Light troubles

[luckydog8]

The lights on my '03 2500 started acting up this week. My left front headlight went out, I changed the bulb and still no light. At the same time, 3 of the 4 turn signals stopped working. Only the right rear works. When I couldn't find any lose grounds, I replaced the turn signal switch which didn't change anything. With nothing else obvious to try, I ordered a new FCM since mine was original. That also hasn't changed anything. Does anybody have any ideas where to go next? Thanks.

The IPM on these trucks has given problems in the past. Unplug all the bulkhead fittings under the fuse box and check for corrosion. Could also be internal to the IPM.

Do you have a snowplow on this truck?

 

[luckydog8]

No, I don't have a snowplow. I've checked all the connections I can find for corrosion and didn't see anything.

PDC - PDM Light troubles resolved??

Hey Luckydog8,
did you ever find a solution for this? I'm asking because I have an '04 with a similar driver side headlight problem. The light is out but the bulb is good.
I've read in another blog (http://dodgeforum.com/forum/3rd-gen-ram-tech/212099-front-control-module-fcm-8.html#post3188845 See post 73 from reneek ) that the common culprit is the Power distribution center. That whole blog I've referenced is about problems with lights and the PDC being the fix.
Surprisingly the same problem hasn't turned up here in any volume. I tried some creative search keywords to try to find it but no joy.

I'm hoping that some one reading this can let me know if the replacement part 68005478AA (for the '04 2500) has really been discontinued!!!
Let me know what you did to get it going again. I'm on the fence about disassembling the PDC ( some say PDM) to look for broken traces, because the truck is my daily driver and can't be without it.
Cheers
Fred

The lights and other peripheral's are controlled out of the FCM, the electronic part of the PDC. If you cannot see corrosion on the connection to the fuse box it is probably internal to the FCM where the problem is. I think Doorman is making the replacements of these parts now, might want to check parts stores or Rock Auto for it.

What is the going price/source for a FCM?
