I see several threads concerning replacing factory LED bulbs for side markers but none with my issue. Long story short, I did not come to the forum as I always do, when my side marker went out. Instead I purchase the replacements below https://www.ebay.com/itm/For-2003-20...72.m2749.l2649 and threw away my factory ones when all I needed to do was replace the bulbs in the housing. I've seen quite a few threads on how to do that since...now I'm stuck with these. problem is, when all are lit, my brake lights do not work. Also, the two arrows on my instrument cluster stay lit. With the rear only hooked up, my brake lights do work. Please help me figure out how to get all working, trash man has already passed so no recovering the old ones.

 

Mmmm

The eBay site says "heat less than half the original car" which means half the current, so its hard to see why this shoul cause any issues.

If you look at the wiring diagram (see attached) you'll see the marker lamps are in parallel (Light Blue wiring) with the other turn-signal lamps.

The LT_BLU Left Turn Signal "Circuit 3" page1, links to LT_BLU circuit 3 page2, Junction S210 (middle of page2) links to the following:-

1. Left Rear Marker Lamp (F3 C1)
2. Left Turn Signal Indicator (Instrument cluster) (B1)
3. Left Front Marker Lamp (E1)
4. Left Front Turn Signal Lamp (C4)
5. Left Rear Turn Signal Lamp (B3 C3)

Note Circuit 8 (1320) is also in Light Blue but is not related to the turns signals.

The only possibilities I can think of are:-

• The markers are drawing more current than specified or them is defective, but no doubt you will have swapped them with the rear ones for sure. Even so over current should take-out the fuse rather than affect the stop lamps.
• Either the ground point G100 (Left Front Frame Body Mount) and/or G401 (Left Rear Frame Body Mount) are corroded/dodgy causing strange effects.
• May be the Marker Lamps are wired differently than shown (note pdf is for a 2004) Look for any changes and/or mods

I seem to recall there was something about the side markers flashing "out-of-phase" with the front-turn signals, but this could be for other markets. I've looked but can't find the thread.

Things to try:-

• What happens with only one of the front side markers connected?
• What happens when you unplug one or both front-turn signal lamps?

If you could measure the current drawn by the new markers, then perhaps someone with the old style one could do the same so you can compare. Alternative contact the supplier, they may be willing to help and it could be good business for them (I have an issue with one myself)

Please keep us posted..

 

The side markers do flash opposite of front markers no? I am surprised they are causing issues since both are LED so resistors shouldn't be needed. If you hook each one up to straight 12v they turn on without issue? Do you feel one of them getting hotter than you feel they should? Something has to be wrong with them since they are the new addition.

 

Thank you both, I will keep you posted on findings.

 

Check the polarity of the front marker wiring with a meter and see if its reversed compared to the rear markers.

Also, from the wiring diagram, the filament lamps connect to GND whilst the LEDS connect to +12V thus the turn signal must have three levels:-

1. +12V Bulbs ON, LEDS OFF
2. GND LEDs ON bulbs OFF
3. No Voltage (disconnected) BULBS OFF, LEDS OFF

This is why they bulbs and LEDs operate alternately.

Your fault is curious, I'd be tempted to check G401
