LED Gauges & HVAC:
What You May Not Know

*****NOTES*****
  • If you remove the film, light may not shine equally through all parts of the cluster/HVAC controls. click here for reference.
  • 94-00 mustangs have blue film behind the gauges/hvac. 01-04 mustangs have a green film behind the gauges/hvac. (GT's & V6's)
  • Do not attempt to remove film off the back of white face gauges.
Most of you probably know or have seen how to convert your gauges and HVAC (heat, ventilation, air conditioning) to LEDs.
Its a pretty simple procedure of swapping out your bulbs for some white LEDs and your gauges and HVAC will then appear blue.

Here is the how-to on that:
http://sn95forums.com/showthread.php?14693-SN95-LED-Gauge-Cluster

Now what you may not know, is that you can convert your gauges and HVAC to ANY color you'd like with a few more steps.
The reason that your gauges and hvac appear blue is because there is blue film located behind each of the indicators. From the factory, you are supplied with amber bulbs. If you put an amber bulb behind blue film (yellow + blue) the outcome becomes green, as seen in the cluster and hvac from the factory. When swapping in white or blue LED's the bulb diffuses with the film and creates a very ambient blue. However, if you put a red bulb or a green bulb, the light will not shine through the density of the film without losing light. The solution to this is to simply remove the film. Once the film is removed, any color bulb or LED that you get, will shine through without blending or having to go through a film. The original color or the LED/bulb will be the color your gauge cluster and HVAC appears.

Step 1:
Proceed to remove the cluster and HVAC controls from the dashboard.
(
http://sn95forums.com/showthread.php?14693-SN95-LED-Gauge-Cluster) Once everything is removed and you have all component exposed, its time to start the process of removing the film.

Step 2:
This is what you should see. Lets start with the gauge cluster.

Step 3:
Once the gauge cluster is removed (using torx 15 screwdriver) and all connectors are removed, it should look like this:
Go ahead and pull it out and place it somewhere with room for you to work on it.

Step 4: Go ahead and remove all 8 screws holding the glass cover to the the cluster.

Step 5: After all is exposed, go ahead and take multiple pictures of your cluster so you can use it as reference when re-setting the needles.

Step 6:
Go ahead and remove all needles by sticking a fork under them and slowly pulling upwards with firm pressure. They are hard to remove, and don't break easily, so feel free to use more pressure if they are not coming off.

Step 7: Once the needles are off, grab a flathead screwdriver and slowly pry off the black plastic with all the indicators. It should be held down in several spots with some sort of glue/residue. To make things easier, you can use fishing line and place it under the plastic and slowly work you way towards the sides, making sure to remove the cover in all places.

Step 8: After the plastic is remove, go ahead and set the cluster aside.

6479727803_03dc00cfee_b.jpg


Step 8: Now flip over the black plastic parts and go ahead and take a look. You should see blue film covering all the spaces on the indicators.

6479728379_e4dc4e28f3_b.jpg


Step 9: Using a razor, knife, or sharp object, begin to scrape away at the blue film. To make this much easier, you can use sand paper (500-800-1000 grit). Go ahead and remove all the blue film you see. If you are sanding, keep sanding until the back of the cover turns black and there is not blue left. You can be as neat as you want. If you go all over the place with the sanding like i did, do not worry, it will not show once you put it back on.

6479729589_8d69440f9f_b.jpg


Step 10: Finish sanding the rest of the blue film.

6479728975_edc06588ef_b.jpg


Step 11: Once everything is sanded and there is no blue film leftover, go ahead and place the plastic back on the cluster.

Step 12: Before you re-install your arrows, check the pictures you took and place the arrows EXACTLY where they were when you began.

Step 13: Place the LED bulb color of you choice in the cluster. Series 194/168 I believe.

Step 14: Then go ahead and place the cover back on, screw everything back in, and place the gauge cluster back into your car.

Step 15: Turn the car and lights on. Check for any bulbs that are not working or for arrows that were not placed correctly. (some may need re-adjusting).

Done! Now on to the HVAC controls.

PART 2:
HVAC (Heater, Ventilation, Air-Conditioning) Controls:


Step 1:
Once you have easy access to your HVAC controls as shown you are ready to begin.

IMG_0882.jpg


Step 2: Once you've done that, go ahead and remove all the knobs by just pulling them away from the panel. They are pretty easy to remove.

