assemblies that use the 9004 halogen bulb.
Cloudy
Headlights
Have your headlight lenses turned yellow & cloudy? |
Mustangs
Plastic Headlights will cloud up with age. An inexpensive solution (other
than buying a new headlight assembly for over $100) is to polish the plastic
just like you would to oxidized paint
|
CAUTION
!
Do not use harsh rubbing compounds or abrasives on the plastic lenses, they will only scratch the plastic & make it worse. |
I
came up with a fix for the severely clouded and yellowed headlight lenses
on my '91 GT, while waxing my boat. Everyone I spoke with said that I'd
need to replace
the headlight assemblies to fix the problem. |
I
have also heard that using Mother's (or any good brand) Plastic
Polish will work ...Spark Plug
INSIDE
? ? ?
|
It may be possible that the plastic lens is cloudy
due to film on the inside of the plastic headlight. Some are skeptical
but if I followed their advice I would of polished through the lens &
through the engine block. That's why I suggest to look inside as well
if you can't clear it up from the outside... here's what happened to me
& might help you...
|
I removed the headlight assembly to caulk the seams, to stop it from turning into a fish tank & blowing out halogen bulbs. First I rinsed it out with water to get the broken bulb pieces out. Then I noticed that a green fungus had grown inside it on the edges. I filled the headlight with bleach & water & let sit for 15 minutes. After rinsing, the headlight was clear. Apparently the yellow-green stuff on the lens was on the inside. As the lens filled with rain water or condensation, a fungus grew & covered the inside with a film that clouded the light. |

Blowing
out Halogen Bulbs?
|
If you are getting water & condensation in your plastic headlight assembly & most likely blowing lots of halogen bulbs, it's time to reseal it. Removal of the assembly is not too hard. You must remove the outermost orange side-marker & loosen the inner one. There are 2 nuts on each side-marker to remove. The headlight has 3. You may have to go under the car & reach up to the nuts to get at some. Be careful not to damage the radiator. Once
you have the headlight out carefully pry off the metal bracket that holds
the hard black rubber (it's a cosmetic piece only) to the lens. Then clean
the assembly out with water. This should also show you where it's leaking
from. Put the metal & rubber bracket back on & install headlight "inside" of the side-markers. Look at the headlight you didn't touch, notice how the rubber is sandwiched between the side-markers. |
Blinking
Lights

This problem affects '87-'93 Mustangs GT's & Thunderbirds.

These
cars were built with a week wiring system to power both headlights &
the fog lights. |
Turn
Signal & Highbeam switch info
|
Due to finding that others suffer from the below problem in 87-93 mustangs
& Thunderbirds
I wrote this to help others who might need it... Ever drive around with the headlights & fog lights on and smell burning plastic? It seems that the plastic headlight wire harness plug that goes into the turn signal switch gets hot & burns out, or something else out. Usually affected by the "normal" fog light blinking due to inadequate wire & relay. |
I smelled burning plastic & shut off my fog lights. The smell stopped. I filled my high beams on only to break the insides of the highbeam switch. While the harness melted it must of heated an internal switch part which made it weak, & broke internally when I used it. Problem: Solution: Not sure what a new switch goes for but you can pick one from a junk yard for around $45 .

HALOGEN
BULB HANDLING
You do know not to touch the glass of the halogen bulb right? Since they burn much hotter than regular bulbs, oil & dirt from your hands will heat on the glass & break it. Handle the bulbs only from its plastic base. |
1987-1993
Mustangs use # 9004 Halogen Bulbs.
