4WD blinking light issue

Just became the proud owner of a 1999 T4r 4x4. Unfortunately my second issue has been the 4x4 blinking light scenario. Have followed the procedures outlined to engage four-wheel drive and have gone through the procedure several times to no avail. Then, I disconnected the battery reconnected, no change, check the fuse, a okay. Is the next step in the troubleshooting process to pull the actuator off clean it? I have also read in another thread that there's a possibility it's the switch on the shifter that engages the four-wheel drive. Any thoughts and or suggestions I know this is probably been gone over a million times already but I can't figure out how to find previous threads. Anyway I can feel it going into four wheel drive when I shift the four-wheel drive into four low, oh I can feel it! Then when I go to shift it back to H2 the lights go off temporarily but then they come back on and start blinking??

Any codes from OBD?

 

You know I have not checked that yet I will do that before I break down and start pulling stuff off, in fact I can run through that this evening, thanks for the heads up!
