Hi there I have an '05 Grand Caravan and the turn signals are all messed up any help would be very much appreciated.

Issue:Signal Left turns on the right signal, signal right turns on right, with Switch in the middle position (off) the right signal turns on. With interior lights all the way up (rear interior lights on only) the turn signals shutoff. go down one notch the left turns on. anywhere in-between off and second notch the right signal turns on.

My battery did end up dying and never had the same charge again. Had to boost multiple times. but alternator is good.

Parts Replaced: Front Control Module (FCM), Multifunction Switch/Turn Switch, Headlight/Interior Light Switch, Bulbs

Tried Fixes: Inspect remote start wiring, grounds with continuity test, cleaned contact on bulbs and sockets.

I can turn all signals on with hazards though.

Thanks In Advance

Faulty battery so start with.. No power drives the electrical system nuts...

 

Take a known good bulb from the other side and swap them, if the bad turn signal now lights up, replace the bulb. If it doesn't light up, you'll check for good power and ground at the socket, if you don't have one or both, then you'll cسheck your fuses and wiring harness for dam

 

Another thing that really helps mess up vehicles electrical systems is good grounds and you need to be on the lookout for loose electrical connections and electrical wires that have been chewed up by rodents. I have a family member that just sold a low mileage Chrysler mini van because of this. So when you do your bulb swap look for evidence of damage from rodents and other problems.
