Howdy folks, I am calling on the brains trust here to help me with a baffling problem I've encountered.

My 1998 HZJ 105 Landcruiser diesel auto is making a random 'WHOOOOOP!' noise from behind the dash on the passenger's side (I kid you not).

It is hard to describe a noise in words, but the best I can do is it sounds like an electrically generated, ascending, 'owl' type of sound. It is not very loud, but still quite audible to everyone in the vehicle.

It happens infrequently at seemingly random intervals, but it is beginning to do my head in. Even my 2 year old daughter is starting to mimic it now.

I have pulled out the glove box, kick panels and centre console but am no closer to finding the culprit. I have been looking for an aftermarket warning buzzer or something similar but with no success. I've also thought about a vacuum hose for the AC controls but have no idea if they are actuated in this manner in a Cruiser. The only other think I thought to look for was an owl's nest.

Accessories I have fitted in the area are an ARB turbo timer, a GME TX4400 UHF, a Belkin iPod cradle and an aftermarket cruise control.

Somebody help me please!

I had a similar in Darkie, ended up disappearing after I greased the drive shafts. I thought it was comming from inside the cabin as well.


Cheers Kev

Hi. I had a speedo cable in a Triton making a similar noise recently. The cable ran across the firewall and down under the passenger side floor and like your's, the noise was intermittant. Not sure whether you have a cable or electronic speedo but it may help. Regards,Bob.

G'day V8Diesel,
As some others have said it may pay to look further a field, a couple of weeks ago i was driving along and a thumping noise started to happen intermittently, firstly i thought it was coming from the interior, maybe something moving about in the glove box or the dash.When i pulled over it stopped and everything seemed to be in place.When i got going it started again , pulled up again looked under the bonnet, still nothing.Finally i noticed the piece of rubber between the front passenger wheel and the coil spring had came adrift and was hanging down touching the tyre,must have been flicking up hitting the inside if the mudguard.whipped it off ,to put it back on properly later and no more noise.
Good luck finding your mystery noise.
Cheers John.

I had a similar sound in a 80 series, and im positive it ended up being the clutch master cylinder. Thats if i remember correctly, it sounded like it was the stereo or a toy but a mechanic mate pointed it straight out. It was the master cylinder playing up somehow, fluid would rise and then fall under a little pressure, hence the whoooooping noise. Seemed to happen after the gear change too, not during it.

When the 105 cruisers were first released in 1998 the early ones made what toyota described as a trumpeting noise (sounded like a fart) from the airconditioner tx valve that lives in the area where you are hearing the noise from

Does the noise still happen with the a/c turned off ??
