After replacing the ignition switch the gauges, wipers, dome light, gas gauge, door locks, and speedometer stopped working

Hi,

The one thing that all the components you mentioned have in common is they are controlled by the body control module. If you look below, I attached three pics. The first one shows the location of the junction box and body control module (BCM).

Pic 2 shows the relay box. I need you to check the relevant fuses first. Make sure the fuses are good. In addition, check to make sure there is power to the fuses.

Here is a link to help:

The last pic shows the BCM. It is behind the right side kick panel. That is the moulding where the passenger's right foot would lean against. Note: there are three connections. If the fuses are good and have power, confirm the connections at the BCM are tight, clean, not damaged, and not corroded.

Do this and let me know what you find.

Take care,

Joe
