hello. i know this subject has been covered many many times on here but after searching everything i could find i still haven't found anything that might point me in the right direction. i have a '99 ranger xlt 4x4 ex. cab and i'm having trouble tracking down what is preventing 4hi or 4lo from engaging. it worked fine the first time i locked it in back a year ago and i noticed the front hubs weren't locking in. checked all vacuum lines and testing solenoid and it turned out to be a simple blowed fuse which i replaced and everything worked fine. a few months later i have the need to lock it into 4wd so i turn the dash knob to 4hi, which engaged, then to 4lo, which also engaged. pulled out to where i could unlock it, turned the knob back to 2hi and the 4hi/4lo lights started flashing and the t-case would not come out of 4lo. i limp it home, remove the t-case shift motor and do the inspect and clean and still no luck. being my only ride i had to use pliers to turn the shaft back to 2hi. i recently purchased a brand new shift motor with no luck. dash lights just blink 5 or 6 times then stay lit. i'm a certified automotive election so i found a diagram of the dash switch and checked with my dmm and it checked out fine. all fuses are fine. front axle actuator is working properly, or at least theres a vacuum change which i assumed was normal operation. my only other guess is the module behind the radio but from what i've read these rarely go bad. if someone could offer thoughts on what to check or any incite would be greatly appreciated. i've had 8 rangers but this is my first 4x4 so i'm kinda in the dark and this seemed like the most informative site i've ran across. thanks in advance.
