Hi,

I have 1995 Nissan Hardbody XE w/ 3.0 V6. I had an oil change service done to the truck yesterday morning. However, last night, I started to have this problem with my truck:
- I can start the engine as usual and easily.
- The headlights are working great both low and high beam.
- The windshield washer and wiper are working great too.
- All the things inside the cabin are suddenly not working (no dash light, no instrument
light, AC - Not working, CD player - Not working, Cruise control - not working, horn -
not working, turn signal - not working, hazard lights - not working). It's like there is no
power to these systems.
- The tail lights are not working either.
- I look the fuses for the AC, Audio, and room light. They are not blown (visual check).

Heeeelllppp, What is going on here? What should i do?

Thanks
