2003 v6 Toyota 4 runner I have replaced the relay and checked the resistor blower fan looks good, what else can I do?

  • Welcome to Motor Vehicle Maintenance & Repair! At this point would either boil down to the switch or the wiring. At least that'd be my best guess. – Pᴀᴜʟsᴛᴇʀ2 Nov 11 '19 at 20:41
  • You need to diagnose the problem. It could be the speed control (often that's the problem), the motor itself, the load resistor, the wiring, or the connectors. – jwh20 Nov 11 '19 at 21:21
