Still trying to find my water leak... I'm starting to think its coming from behind the brake booster? Is that possible? Thanks

 

Rain or trail water right? More likely at the base of the windshield - unless you have self-installed wires punched through the rubber boots in the firewall into the passenger compartment. Apply a thin bead of clear silicone sealer at the driver's side lower corner of the windshield, maybe even squeeze it into the hollow under the windshield gasket, and extend it across the bottom for about 12 inches (more or less). Wait for it to cure - won't take too long - then test with limited amounts of water from something like a watering can or low pressure garden hose.
