Chrysler Repair: turn signals on 2006 Chrysler town and country, chrysler town and country, left turn signal

Question
blinker is going "hay wire" on a 2006 Chrysler Town and country van, it's sometimes goes on when the left turn signal is turned and sometimes the right goes on.
Changed the bulbs, it must be the brain of the signal does anyone where it is and part number?

Answer
Hi Olek,
The '02 manual, which is the latest I have, shows the circuit is handled by the body computer based upon two different voltage levels that come out of the multifunction (turn-signal part) switch, depending upon whether you choose left or right side. Those voltage differences simply depend upon a voltage divider network using two resistors wired in series inside the switch. It could be the internal switch contacts are dirty/oxidized such that the voltage coming out is not what is intended. So that is where I would start. If you can gain access to the switch and squirt some electrical contact cleaner inside of it that may be the only thing you need to do. I don't see any other explanation that is simple, and unless you find a shorted wired handling that voltage (white/light blue on pin 3 to pin 31 of one of the body computer's five plugs, located under the dash on the left side) you have to investigate the possibility of a fault in the body computer, which is an expensive part to replace without being sure that is the cause. I suspect that the '06 model is identical for this circuit.
