I had nothing else better to do this morning so I thought i would try and find a slight rattle I had behind my dash. I did try to record the rattle while on the road but to be honest it wasn't very loud... just irritating !! I got to the cause of it but bare in mind that it does sound exagerated with the dash out !!

After stripping the dash down this is what has turned out to be the culprit.

After sticking some edead around the two offending items it appears that I have cured it.

I thought the following ‘How to’ may come in handy for any owners that may be interested in how to get to the back of their clocks to cure similar rattles. Although I set out to just rid myself of this one annoying rattle I took the opportunity to secure other things that I thought had ‘rattle potential’ while I was in there !!

First we have to remove the centre vent. To be honest the removal of the vents is the trickiest part of the whole process.

The vents are held in place with plastic spring type lugs. I use a strong straightened out paper clip to release them. I keep a gentle pulling pressure on one of the vent knob adjusters while releasing the lugs. This slight pressure allows the vent to come out slightly and thus preventing the lug from springing back into its slot.

The pictures show the position that the ‘removal tool’ needs to be in and one of the ‘lugs’ levered out of its location. This method also applies to the side vent. BE VERY CAREFUL THAT THE VENTS DON’T COME APART WHEN YOU REMOVE THEM’. Although this has never happened to me I have read of it happening.

Image


You can see from the pictures that I took my hot glue gun to the vents to prevent this happening should they ever have to come out again and also secured the parts of the vents together which also prevents the two parts from rattling. (When you get them out give them a shake and you will see what I mean).

With the vents out you can see what the lugs are like if you are going to do this for the first time.

Once the vents are out you have access to the EHU which is secured with two torx screws. Unscrew them and lift the unit out a few inches to access the single connector on the back. Press the release tab and pull the connector out of the EHU and move it to a safe location.

Image


The vertical column of switches to the right of the EHU is just clipped in. Put your hand to the upper rear of it and squeeze the prongs towards each other. Push it out of the dash from the top and then lift out of the dash.

Image


Push in the tab on the connector and push the connector lever over it. The connector will come out without any force being used.

Now all the screws that secure the dash trim are visible. Unscrew them being careful not to drop any into unreachable places…this will only give you ‘another’ rattle !!!!

Image


Lift the dash surround away from the dash being careful not to scratch the finish which could lead to premature ‘peeling’… we’ve all read about that…right!!

Now all we need do is remove the four torx screws securing the clocks. Once you’ve done that lift the clocks out and release the electrical connector from the rear. There is just one connector… simple.

Ok now we can go sort that rattle. As you have seen on the video my rattle was between the plastic cable trunking the flat metal plate at the side of it. I used some edead that I had left over from soundproofing my boot and doors ( another ‘how to’ with pictures to be done soon. Well worth the time and effort if you plan on keeping the car and cuts down on road noise. Helps with the bass from the door speakers..blah,blah..I digress)!!

Image


I also found that when I tapped on the top of the plastic cable trunking directly behind the clocks that it had potential to rattle.. so I used tape to secure it.along with the wires that ran in front of it.

Image


Once I had quietened down the rattle I had set out to do I noticed when gently thumping the bottom of the dash that I had another rattle lower down. This was found to be a plastic cover over the top of the footwell down light.

To get to it I had to remove the tunnel side panel which is held by one torx screw which is under a plastic cover. You need to put the seat as far back as you can to get to it. Remove the screw and the panel slides downwards, then backwards and out it will come.

Image


I then unscrewed the cover that is directly above the pedals. This is held with two torx screws.. and the tech 2 socket needs to be removed..this just unscrews and passes through the panel.

Image


The panel will now pull out and drop down… disconnect the wires to the lamp and take the panel out.
You will see a cover over the light. This is just slotted in…
I used my hot glue gun to place four blobs of glue as on the photo.

Image


Now in the words of the famous Haynes manuals…. Installation is the reverse of removal !!

Wouldn't let me post all the pictures... So I'll probably do them in another post later.

Please feel free to PM with any questions and I’ll do my best to assist.

This pic gives you a better idea how to get the column of switches out...

Put your hand in behind and squeeze the prongs together...

Image


Image


EHU out...

