How-To: 300M Mirrors on Neon

Gnuserup · Post by **Gnuserup** » Sat Oct 16, 2010 5:02 am

Belonging to the discussion at this Thread I met a 300M buddy today to compare if the mirrors would be interchangeable.

They won´t fit directly but it should be possible to change the mounting and plug. The rest seems to be similar.

300M-Mirrors electrical heated, e-adjustable with side-turnlights original

300M-Mirror on Neon door - the mounting is to small, has a different form and the 300M-Mirrors seem to be always painted

The housing and mirror seems to be the same.
Next time I will meet him again and we will try to cross the Neon and 300M Mirrors, because he likes to get the electric folding function on his 300M (which is available on uk-Neons), I like to get the turn signals on my Neon and he told, he succesfully disassembled the 300M Mirror totally a few months ago.

Of course you would need electric folding neon mirrors to even begin.

Those aren't the easiest/cheapest things to get here in the States.

But thanks for something else to dream about.

I have the Concorde (LH) seats tho.

I have them already here for two or three years now but not managed to get them on my neon

The 300M Mirrors including turn light seem to be more rare than them.

I will keep this thread on after working with this buddy on the mirrors

Yep, they are always painted. Well, with the naked eye, I had always thought that these two types of mirrors would be interchangeable but now I see that there is a little more to a switch than just a parts swap. I hope that you are successful as the 300M mirrors would really jazz up the Neon's appearence.

Well this isnn't news to me, it's pretty obvious the shape of the mount is different. However, like you said and I thought, the mirror itself APPEARS to be the same shape. I wanted to swap housings and bases. There is a How-To on LHForums that discusses removing the mirror from the base to replace the signal lense with a Klearz unit. I don't believe an electric folding mirror would be needed. Just a regular folding mirror. AFAIK they aren't power folding (in the US anyway) they just had an option for "memory" on the drivers side. But that's for the glass itself.

Great - thanks for the link.

The power folding mirrors are no must for trying to interchange 300M and Neon mirrors but by the way very helpful to take a look if the 300M mount would be useable for that feature.
Further that 300M memory-function could be interesting for the neon, too.
The 300M buddy told me that he made this function available on his. Should work like turning the mirrorplate down for getting the car parked right and goes back into the primary position if I understood him right.

You may need the RKE module, (I think) for the memory, as I believe that is where it is stored for seat positions. I could have got the seats with the memory option, but it would have done me no good without the RKE from a higher end car. My car does not have RKE anyways.

That's interesting about the memory... Personally I don't want it and can care less, but I know for the LH it's a direct swap into cars that didn't have it. The harness is different though. A 7 pin vs the standard 3 pin.

I never took the bright mouldings on the 300M into account until the OP posted the side-by-side pics. Would there be a way to black out the mouldings and trim them to fit the openings on Neons?

sidepipe87 · Post by **sidepipe87** » Sun Oct 17, 2010 12:15 pm

They're connected to the car, and it would still be the wrong shape/size. If the OP can verify that the mirror housing itself is the same for both the 300M and the neon (dimensions) It SHOULD follow that the mirrors can swap bases to make it work. It's a very delicate procedure from what I've read, but unless I can find a set of 300MS mirrors decently priced I may never get to toy with my theory

Your theory? I thought that it was mine!

Great minds think alike- I've been suggesting for years that someone look into trying this swap.

Lucky as I sometimes be, I unwitting bought a 300M Mirror about 2 years ago. It was declared as a defective mirror out of a Neon

so I bought it, because I wanted to try out how to disassemble the mirrorplate. After I had done this it got back into the box and I never cared about it anymore - until yesterday.

Funny is, that I got this mirror with me to compare it with the 300M. Not surprisingly that it had been fitting 100 %

Back home I thought about it once more and hold this mirror onto my 5th door and recognized that it´s not a neon-mirror, but a 300M.

Good thing is, that I already owe a cheap 300M mirror. Next week I will get a defective (really) Neon mirror and then they will be crossed

Got a damaged Neon mirror today and tried.
Found out that the Mirrorplates are the same, even the housing and the mounting inside it, the servo and plug are different, the mounting is different.

So you will be able to use the hole housing and mirrorplate from an 300M

Take away this part (open tongs on the right side and lift there carefully)

Unscrew these three with Torx 10

The inner mounting is fixed by three braised plastikparts, cut away the "ring" and you could take it simply out.
So you can think about installing an aftermarket LED-Turnsignallight at the housing

You, sir just proved what I had always thought. Now can you assemble one so we can see it on the neon???

Midnight_Rider · Post by **Midnight_Rider** » Sun Oct 24, 2010 1:39 pm

Yes, let's see one put together now!

Gnuserup · Post by **Gnuserup** » Sun Oct 24, 2010 2:49 pm

Unfortunatelly both mirrors were damaged before disassembling.
You can see on the pictures that on both mirrormountings the pins are damaged. Seems to be the regular damage on that kind of mirrors.
So I got no working sample, but just to take a look...:

Neon mounting, 300M housing

Ohh ok, so you got a broken 300M non-signal mirror. I see now.

Gnuserup · Post by **Gnuserup** » Sun Feb 13, 2011 2:37 pm

Little update - I bought an inside- rearviewmirror with autodim out of an 300M. The socket is comparable so you can directly install that mirror onto the neon. Only the plug is different, so you better try to get a mirror including that different plug...

2005.Neon.SXT · Post by **2005.Neon.SXT** » Wed Feb 16, 2011 1:27 pm

Or you can get a Buick Park Avenue's rearview with Auto-Dim and a Compass. It's got the same plug as the Neon, just replace the wires behind the plug and you're done

How's the 300M Mirrors comin along?

Gnuserup · Post by **Gnuserup** » Wed Feb 16, 2011 1:57 pm

Great - good to know

I only tried to put the 300M-mirror on the mirror but had not left it as the plugthing has to be fixed before. It looks nearly the same as yours in your picture.

I know this is a very old thread but this is intresting has anyone actually done this mod i would like to see how these mirrors look on a neon thanks

sidepipe87 · Post by **sidepipe87** » Mon Nov 12, 2012 12:43 pm

I did it. Check my progress log. Posted a few videos
