New ignition switch in about a month ago and now all the gauges does not work

Hello,

If this issue started after the install of a new ignition switch, then it is likely due to a faulty switch or bad / loose connection during the install.
Best course of action would be to replace the ignition switch, as the issue did not exist before the replacement.

Replacing the ignition switch requires the removal of the steering wheel.

Remember to take extra precaution when working with airbag inflator. Never point the inflator to your body.

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
