Guys i've noticed in the past few weeks, theres a constant bubbling of what sounds like water behind my glovebox somewhere.You can't here it from the outside, but when you open the passenger side door you can here the bubbling from between the gap in the door and the front left panel.What could this be??
that would be the bubblator wig wom It could also be the AIV system that has water trapped inside it. Do a search on AIV and GURGLING to find all the answers.
If it is the AIV as Chewy suggests... ...then this tech article may help:Removing the Air Induction Valves (AIV's)Or, if you just want to know what an AIV is: The Online Nissan 300ZX (Z32) Service manual
A/C system may be low on gas? > When my other car's aircon system had a leak, there was a bubbling sound coming from the evaporator (behind dash). cheers, Troy
Sorry but AIV 's ? >>-- you should be able to hear them outside more than inside the car. After all they are inside the mudguard. :YD :YD
Not necessarily....... when my passenger side was gurgling I could hear it from outside only if I was concentrating on it. But it was louder from inside the car where you didnt have all the engine noise and noise from "outside" getting in the way. Infact, I only noticed the sound from inside when I was sitting at some traffic lights. Obviously, it was the loudest when I would open the door and jam my head down between the door and dashboard. I hope its his AIV's gurgling, because it is one of the easier things to fix on a zed..Cheers
Hopefully I'll stop these AIV monkey's from gurgling, don't you worry about that. It shits me!It's weird though, it gurgles as soon as I turn the engine on. You'd think it would have to wait a while to warm up or something, and it stop as soon as I turn the engine off..I'll have a look and see what I can doThanks guys
that's because the AIV system is used primarily to reduce emissions on cold startup by adding extra fresh air into the exhaust so you will mainly hear it on startup. For whatever reason the AIV system gets water trapped in there which is supposed to be blown out on deceleration but the reed valves get a bit crappy and doesn't always blow the water out.
