Hi,
I have a 2000 monte carlo.
Today after coming out of the car wash I noticed a good amount of water leaking from under the passenger side. Seemed like it was from the firewall. Any ideas where this could be coming from? I've never had this issue before

Thanks

 

Its leaking from the cowel threw the cabin air filter

Thanks...gonna head to the dealership now to order or see if they have the part in stock

 

Also check your A/C drain - sometimes it gets crap up inside it. I had it coming from under the dash as well and it wasn't from a leak in the cowl - cleaned out the A/C drain and it fixed it right up. Peel back your carpets and change the padding underneath if it got soaked bad (let the carpets dry good, too) - mine went on for a week before I got it to stop (thinking it was the cowl first, too) and needless to say - it was drenched before I finally fixed it.

They will say it doesn't fit, just buy it anyway

 

The kids at the dealer was cool. He seemed aware of this. They didn't have the part in stock so he ordered it for me and will be coming tomorrow morning. I also asked for a new cabin filter since I was there and he was nice enough to tell me not buy it from the dearlership

 

Yeah it's like $35 from them, and $12ish at autozone
