sup guys so i've got a 2000 GMC jimmy i bought it 6 months ago. last month i started noticing water leaking in the passenger floor board, first i thought that it was my AC. after i drove without AC for 2 weeks my floor dried up i went to the car was gave my car an overly needed car wash after i took off i noticed ALOT of water in my floor board. So i'm guessing that the vent below the windshield is clogged up everyone has told me that right below the heater core a plastic hose that drains the AC and that vent. i've look where it's supposed to be and it's nowhere to be found. so does anyone now the exact location, is this hose just very well hid or what thanks in advance.

 

if it has a sunroof your drians may be stopped up!!
