I didn't know where else to post a minivan question, as you don't seem to have a minivan forum. I have a 1991 Toyota Previa minivan with a reverse light problem. When you move the gear shift lever to reverse, the lights don't come on, but if you move the lever slightly towards park, the lights will come on. I was told there is an adjustment somewhere, possibly near the neutral safety switch. Could this be an adjustment problem?
