Help: Water on the Driver's Floor!

[EWJ]

Hi- Just noticed yesterday the carpet and floormat on only the driver's side of my E39 is wet. It is water, not antifreeze. Also, I've been seeing water drip from the driver's side rocker panel. I've been using the A/C (it's on all the time): could the drain for the a/c sysytem be clogged? Where is the drain tube under the car?

Thanks in advance for the help!!!!

ac drains are above the trans, also check vapor barrier behind the door panal it must be water tight or it will leak

Thanks Geneo for the reply!

Found the problem: the drain in the left fenderwell, where the master cylinder is, was plugged up. Water was up to the bottom of the master cylinder and leaking into the interior where the brake booster bolts to the firewall!

Cleaned it all out and all's well!
