One problem related to turn signal switch has been reported for the 2003 Dodge Ram 2500. The most recently reported issues are listed below.
My turn signal stalk doesn't signal properly when actuated. I push up for a right signal, sometimes I get a right signal sometimes I get the total opposite (left signal). This is dangerous. Also on the same lever my wipers don't always turn on properly or the high beams don't activate or don't turn off. However, I strongly feel this is a Chrysler issue because having to do some research on a tdr discussion board it has been realized that there is too much stress on the wiring harness that terminates at the multifunction switch. When the steering wheel is tilted down this harness separates from the switch due to no slack causing it to become erratic, then if you tilt the wheel up it makes a full connection and works properly. There needs to be a recall before this causes an accident!!!.
