Water leak into cab.

Hi folks. My 95 YJ has developed a water leak into the cab. It only shows up on the passenger side footwell. I initially thought it was coolant from the heater core but it doesn't look or smell like coolant. I'm thinking it might be from the cowl vent. If the drain tube is blocked will that cause water to come into the cab on the passenger side?

Could be. That would make sense if you are sure it's not coolant. Regardless, you probably are looking at removing the duct work and opening it up

The drain tube is out by the firewall and easy to access from the engine bay. The bottom of it is a flat slit type opening to deter rodents and such from being able to climb up into it. Squeeze it to make it round and see if there is debris in it. To water test it, pour water into the cowl vent only. The rubber seal under the windshield frame can be a leak. The body seam a few inches below that can be the leak. The windshield can be the leak and so can the top and front corners of the doors just to name a few.

If you cannot fix it with a hammer then it has to be an electrical problem.

There's a thread on testing different spots for leaks in the Frequently Asked Questions.
