Water leak inside both front floors fixed

Hello all,

Was scouring the internet trying to figure this out as we have been having some downpours in San Diego lately. I decided to verify the sunroof drain hose was not torn or pulled out somehow. Procedure is to pull back the front door seals near the headliner and front sidecovers, remove the sidecovers on the sides of the interior windshield, remove the two screws on the sunvisors and remove the grab handles in the headliner (torx screws). This will give you enough room to verify the black hose.

Sure enough, mine was pulled out on both sides. I suspect both age and heat shrunk the hose length enough to pull out. I did blow thru the hose and could hear some blockage down the tube, but enough huffing and puffing, it cleared itself. I reattached them (driver/pass hoses) and used a ziptie as a clamp, so this wont happen again.

Didn't take any pics, but a straight forward job. We'll see in the next rain if I fixed my issue.

Nice. I'm gonna look at this when I take off my pillars for regluing the fabric.
