    I have already replaced all the bulbs and checked the fuses, nothing blown. My concern is that this TIPM unit in the front controls all of the lighting on the truck and I am beginning to lean towards that module being bad. I have read elsewhere several times that this unit is prone to corrosion and shorted circuits...

    The weekend came and I finally had some time to trouble shoot the problem... I thought it was my TIPM as dodges are known for having issues with these circut boards because they are in the enging compartment and have small holes in the bottom of the case to let moisture out but, inadvertantly, they also let moisture in.. I traced power to the TIPM and not out.. I knew I had an issue. This is a sealed unit and Dodge designed it so that you can not get into the case easily. I disconnected the battery, took out the case(fuse box) which consists of a nut and a bolt, removes the six wire harnesses going to and from the unit and laid it on a table. Removed all of the relays and fuses and drilled out the plastic plug welds(3 of them), removed the computer module from the side (4 screws) pryed back the sides and popped the case apart. Gently pryed the circut board from the stack of laminate boards (its held on by 7 prongs)and cleaned the board off. I could easily see where the corrosion had ate away the copper strip providing power to my turn signals and head lamps. Cleaned it up real well with some alchohal on both sides, scraped away any corrosion and cleaned the copper to take solder, soldered a jumper wire where the corrosion had broke the connection and did the same where there was other corrosion but it had not broke the connection yet. Cleaned again with alchohal, checked for continuity with an ohms meter where I had made repairs. Used RTV silicone and lightly coated the repair spots to prevent new moisture/corrosion. Put the unti back together, installed it in the truck and presto! It works like a charm.... Saved myself $533.00 for the part and $285.00 in labor for a grand total of $818.00!!! Took me 2 hrs to make the repair from start to finish, cost me nothing.......

first thing to do, go with the replacement of the light bulbs, high beam and low beam are two different fillaments on the ligh bulb, as for the rear also replace the bulbs, when your flasher rellay flashes faster, it means that there is less drop of current in the circuit, like only one light bulb working.

Hi the first thing I check on for anyelectrical problem is a bad ground connection. Follow the headlight wires as far as you can, even when they disappear into a larger covered loom at random places, maybe even right next to each light, you will find a wire or several attached to ground, could be a inner fender, engine, etc.. sometimes a inner fender ground is just a selftapping screw, It may be rusted out or just loose. Headlights work through relays that are also located in the fuse boxes. I assume you have checked both fuse boxes, in the truck and under the hood, good luck, Chuck

The headlight switch gets power for the headlights from a 50amp fuse.
The fuse powers the headlight switch then the dimmer switch breaks for high and low beams. So if the high beams work, the problem may be with the dimmer switch.
The dimmer switch is made into the turn signal switch on the column. You would need to check the low and high beam circuits at the switch for power.

I have a 2004 ram 2500 and all my lights work except for low beams. It is not in the switch, I haver replaced the switch with no change. This is a circuit problem with these dodge pickups. I haven't firgured out what it is but it isn't the switch. and unless the low beams and high beams are fused seperate, it isn't a fuse problem either. i have looked for a fuse and can't even find the fuse for the headlights. Im lost like you!

Running day lights,

I had a similar problem with my 2001 dodge 3500, the first thing I would check is to make sure that you in fact have high beams working when the light switch is turned on. The DR Lights use the high beam element of the headlamp and if they are burnt out then the DR lights won't be working. My problem was that I had no low beam headlights and everything else was working, turns out both low beam elements were burned out at the same time, replaced the bulbs and all was well. If this does not solve the problem then see if you can get a wiring diagram for the vehicle and go from there. It would seem strange that both of my elements burned out at the same time but that is exactly what happened.

hope this helps
