Three problems related to electrical system have been reported for the 2003 Dodge RAM. The most recently reported issues are listed below.
Poor reliability of electrical control and distribution system causes numerous and sometimes intermittent failures of exterior safety-related lighting such as headlamps (low beam and high beam), taillamps, turn signals, brake lamps, and trailer lamps. Problems seem to be exacerbated if vehicle is not operated for a few weeks. Dealer is quoting repair cost in excess of $2000 for replacement of the power distribution center, which is reportedly not a serviceable unit. This high repair cost will undoubtedly cause owners to "take their chances" and continue operating vehicles in an unsafe condition because the repair is so costly and the problems are intermittent. Some users have reported needing to complete this repair more than once over the vehicle lifetime, which further confirms there is an inherent reliability problem with this vehicle's electrical system. Other users report similar issues with windshield wipers reportedly due to the same unit failure. Because Dodge Ram pickup trucks have at least ten different model categories and multiple model years for reporting in the NHTSA online reporting structure, the complaints are spread out and the concentration of problems endemic to this vehicle may not be readily apparent to odi investigators. Complaints may be reported under "1500", "2500", "3500", "ram", "ram 1500", "ram 2500", "ram 3500", "ram quad cab", "ram pickup", "Dodge truck", . . . , all due to the same module failure. Complaints are also spread out among many different complaint categories, further diluting the recognition that there is one fundamental root cause of a dozen or more different failure modes.
The ventilation system failed as is common with these vehicles. Due to weal parts, the, "doors" that control air flow through the ventilation ducts broke. I have slowly replace each of the four doors as they failed. As they went out it affected every aspect of ventilation, including the defrost. After doing some research it is evident Dodge was fully aware of this issue but made no improvements to the system, continuing to sell these vehicles to an unsuspecting public for several years.
After numerous attempts to repair the stalling problem, the consumer would like to pursue the lemon law. The rear passenger outside door handle was loose.
