07 cl550 waterr in passenger side interior well

Recently it has rained heavily for a few days, but during a sunny day after traveling about 10 miles a cupful or so of water seem to have leaked from the bottom of the glove compartment area onto the floor. I have visually inspected the drain area where the windshield meets the hood and do not see any debris. could this be a heating AC condensation issue or had anyone experience with leaks from the outside?

Clogged sunroof drain?


On a side note, I had this problem last year in my BMW 545. After blowing out all drains and dismantling the dash, I found that someone pushed the lower drain tube back into the fender and put a body cap on the hole. That was fun

Thanks, I'll take a look. Now that you mention it I had a similar issue with a Jaguar Sun Roof.

REMINDER CHECK YOUR DRAINS!
It has rained heavily in SoCal this week and I noticed an inch of water in my passenger floor board!
Searching this board I discovered the A/C fresh air intake box full of water and all 3 engine bay drains full of water also, all clogged with debris.
Cleaned out drains all is well, so far the A/C fan is still working but I know it got wet...damn.

The 3 drains at the front of the car where the bonnet meets the windscreen get blocked and do need clearing (I used a wire coat hanger). They should allow water to escape through a small drainage channel in the wheel arch, however when they get blocked water overflows past the bulkhead and in to the car. I once spent a good hour with my wife's hairdryer removing moisture from the front footwell.
