I was looking at some Hush Panels so I could reply to another members wanted add and found that there was more then 1 type. I thought all 82-92 AC cars used the same pass side hush panel; until I had gathered a few together and compared them. ( non-AC cars used another -different- type....... )

This pic shows 3 different versions of the 82-92 Camaro. These are NOT Firebird hush panels.




As you can see there is 1 style on the far left that has a "step" in the middle of the panel that makes it easy to distinguish from the others. The style in the center has no step in it,.... and the style to the far right has a notch on the center console side. ( shown at the bottom edge of right panel in pic )

My belief is that 1 of these is an 82-89 Coupe/IROC/Z28 style, 1 is an 84-86 Berlinetta style, and the 3rd is the 90-92 RS/Z28 style. Problem is; I don't know which one is for what car. I can't even be SURE that the hush panel in my Berlinetta is still the original........

The only info that I can add;

All 3 types have the same # imprinted in the center above the "RH" stamp on the back side. That number is 14064444.

The 'Solid' and the 'Notch' types also have the # 14048736 on the underside
along the lip on the mounting hole edge...... the 'Step' type doesn't have a number in that spot.

The 'Step' type was the only type that had factory floor courtesy dome lens mounting holes in them. ( I also found 1 of these panels WITHOUT the holes pre-made). None of the 'Solid' or 'Notch' type panels had the floor dome lens holes pre-made.

I'm guessing that the 'Step' version was for Berlinetta, the 'Solid' was for 82-89 Coupe/Z, and the 'Notch' style was for 90-92. Very well could be a basic year-to-year change for all models,...... Can anyone ID the hush panel from their car and post the info to confirm/dispute ??

 

John, I just pulled this one from a 92 RS

 

Figures,... a Pontiac guy is the first to respond

Thanx for posting Steve !

 

Hey John,

My 89 IROC-Z appears to have the notch style hush panel:



Hope this helps...

 

My '87 has the notch style.

 

NoShow - At a minimum the non-factory screws prove it was removed and It's reasonable to assume that yours was replace for a panel in better shape that the original.

I've looked at every E-Bay auction I can find. Most are listed with a generic 82-92 range and most are listed as Camaro & Firebird compatible. ( obviously wrong ) However; almost all of the 'notch' style panels I saw were said to be removed from 90-92 cars ( some were also shown with drivers side to confirm what they were removed from).

I've had more Berlinettas than anything all other Thirdgens. Berlinetta had factory floor courtesy lighting as standard equipment and used a dome cover. I have more "Step" style panels than all the other 2 styles. I've parted fewer 90-92 cars than all others - and have only 2 "notch style hush panels.

My GM parts book ( 82-87 version ) shows the number 14064444 as compatible for all 82-87 AC equipped cars. There is no specification for Berlinetta vs. Coupe style in the parts book, and no good pics for reference.

This site shows that part number for all 82-89 Coupe and Berlinetta too: http://parts.nalleygmc.com/products/.../14064444.html

I Could not find any info about PN 14048736 other than a few auction listings.

I'm still believing in my original assumption :

Step = Berlinetta
Solid = 82-89 Coupe/Z28
Notch = 90-92

 

Holy crap, I didn't even realize there was supposed to be a panel there!! something else to look out for in junkyards I guess lol

 

Just For Comparison,Here's What A Non A/C Panel Looks Like.

 

Makes sense John. Anyone have a 89' period correct hush panel for sale? It's going to bother me not having the right panel under there now lol.

 

Not all cars were equipped with them. More info below:

Looks like early style,... has dome cover holes.

CAREFULL,..... This is still pretty open for debate ! The fact that your current Hush panel kinda' clear of scratches might make it a 'keeper'. These things tend to show a lot of abuse !!

After searching around a bit more I have a bit more to add to this topic. I dug out the original hush panels from my 84 Berlinetta,... both panels were stored together & both have pre-made dome cover mounting holes.



