02 caravan no turn signals

[putter]

they are flashing on the dash fine with the switch or the hazard button just not flashing on the outside. the turn signal switch seems to be operating fine wipers high beams all are working good. cant seem to find the the relay for operating the signals.

any input would be great thanks

[jeffreyd]

have you checked the bulbs

[fishhuntwork]

Do you have a trailer wiring package on them? If so start there and like jeff said make sure the bulbs are good.

[putter]

all the bulbs were good and i bypassed the trailer wiring thats why i think its a relay or the bcm.

thanks for the input

There is no relay. The turn signals are controlled by the Body Control Module. There are relays but they control the trailer lighting only.

Could still be the multi-function switch or a water leaking issue on the BCM (or just something bad went wrong with it).

Good luck!

My BCM went out in an '02 Dodge Dakota, so I wouldn't be surprised.

If it where the switch they would not be blinking on the dash. The Multifunction "switch" isn't really a switch. It's more like a sending unit or sensor, It supplies three different signals to the BCM depending on the position of the lever. The BCM then decided what bulbs to send power to.

[Shack]

Ok I just picked up on the fact the lights on the dash are still blinking.

I am a little slow today, even for being myself.

[putter]

So is there away of testing the bcm? I wouild think that if the switch is sending power to the bcm and then the bcm is turning on the dash lights that it wouldbe a wiring issue that i cant find or is there two diffrent out putts on a bcm?

thanks putter

You can check the output on the Wht/DkGrn, Wht/Brn, Wht/Tan, and Wht/LtGrn at the BCM connector 2 pins 1,2,3, & 4. If there is no power there than I would be suspicious of the BCM. If there is power there than you have a wiring issue. The right and left turn indicator are on a separate circuit from the BCM. They should be on connector 4 and pins 9 & 17 (wht/tan, wht/lt grn wires)

thanks airjer

i will check it if work would ever slow down so i can get back to it.
