I have a '98 XLT 4X4. When the passenger AB switch is in the ON position, the AB dash light flashes 25 and the passenger AB light goes off. When I put the switch in the OFF position, the light comes on and the AB dash light does not flash. Anyone know what the problem might be?

Thanks

 

I don't have my manual with me right now but I recall this being discussed a few days ago and someone said its a bad passngers deactivation switch. Do a quick search to confirm, I think the original topic was about a code 27.
