My 2nd Previa bought but haven't picked it up yet has starting issues. The current owner said "Van doesn't start, may need just battery, fuse, relay or starter." Found the location the fuse but not the relay. Toyota stealership parts department manager(young buck) said the relay p/n 28300 is $165+ tax! I asked him where it is located and no one in the department knows:-(. I will try to diagnose and fix it myself when I pick it up.
