2010 G37 Glove box water leak?

[Bahhbeehhaaaa]

Hey guys,

I hear water storing up behind the glove box area, can someone point me to the right direction? Passenger side floor mat is all wet


Thanks!

Have you had anyone try to diagnose where the water is coming from?
Is it just water or is it green like coolant?
Does the water leak when it rains or when you wash your car?
More details will help. Have you had anyone peek up with a flashlight to see where the water is coming from?

Check out the passenger side engine grommet under the hood. They tend to fail on our cars. If that's the case then place some clear silicone sealant around the grommet.

Other common leak locations in our cars are the sunroof drain. You can check the passenger side on out by popping off the a/c vent and flashing a light, which will show the sunroof drain. Also, check out the windshield seals.

I just went three this on my 08 G35S Sedan which is essentially a G37.

I searched Internet forums high and low trying everything I read and everything pointed to the grommet under the windshield.

After weeks and weeks of trying things i finally figured out what it was.

On the firewall, on the inside of the car there is a plastic grommet with a nipple on it that the passenger side sunroof drain connects to. In my situation the grommet lost it's seal against the firewall and was dripping down under the glove box. I ended up making sure it was completely dry and like a ninja, put silicon on my finger while looking threw the vent caked it on and so far so good 2 months later.

There's 2 ways you can try to figure it out. I poured really hot water down the sunroof drain, which caused condensation to form on the windshield from the steam from where it was leaking.

You can also pull the passenger side air vent out of the dash and with a flash light slightly see the nipple, you may able to see the drip while you pour water down the sunroof drain.

I'm not sure how much you have looked into things, but if yours is anything like mine it took me weeks to figure it out. I suggest you pull the passenger side carpet back in the mean time. Under the carpet they have styrofoam as sound deadening and the floor actually has a dip in it and can hold 6L of water.. Mine was full in heavy rain storms.

Hope that helps, and if you have any more questions let me know.

Any luck with your leak? Just a heads up, I just found a leak in my car due to the heavy rain the past few days. It ended up being the air duct under the cowl for the cabin air filter. It seems like the seal underneath it failed. I just applied some clear waterproof caulking all around it.

I worked for nissan before, the G sedans from what i noticed and experienced from my time at nissan is that the drain plug / drain hose that is what causing the leak. They are somewhat tight space to get to but doable. Remove, side pillar and door weatherstrip and visor and lower the headliner abit you should be able to access the drain hose. Drain plug is down the pillar into the firewall, tight but doable.

If anyone ever runs into this message me, it’s a huge headache and may not be the drain behind the vent lol
