112v power outlet/inverter not working--anybody else have this problem?

    For the first time I tried using the 112v/400w power inverter in my new-to-me Tacoma and when I push the dash button, nothing happens. The lights in the button do not light up, and the outlet in the bed does not supply power. I have a 6spd and have tried turning the inverter on with the engine on and off, in and out of gear. I checked the fuse that says pwr outlet by the steering wheel but it was fine. Has anybody had a similar issue or know where there might be another fuse to check or maybe a relay? Also is the button supposed to pop back up like the clutch start cancel button, or is is supposed to stay depressed like the locker and fog lamp buttons? Thanks.

    I've done some searching and it seems there are a few other posts on this, but nobody posted any solutions...so, did any of you find and fix the problem?

    In the fuse box in the engine bay, check the 100A fuse closest to the engine. It is labeled AC SKT.

    The 100A AC SKT fuse looks good. Do you know which pins/slots I can connect where the AC SKT relay goes to bypass it (test if either the relay or switch are the problem)?

    I do not. I haven't had any issues with mine, but I vaguely recall something about a possible internal fuse inside the inverter. I think I also read something about a possible bad switch.

    I looked up some relay schematics and did some testing. If I jump the two perpendicular slots, the inverter puts out power. If I jump the two parallel spades on the relay to the battery, the relay clicks, so the relay should be good. Looks like the switch in the dash is the problem, unless there is a feature in our systems that I am unaware of that would cause the switch to not light up and not flip the relay. Does anybody know where to get a switch other than the dealership?

    Well I did some more testing and found out that the switch in the dash is fine--it is a super simple design, and honestly I don't see this switch ever failing. I also figured out what others have figured out--that there is a switch of some sort built into the inverter that controls the relay in the engine bay. I also found out that there was a loose plug under the center console that was causing my inverter to not turn on...so I plugged it back in and problem solved! Of course, while I had the center console out I had to do the 400w all the time mod and install two power outlets in the back of the center console (naturally).

    Great! Glad it was something simple. Good idea on the 110V outlets in the cab. It should have been a standard feature.

    ok I am have similar problems with my 06 tacoma. I have replaced the switch and that was not it. I have jumpered the relay under the hood and the system does turn on and works but is not able to figure out where the problem is that the system does not work like it is suppose to.

    Is there a wiring scnapic or another modual that comtrols this system that I am missing. I tried the link of the 400W all time and it did not work. And I like the idea of a outlet in the car so I will do that once I can get everything working

    PLS Help.
