I have a 2005 Dodge Caravan.

Can some one tell me where the
Turn-light flasher is located?

Thanks in advance.

Some auto parts stores have diagrams showing the part's location on the same system they use to identify the proper replacement parts.

IF you haven't already, use the four way flashers to make sure all the lamps are working, since a burned out bulb can slow or stop the flashing.

I had the same problem with a 1990 Dynasty. I ended up turning on the four way flashers and following the clicking sound of that separate, but adjacent flasher. The change was a bit awkward though as the flashers in the Dynasty were located behind the edge of the fuse panel. I had to loosen the fuse panel and shift it towards the front of the car a bit to get the replacement flasher in.

There is no such animal in your vehicle. The turn signal operation is all performed by the body control module. The turn signal switch assembly, now known as either the combination switch or the multi-function switch has resistors inside. When you turn left, the resistors drop the voltage on the violet/blue wire to 0 volts. On a right turn, the voltage should read above 1 volt. Use a digital volt meter (not an analog meter) to check for those voltage. If you don't see them, examine the connect at the multi-function switch before you replace it. (Fairly common failure point).
