 

Best of Luck
