i have a 99 ranger 3.0 that i am having a problem with the hubs.when i start the truck the 4wd lights come on momentarily so the control box should be good.when i select 4wd with the switch the transfer case locks in,checked front shaft and it is locked in.the problem i have is with the actuator under the air box.there is a three wire connector,power to center wire when key is on.there is two vacuum ports on it,one from engine and one to the hubs.i have vacuum going in and intermittently coming out.i do have a new actuator on also.is there any tests or wiring diagrams to help?thank you
