Does defrost cause water to leak under the Tahoe?

[4candice]

I have a good amount of water on my garage floor. Appears to be coming from the cylinder behind the glove box. Same area that usually leaks when the A/C is running. Should I be concerned? I used a white paper towel to dap the water, it's clear and odorless, so I'm assuming its water. Help...

Yes it should be draining on the passenger side, when the defroster is running you should here the A/C clutch engage and disengage which means the A/C is running like its supposed to so yes water will drip.
