My 4 wheel drive has quit workin. Turn the switch an nothin at all with hubs in locked or unlocked. Any ideas

 

CAn u hear the elcetric motor move?

 

no i dont think so

 

its either the motor is bad or a bad connetion

 

that cause dash light an everything not to work?

 

When you turn the 4x4 on with ac on does it start to come out the defrost vesnts? You either have a going bad vacuum pump or more than likely a leak somewhere on the vacuum lines.

 

Check your fuses. Then crawl under the truck and unplug the switch at the T-case and fill the connection with Dielectric grease, plug it back in and try again.

Sounds like a blown fuse... Vacumn leak would NOT keep the T-case from engaging, just keep the 4x4 from locking up.

 

I checked my connection, an only found one fuse for the 4 wheel drive and it was good. Am i missing a fuse or does anyone have any other suggestions? Thanks

Did you do any trouble shooting at the connection? Is your vacuum pump working?
