Antitheft alarm goes off at random when car is parked. Interior ceiling light and cargo light stays on unless turned off with switch. Ilumination dimmer switch does not work. Rear washer and wiper does not work. Wiper motor is ok. Is it possible that the Alarm and Relay module is deffective?

Hello

It looks like all of the things you are saying go through the Alarm Relay Control Unit located above the right kick panel. The only thing that gets me is your dimmer switch is totally out. I wonder if that is affecting the other things.

I have attached both wiring diagrams for you to look at.

If it were me, I am sure the dimmer switch is less than the Control unit. I would see if I could connect the wires on the dimmer or disconnect them from the switch and see if that made a difference.

Then look at the alarm control. The manufacture doesn't provide certain data on the alarm system for obvious reasons.

Does this help you at all?

Also, if you need to get back with us on this, I have attached the Rodeo models we look at - please let us know your specific 4WD Model and the specific engine size by liter and the 8th digit of the VIN
