Signs of a faulty part

If you notice any of the following, the part likely needs replacement:

  • Intermittent power loss to accessories or the engine while driving
  • Certain positions (accessory, run, start) not working reliably
  • Key needs to be jiggled to maintain power

Installation information

Requires the ignition switch assembly to be at least partially disassembled for access — often replaced as part of the full switch rather than separately.

Frequently asked questions

Years of repeated key turns and the electrical current passing through them gradually wears and pits the contact surfaces, reducing reliable connection.

  • I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

  • No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

  • Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
