First, you need to take off the steering wheel. Then, unscrew the cover ( 3 or 4 screws). You will see the switch.

I sure that you need to get loose the criuse contral switch first. Then follow the wiring to unplug it.

About the combination switch, the connector is directly to the fuse box. Follow the wires and find the connector to the fuse box. That connector is very tight to get off. I using a heavy metal wire to take the plug off.

Sorry!!! My English is bad.... Hopefully, you understand!!
