2004 Dodge 3500 crewcab dually, headlights won,t switch to highbeam,when signaling left sometimes dash right indicator light will flash and sometimes nothing happens and sometimes signals work fine also at times shift indicator doesnt move when I shift and I need to move shifter back and forth inorder to make it move when this happens sometimes horn will beep on and off any ideas

SOURCE: I have no parking lights

they have an updated headlight switch at the dealer with the wire harness if you replace both these items your problem will be solved..

Did all these problems happen all at one time?? If so you may have a bad body ground. Try running a electrical wire from the (-) negative side of the battery to the body and see if this works. Be sure this wire is to a place with no paint as low voltage electricity will not flow through paint.
A). If not try replacing the turn signal flasher for the turn signal problem. This is usually the culprit and it's easiest and cheapest to replace. The turn signal flasher will be found under the driver side dash next to the hazard flasher. Turn the hazard flasher one to locate it. If you want try swapping the turn signal flasher with the hazard flasher to see if this fixes it. They are the same style flasher.
If this doesn't work you may a faulty turn signal switch or some wiring issues.
B). It could as simple as the head lights bulbs need to be replaced, it's rare but I have seen when both bulbs blew at or near the same time. If your able check the voltage at the head sockets.
C). Could be a bad blower motor or switch. I'm not sure if these models have a resistor block or not. The resister block controls the electrical current going to blower motor which controls the speed of the blower fan.

check to see if there are any pinched wires behind the lights/Please rate my response thank you very much

the flasher is under the dash on the drivers side that is definitely a possibility but it also could be a multifunction switch

replace the turn signal switch it self, mine did the same thing with the left turn signal, put in fuse and it will continue to flash... went to junk yard pulled one out of a 97 avenger just like mine, swapped them out and now it works fine. looked to be like some corrosion... to repace: 3 screws under columb, 2 screws on side of signal switch (black plastic side). unplug and replace
