Water sloshing by passenger feet
« on: July 16, 2019, 18:43:10 »
I washed my car on Sunday and took it to work today (Tuesday).
When I made a turn, a big slosh of water was dislodged from the right side under the AC and dripped down the passenger kick panel.  It wasnt a steady drip but more like a good cup full.  After drying , there was no more water. 

Is there something I should look for on the firewall to see if there is any opening?  Very weird--it happened that last time the car was washed as well.  It never happened before. ????

Regards

Yes, the drain pipes, under the dash inside the car. Run something through to make sure drain hoses are not clogged.
Also check them both to see the that the hoses are not rotted (cracked)

I had the same issue. My car does not have the factory correct antenna, but does have a small rubber seal/grommet that was worn, cracked, not seating properly between the antenna base and the fender.   The few times I did get caught in the rain water kept coming in under the glove box by passenger feet.  Replaced the rubber seal, no water coming in.  I'm not sure what the correct factory antenna mounting is like, but you may want to check.

Steven,
Read the "heater drains" section in the technical manual here.
It is very likely that they are choked with debris in the plenum chamber,a simple  job to clear.

Steven, if yours looks like in Hans picture (second post) which appear to be original based on the clamps, make sure you give them a squeeze.  Mine looked fine until I squeezed the rubber and they fell apart.  Had the same issue as you.  After replacing the drain pipes, no more water.

I removed the fresh air grill and removed the filter.  The entire area was filled with water!
I used a coat hanger and unclogged the 2 drains....worked like a charm! I reached into the engine bay and removed the rubber "Bulb" looking piece.  I ran water through it and cleaned that out as well

Now I know where the water came from!
Cleaned out and moving on!
