Air Con Rattle

Hi all,

Some posts ago I mentioned that I had a Air Conditioning related rattle in the car. It was not the "leaf" like sound that many have spoken about. This was more of a metallic rattle appearing to come from deep within the driver's side dash or even engine bay.

Took the car in to Peter Davey Toyota in Werribbe (VIC). Took one of their guys for a 10 min drive to demonstrate the rattle. Wouldn't you believe it, it was raining (additional noise to filter past) and the friggin rattle did not make a show. However, I described it a fair bit. After a few hours I got my Presara back. After careful investigation, they found one of the Air Con metal pipes installed very close (hardly any clearance) to the chassis. When Air Con was working hard, the pipe would vibrate ever so slightly (normal), but due to no clearance it would rattle against the body of the car... hence the rattle.

Now its gone. I was very impressed that despite the failed attempt to demonstrate the rattle, they persisted and made an honest effort at finding it... and it worked! Glad that they didn't have to pull out the whole dash as for the other "leaf" rattle others have reported.

In term of "leaf" rattle.

The service dealer said need to change the centre part and need to order the part so I need to coming back next time.

I mentioned whether or not you need to take all the dashboard and he said NO.

Is this true?

because I mentioned to him, if need to take the whole dashboard, no need to fix it because I don't want later will cause something wrong with other area and he said NO.

So, could you please let me know if the dealer fixed your leaf rattle on the centre, did they pull out the whole dashboard or just the centre part only?

Please let me know. Thanks.

Our Presara is also making a leaf rattle noise and upon further investigation i could see one of the fins in the centre dash vent rattling about when the fan speed is set to high. Will have the dealer look at it at the next service.

I didn't have the leaf rattle, I had a different rattle. Read the other posts, other people speak about the leaf rattle. It appears that there are two problems. One is the vent fins. This is an easy fix, does not require dash removal. The other problem has something to do with the back of the dash which is a big job and requires the removal of the entire dash. Dealer will need your car for 2 days to do this. I'd be worried about having this done to my car, but others have reported good results (other than occasional collateral damage like scratched interior parts - but the dealer will fix this too, just stay on their back).

Sorry about the thread mine... just did a search and this is the closest to what I have right now. I am still intermittently coming across a rattle similar to this, but it doesn't seem to actually be as a result of the aircon (from what I can tell, as the rattle is there regardless of the aircon status).

Which aircon pipe was it? I might hunt around the engine bay in mine for a little and see what I find. Was really bad tonight and sounded like I had a bolt stuck in a cylinder =S

I have a rattle coming from behind the centre console. I have a post about 'Broken Intrusion Bar". Turns out that the steel bar that everythng is attched to has a defect. The sound is like a bolt bobbying around in a plastic mug. See attached PDF.

That worries me a little... coz it is that sorta sound i think. Like a small bolt really rapidly jumping around inside a plastic mug...

Hope it's not something that serious!

Will take a look on the weekend if I have time and the weather is decent... :g:

I have finally found the rattle in my engine bay... and I must say it was probably the simplest, most inconspicuous and unexpected thing I would have expected.

The rattle I had, turned out to be the engine earthing wire that is on the drivers side of the engine... This was snagged under the edge of the plastic cover on the engine, and when the cover was moved made a sound similar to a rattle. I re-routed the wire away from the cover, and the sound is now gone! I would never have imagined that if it weren't for me accidentally leaning over the engine to get visibility of a couple of pipes =S

I didnt even notice my air con noise till i turned it up full bore. But when they fixed the dash squeek, they said it had no front vent clips, and it was causing a rattle. Cool now my dash and aircon, and vibration problem is fixed, the car is quiet as.

Very happy.

      Took the dust cover off, heart skipped a beat

      Not sure how many of the old guard are still around… fluids drained, fuel tank cleaned and lines purged, might be time to throw it into gear again.

      Need Advice please

      Suggest that you look at an online catalogue for struts/shock absorbers specifically for the Year and Model specification for your Camry. Easiest way to clean fuel injectors is to use a fuel additive together with decent quality fuel.

      What can cause 2x bolts Missing on break calipers?

      For starters, you are referring to the BRAKE calipers. Missing bolts is highly probable that whoever last worked on the braking system did not properly tighten the bolts to the correct torque specification. Presumably, the brake pads were replaced approximately 6 months ago.

      What can cause 2x bolts Missing on break calipers?

      Hi All, I have sent my car to a local mechanism shop as I heard a big scary clunk noise from the front left wheel part recently. And a huge surprise came back to me is, they told me that my break calipers has two bolts missing. I don’t think it is a common problem caused by daily routine driving. So really need to find out what was happened to that 2 bolts?! How lucky I was for driving nearly half a year without a tight break!! I even have kids on my car… can’t think more now. It’s terrifying 😱

      Engine Immobiliser

      Hi Chris, I would suggest getting a code scan as well mate as it could be something locking out the security starting process, and it may make tracking it down faster for you maybe worth the fee for a mobile mechanic who can do that for you as I doubt it will be a fuse or relay causing it sounds,like something in the security side of the process. I am sure if any others have ideas they will post it, these are just guesses on my part so I hope you get it sorted fast mate KAA

      Fuse boxes info

      I have a Toyota tarago 2002 acr30. I'm trying to find out where I can get the contents list of all the items in the fuse boxes. I think it has 4. I only have one cover in the engine bay fuse box. The other three have no information anywhere. Need to know what the items ( fuses, relays ) are for ?? If anyone can help would be a nights sleep for me..

      Rav4 Nightmare After Dodgy Mechanic

      Hey everyone, hope you're doing well! Unlike me and my Toyota, which is currently in a bit of a mess, haha. I'm reaching out for some help, feeling pretty desperate, to be honest. My 2013 Rav4 2AD-FTV Turbo Diesel is on the verge of being a total loss thanks to a dodgy mechanic who really messed things up. My car's was pristine, but then it blew the head gasket. I acted quickly, called up a mechanic recommended by a friend, and he towed my car away promising to assess the damage. He later reported that the engine was still in great shape but needed the head gasket reshaped to fix the issue. Weeks turned into months, and despite numerous promises and missed deadlines, my car remained in the shop. The mechanic stopped answering my calls or messages, and when I finally tracked down my car, it was sitting outside another workshop, unable to start. Cut to now, after seeking help from a reputable diesel specialist, they've replaced seals, checked compression, swapped injectors, and pretty much everything possible. But my car still struggles to idle, and they suspect the previous mechanic may have messed up something electronic or electrical. I'm at my wit's end. No auto electrician seems willing to touch it, fearing it's a money pit with no guarantee of success. It's incredibly frustrating, especially considering I may lose the car. Any advice or suggestions would be greatly appreciated. Thanks in advance!

      Door seals - causing internal leak

      Hi experts need some help. I have a 2004 Sahara 100series. With all this rain we are having my car has started leaking. It was my father in laws car. It’s leaking water down the pillar trim where the handle is inside front seats onto the dash, down the side of airbag and glovebox and dripping from corner foot area where dash ends and onto the floor. I can see the seal on the roof above the door has a gap in it. Could this be it? 1Q. Who would I get to look at this? 2Q. Anyone had this issue before? 3Q. Where do I begin. Thanks in advance, Sarah IMG_3589.mov
