I installed a new stereo in my 2001 Montero (not the Sport), and it was working then all of a sudden the clock and radio stopped working and the dome lights and power locks don't work either... I checked both fuse boxes and the fusiable links and they are straight, I can't think of what else it could be?

If it helps, I had the yellow and red wires connected and I grounded the stereo to the metal tray in the stereo bay, not sure if there was reverse polarity or not but if that was the case it shouldn't have worked in the first place?

Thanks

 

I am pretty sure the ACC fuse is blown. It may not look blown but it is. The ACC fuse is not a regular little fuse, it is a big one (probably under the hood next to some relays) Replace that and write back to us what happened.