James - I recall that thread about the Hush panels and BOSE. Well; I installed BOSE in my 84 before it was converted to a stick. ( Haven't had the drivers side hush installed since it was converted !) To continue using the Hush panels at the time I had to cut the "fin" from the drivers side hush because it interfered somehow with the BOSE kick panel. On the pass side; the BOSE kick panel covers 1/2 of the hush panels' "grid" and the entire opening for the courtesy lens. ( no alteration needed ) The factory screwed a small plastic socket holder to the kick panel - but I didn't like that because the bulb burnt my BOSE carpet....... So I cut 1 section of "Grid" out and custom installed the bulb socket there for the courtesy.

Point is: I'm almost 99% certain the "Step" version of this Hush was the Berlinetta version. The Heater Box Temp door was cable on "P" cars and electric controlled on "S" cars (Berlinetta), so there might have been more "space" available under the dash in that area to give in Berlinetta cars.

I'm still not convinced about the specifics for the SOLID or NOTCH style panels. After searching around more in recent days I've got equal number of NOTCH & SOLID,... meaning there's no clear trend from my experience. I can say that I've had "mostly' pre 88 cars in my driveway,..... and they always had hush panels. ( Never had a factory BOSE car ! )

P.S. I've got a couple of them if there's nuthin' available in the local Yards.

 

Cool, I'll keep you in mind if I don't find something. I gotta go scrounge up a steering box from something and bench rebuild and adjust to swap for my original one. I can't get the lock "nut" off of the input end to adjust the slop out. I don't feel like taking that one out to rebuild and wife not have her car for a few days to fuss at me either :-/

 

I have a 90 IROC-Z vert with A/C it has the "notch" style.

 

Thanx for the feedback !


I caught up with a buddy over the weekend that had a mostly original 86 IROC last fall. ( Then he let me work on it; so it's not stock anymore ! ) I peaked under his dash and he's got a "notch" style pass hush in his 86.

Doesn't guarantee anything - but worth mentioning !!

 

I was about to post a pic from mine...but then I remembered that most of my interior was pieced together from pristine junkyard pieces...so there's no telling what model my panel came from, haha.

 

Got the factory original out of a 92 RS v6 today and is a notch.

 

Since you've help me with parts in the past , I took a photo of my panel.
I am the original owner of a 84 Berlinetta.

That's AWESOME; Thanx for that feedback !!


Interestingly; So far no one has responded with any info on the "solid" type. After seeing gt4373 non-AC version in an early Z28 - and all the other responses so far - I've got to wonder if I should change my original assumption about these hush panels to this:

Step = Berlinetta
Solid = 82-84 Coupe/Z28
Notch = 85-92 Coupe/Z28

 

Excuse the mess, she's a job in progress. Working on a solution to my speedometer light fading out and came across this, since apparently the lighting module is in here somewhere?? Fiqured I'd shoo

​​​​​​​t a picture of the hush panel in my 84 Berlinetta, hope this helps someone.

 

This is the best picture I have at the moment that shows the approximate location of the Light Module. To remove it you need to remove that hush panel, unscrew the 7mm screw holding the parts to the dash housing, and pull the Light Module / ECM down as a single unit and swing the bottom of them towards the center console so the top will 'clear' the dash housing. Then they can be unplugged / separated as needed.



The Light module will only interact with the Speedometer clusters backlighting and digital readouts. The most common failure of that type is reported as follows: The Speedometer readout works fine until the PARK or HEAD lights are turned on. Then there is no backlighting in the car and the cluster digital readouts go dark. Turn the PARK or HEAD lights off and the digital readouts begin to work again. This is a pretty common Light Module failure and is caused by a burnt DIM circuit inside the Light Module. The DIM circuit is controlled by the small rheostat roller control on the left side of the Blinker Pod ( RED circle in pic below ) so attempt to adjust this control to see if the backlighting is just adjusted so low that it's not lighting-up anything.



I hope this helps !
