I recently replaced my stereo and to do that I had to disconnect the 4WD switch. I ended up reconnecting it in the meantime as I worked on the stereo and it worked fine. The last time that I went to put everything back together, it stopped working. First of all, it wouldn't even fit back in to the pin connector. I don't know if the plastic just got warped somehow from not being connected for a while? Anyway, when I finally got it connected again, there is no light on the switch and my dash still says "service 4WD." Anyone have any ideas on what the issue could be? The pins all seem to be ok and not damaged.

 

did you try different orientations?

 

I ended up forgetting that there was another connector that I wasn't using..simple fix. Made me feel really dumb though!
