Thanks for the help guys. Helpful information.

 

I'm not sure if you are still around BCP but the same thing happened to my bf's car today and I read exactly what you wrote and he did everything including putting his keys in his pocket and BAM! wouldn't you know it WORKED!

If you see this message I just wanted to thank you SO much for explaining every step in detail exactly how he needed to do in so he wouldnt mess anything up. I know it was almost 10 years ago that you posted but just maybe somehow you will know how much you have helped me/us.

 

So I picked up this 06 Dodge Magnum 2.7l with a locked up engine. Swapped to a 4.0l and it runs amazing now.
My issue is I had several electrical issues. Come to find out someone had been jacking with the front fuse box. Missing relays & fuses. I have all that straightened out now. But, my headlights are jacked up. Basically, the high beams stay on all the time if the car is running, headlights on or off. Once I turn the headlights on, all four headlights come on but I can't switch them with the M/S.
High beam indicator stays on constantly. I have turn signals for the most part. Dash indicators work, all but 3 exterior lights work. And it worked until I swapped the Front Control Module.
The original problem(s) were: #30 fuse in rear fuse box blown and was missing #27 fuse in front fuse box, Front Control Module fuse. All that is fixed. I have swapped FCM & Headlight switch. It doesnt matter which ones I use, nothing makes a difference. Headlights and indicator used to switch on/off initially but wont now. Tried the battery disconnect but didnt remove key. No difference. Will try removing key.
Any suggestions?
FIXED SOLUTION:
I assumed that since switching the Headlight switches and Front Control Modules didn't make a difference, there was only one item left that could have been the issue. That was the Multi-function Switch in the steering wheel. I picked a used one up from the salvage yard, installed it, and now the headlights work properly.
There are 3 main elements to the head lights: Headlight switch, Front Control Module & the Multi-function Switch in the steering column.
There are also 4 fuses that are part of the system too. Fuses #5 & #30 in the rear fuse box. #5 feeds #30 supposedly. #30 is power to the FCM.
Then there are two fuses in the front fuse box. #25 & #27. These are big heavy 40amp & 20amp fuses that are about 1/2" square and about 1" long. They are hard to tell if they are good/bad just by looking at them. Check with a volt meter to be sure.
On the one rear blinker light that wouldnt work, the bulb was bad. It looked good, worked previously before swapping FCM. A new bulb fixed that.
