Hello,
This is my 1st time posting a thread, so I apologize if this is a repeat.

I have a 2005 Dodge Grand Caravan, that is an absolute joy to drive. Recently, my front right turn signal stopped working ... I can hear a fast turn, indicating a burnt-out bulb. In spite of me replacing several bulbs (even switching from the left turn signal, I have come to the conclusion that there is something more to this. Then, about a week ago, both my headlights started dimming, so my mechanic suggested replacing the bulbs with LED. Last week, as I head out-of-town, I started noticing that the headlights were dimming. So I switched the headlights OFF ... then ON ... then OFF ... then ON. At one point, the headlights came ON, however, the dashboard lights were OFF and the switch was in the OFF position ... scary! I then turned the HIGH-BEAM ON and then everything appeared to work fine. The LED lights worked just as they should ... bright.

My mechanic thinks it is some sort of an electrical issue, given the age of the car ... he mentioned something about the relay switch(?), corroded wires, or ???
He has categorically ruled out the LED bulbs.
He can't even scan for any error codes!

My questions:
1) Has anyone encountered something like this?
2) Is this indeed some sort of an electrical issue ... especially given the fact that my right turn signal started behaving erratically before?
3) Are there any error codes that one can check? My mechanic says it's like searching for a needle in a haystack.

Thank you!

 

I do not claim any special knowledge of this however I have done some research as I have a similar problem with my 2016. It seems that there is a ground wire which is located on the lower radiator mount area that corrodes badly and can cause this type of problem. I am not able personally to chase this on my van and have yet to enlist help but maybe this will give you another idea to check. Best of luck.

 

There is some kind of computer thing in front of the fuse box which is next to the battery. Years ago, I lost headlights alone one night for no reason in my 2004. Thank goodness my hazard lights are super bright stock, they let me see enough to go home! Anyway, that box, which is in front of the fuse box can be removed, I forgot how, It may be screwed on, but it is not hard to remove. you'll see lots of electrical pegs. Clean those pegs, perhaps bend them just a wee bit, perhaps put a light coat of grease on each one, and reinstall. There are threads about people losing headlights online, perhaps even here. Good luck.

 

What I meant was, there are threads with similar problems online and that THIS was the fix for it.
