2005 Dodge Grand Caravan has front turn signals that flash fast and dimly, rears are bright; emergency flashers work normal speed, but fronts are dim; if headlights or fog lights are turned on, then front turn signals or flashers do not light at all.

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.

Usually that fast blink is a good warning that one of the signals is out. Double checked that bulb is same # and all that ? What number is on the bulb? if it's 2057 or 3057, try pulling wires on side of bulb with fingernail, outward to make better contact, to see if that helps.

SOURCE: front turning light does not work, i replaced the bulb, and when i turn the truning signal does not turn off.

Sounds like you have a bad ground. Follow the wiring harnesses under the hood and in the trunk, there should be a ground wire going to the chassis or to the body. If they are all clean and tight, you might be looking at a bad light socket.

any time you see a dim headlight it is caused by a loose,or missing,or dirty ground to that light.

Hello Durant.
Your rear signal lamps are turned on by the body control module (BCM).
You could have some broken wires from the BCM to the rear signals or the BCM isn't providing power to them. The BCM must be getting a signal input because the front ones are functional.
If you want to trace the wires here are the colors you are looking for.
Left rear wire is white/dark green.
Right rear wire is white/brown.
You may need to have your BCM scanned to verify.
If you would like more information to solve this yourself ask me.