Step 3:
Go Ahead and grab a flat head screwdriver and push down toward the front of the car as shown.
The black clips should come right off. There are 8 of them. 4 on top, 4 on bottom.

Step 4: Once you have that done, and the front of the panel is exposed, go ahead and flip it over.

DSCF4179.jpg


Step 5: Now place your flathead under the blue film and slowly push the screwdriver around the panel while remaining under the film. Make sure to detach all parts of the film from the back of the panel.
After the film is detached and loose, using the flathead, push the film to one side or corner of the panel until you can grab a portion of the film with your fingers.

Step 6: Once you have a hold of the film, slowly remove it by pulling it outwards from the rotating levers.

Step 7: Once all the film is removed, the panel should be crystal clear.

Step 8: Go ahead and place your new LED bulbs in the sockets behind the back part of the HVAC controls.

DSCF4191.jpg


Step 9: Re-assemble the buttons/knobs and slide the front of the controls back into place by placing the 8 black clips back into their original location.

Step 10: Screw the HVAC control panel back into place and put all parts back into their original locations.

Step 11: Enjoy your new and custom lighting!

Someone make this a sticky


Also the one thing IIRC with the film from the factory is that in areas it is thicker than others to help balance the shine so it all comes out at one smooth brightness. With removing the film and running just the LED of whatever color, won't it cause a problem with other areas shining brighter than others (kind of see it in your pictures)

ok this might be a really dumb question so please no smart ass comments, but i took out my cluster gauge awhile back to change out the odometer gear and made the horrible mistake of taking my speedo and tach needles off and now my speedo gauge is off very bad and i got the tach close by ear, now from the picture you took yours off. how did you get it right? now i put it on 0 because it would be common sense, nope apparently it isnt and im off by about 10mph

What i did was turn the car on and let it idle for a few minutes, then removed the arrow and placed it back on 0. The thing with the arrows is that when you put it back into place, there is a certain 'spot' where it will always reset to. Its like a sweet spot for the needle, and once you place the needle in, even if you move it after, it will go back to where you originally placed it. Just play around with it for a bit, and if you need a little help, use a GPS that tells you your speed to calibrate it if you have one.

Theres no real easy way to reset it perfectly unless you get it professionally done i believe, so just place it at 0 when youre not moving and give it a few tests.
Oh & dont push the needle down to far or it will have trouble moving and it will almost seem like its lagging. Happened to me and i was at it for about 2 hours!! :mad:

Yeah, thats true. I'm not exactly sure why ford did that because its in the most random of spots that the film is lighter. Its not perfect, but the color difference is not very noticeable at night.

You can take out the dial indicator part in the dials so light shines through them, it gives them a pretty cool effect too. since you seem to like trying things.


awesome writeup steven :)

also worth mentioning.
the film in 01-04 cars is green, so if you put white LED lights behind them, it still stays green. =/

we mostly don't take into account the white face gauges lol.

do not try scraping the blue off white face gauges, it doesnt work. that was a waste of money lol

hope you took a pic of where your needles were when the car was warmed up and running or you will have a hell of a time getting them back in the correct place. We get people in the audio room all the time that did this but didn't pay attention to them enough and now they are all off. Please correct that in your write up so that you do not feed more people in there wanting to know how to fix them........

It all depends on what cluster you have. Different clusters have different color films. What OP is saying is if you sand off the film then you can put ANY color LED you want to show through. But if you don't follow the OPs instructions and just you have say an OEM GT cluster the film is factory green and a white LED will just make it shine green brighter. Does that make sense?

Yea...my film looks just like the one in his pics so I'm guessing it's blue

If the blue bulbs I get don't light the cluster blue then I'll just sand off the film and stop being lazy lol, I just hate taking off the needles

Did you take yours apart all the way down the film, not just where you swap the lights out? If you're positive your film is blue then you can run a white LED and it will shine through bright blue. Unless you are looking for another color.

Yea I had it broke down completely before (everything) and the film was blue. I'm looking to get them to shine blue. i'll just install some blue bulbs I found at advance and maybe it'll shine blue. my cd player lights up blue so I think the accent will look sick

I just noticeed the circuit board on the bottom left of the cluster in the pic...mine doesnt have that one...only one on the right...Is this that cluster out of a GT or cobra...cause I know the cobras had 2...Maybe the manuals had two also? I can tell the first image of the back of the cluster isn't from a GT because there are 3 resistors and 2 diodes....but it is the Second picture I'm wondering about in reguards to the 2 circuit boards at the bottom