I'm sorry I couldn't get it all in the first post...spent ages on it then told me I had too many images .. Grrrrrrrrrrr

Fantastic! I've been wanting to remove the center vent to get it to stop squeaking but was afraid given other's problems with "broken tabs". Your pictures and guidence helps me manage that risk.

I will add that when I pulled the drivers side vent to make it stop squeaking I added small strips of electrical tape to the back of the vent that faces the mating portion of the dash. This completely fixed that problem. Now that I am armed with your photos I plan to do this for the center vent and the vertical column of switches.

Thanks Again!

Thanks for comments. Makes it even more worth while when other people benefit....

Great job Ambi. I know what you mean about little rattles. They drive me nuts:x.
A month ago I came home from a 12 hour shift. I heard a rattle in my doors for a few months at that point, and it drove me crazy. I was fed up with the dealer telling me that they couldn't replicate the problem. So I ended up taking both doors apart, and spent the next 3 hours dynomatting every nook and crany.
In the end, I was really exhausted, but finally happy.:D

BTW, Dynamat hushtape does a very good job of stopping rattles and scweaks between plastics.

Once again. Great job.

Thanks. I have practically finished soundproofing the whole car with edead.. similar I believe to dynomat. I have done boot floor,rear arches,all four doors, and under the bonnet. The Aero is getting to the point of what it should have been out of the factory.
The one thing I have noticed is how little there is in the way of soundproofing and baffleing. The doors have a strip of baffleing on their outer skin that is about 4"x8".. maybe enough to baffle but certainly not going to soundproof anything.
The boot lid doesn't have anything on it at all...neither does the bonnet. Those two areas just act as amplifiers for any suspension and road noise.

Yeaterday was the first time I had a trip with passengers. It's a different car.. no embarrasing creaks and rattles... apart from one that only I could hear.. it's the window in the frame..every now and again..I'm working on that one !!

All in all I am more than pleased with the edead. The car feels more solid and the doors close with a good healthy,solid 'clunk'.

I still have a couple more areas to edead...I feel I may benefit doing under the rear seats, front inner wings, front bumper and the large plastic tray that runs under the front of the car needs some work..it sounds like a big drum when you tap it. I think it's all about the ' sum of many' when talking about the rattles and squeeks from the Saab.

As far as the extra weight is concerned... well, I don't think the 80 SqFt of edead that I have used is that heavy to make any significant difference to the performance..... I read that 1sqft = 0.5lbs so I've added 40lbs.. I can live with that. I should have taken pictures while I did it but got totally engrossed with the job in hand and forgot !!

Great post, I used it today to cure a ratlle in the dash.
Sadly I ruined my two vents in the proces.
The first because I started working on it without seeing this post.;oops:
The second, smaller one, didn't come out because my dealer fixed it in there with glue to cure an old rattle.
I didn't know how he did it at the time, now I know...:evil:
I had to remove the smaller one too because there are 3 more torx screws under there that have to be removed before the dash comes of.
I managed to assemble them again but the air regulating buttons are way to loose now....:cry:
I'm now in the process of finding new ones. At the dealer's, the center one alone costs 191€ which is like 200+ USD...
All tips to assemble them "factory firm" are welcome.
Greetings from Belgium

Thanks! Another quick question, I'm planning on repainting all the trim including the stereo surround and vents. I also wanted to repaint the peeling parts of the climate and stereo controls. It looks like the face plate on these don't come off? That would mean I would have to mask off all the buttons? Thanks in advance!

No............ all goes back together without any need for remarrying unless of course you are fitting new units to your car.
Hey Ambi, good job.
For someone who isn't as enthusiastic to do all the "eDead" work you have done, which areas would you say are the biggest bang for your time/effort if you could only choose one area which was easy to do? Is it the doors? behind the dash?

I've velcro'd all the door seals with a 1.5" ribbon, and noticed it only helped minimally.
Cheers.

Did you end up buying this one compared to edead and dynamat?

Thanks!

So I found this B-quiet stuff online. http://www.b-quiet.com/?googleads
Testimonials seem to provide good reviews, and the price is better than Dynamat.
Anyone have experience with this?

I plan on doing all 4 doors to start. Maybe the trunk as well since 50sq.ft is the best price and I should have some left over.
