2002 ranger electric shift 4wd.
The problem is not the shift motor. i tested the motor on and off the transfer case with a battery and it runs fine.
When my truck is running it wont shift into 4wd. i can turn the switch but the dash lights wont turn on and the transfer case doesnt shift.
When I turn the key to ignition w/o starting engine and turn the 4wd switch to 4hi i can hear the soloniod under the dach click and the shiftmotor run and click + the 4hi light on the dash lights up. however nothing happens when i turn the switch to 4low.
I've tried starting my truck after doing this but the dash lites turn off and it must shift back to 2wd.
I have a chip made by Jet performance that i got when i bought the truck. it says it can run diagnostics but it doesnt detect any errors.
