: the contact stated while driving in normal conditions, the electrical system does not properly work. This occurs at various speeds. While the accelerator pedal is depressed no problems are apparent. However, when the accelerator pedal is not depressed the heater blower does not blow and the exterior and interior lighting is so dim that the contact has visual problems while driving at night. The vehicle was taken to the local dealership numerous times for inspection and repairs. The dealer replaced the alternator although that did not remedy the problem. The dealer can not duplicate the problem; therefore no additional repairs were made.
