We purchased the van used and thought it just had minor problems (brakes, tires, etc.) we did not know that the lights did not work. Have replaced 4 headlights. For some reason there is temporary problems with the radio, windows, windshield wipers and beeping sounds while the van is either coming on or being driven. There is an electrical issue somewhere and all the people that have looked at it is at a loss of the problem. I would like to know if anyone else has had this problem and what did they do to fix it.
