4wd light, front and rear lock light inop
I am trying to figure out where to start troubleshooting my problem on my 2004 Rubicon.
I can not lock either axle. ( 4L engaged )
I can not hear the air pump run. ( 4L engaged )
I do not get the 4wd, front lock or rear lock lights to light up, even when first turning the ignition on. I don't know if I am supposed to either.
I found the 4wd light switch connector, disconnected. I plugged in the connection, but still no light. At this point I started looking at the wire print.
I jumped the harness at the transfer case (4L engaged) no 4wd light.
I have 12v at the front and rear lock relays.
The axle lock switch does not light up.
Where to go next?
I thought that someone out there would be more familiar with this than me.
I would hate to go deeper than I have to.
The Jeep history: I am the third owner at 34,000 mi. The previous owner claimed everything works. He did have a transmission service done just prior to my purchase. I found the skidplate bolts backed out or just finger tight. and the trans pan very clean. That is why I asked if any transmission work was done. I was told it was in for the 30k service. But he also told me that some light metal was found in the pan. He declined further work because he had no issue with shifting or performance.
