2006 nissan exterra radio will not switch on, fuses check ok

Some have been fitted with a inline fuse , trace the hot wire from the radio to the ignition switch for a inline fuse, check the fuse with a trouble light not a meter as sometimes they go open circuit under load .

Possible shorted transmission harness or transmission shift solenoids. Disconnect the big connector at the transmission under the car and see if the short stops and fuses don't go.

could be the bulb or door switch. I believe there is a switch to turn off the interior lights also.

There are MANY different options when it comes to your system such a XM or Sirius satellite systems and then wiring to the amp & steering wheel controls. In any case it way to much to post until I know what you have in your vehicle. If you still need this information email me at [email protected] with detailed information as to what options and stuff you have for your system. I will be happy to email it to you once I know what all you have....

Sounds like it might have a random misfire. Is the check engine light on? When was your last tune-up?

Have you reset the sensor? Instructions should be in the owners manual.
