help!! can't get 4x4 working

[parrothead]

I just purchased a very used 93 explorer.I invested about $800 after the purchase withthe mindset that it would make a good work vehicle in upstate New York. My primary problem now is the 4x4 is not working. I've spent about $100 on junkyard parts (4x4 modual in rear cargo area and a used transfer case shift motor)neither of which has solved the issue.Worst case I have backups now. There is no response what so ever when I try to turn the 4x4 on.no clunk. no lights.nothing. I took the dashboard bezal off to tinker with the switch. After I did that I was able to notice that regaurdless or not the switch was plugged the 4x4 and the low range lights would come on AFTER I killed the engine, but very dim. I could not tell with the tinted bezal on it. Bottom line I'm going to buy a switch 2morrow. But what else could cause this. I would prefer to do this myself for the knowledge but I'm running out of good weather and would like to have 4x4 ASAP. Thanks in advance

Read the shift motor rebuild thread as it is most likely the problem you're having... The quick test is to press the dash 4x4 high button and then listen for the relays within the 4x4 control module in the rear hatch area... if you can hear the relays then the module has recieved the 4x4 button input, but has detected an electrical fault (most likely the geared sensor positon is out of it's operation range) and defaults to doing nothing.

Many used shift motors already have this problem.. Take apart the old one and look for a busted stop bumper...

nothing I have no clicking from the control modual no lights nothing. I replaced the module w/ a juckyard part. I've been told that these hardly ever go out. It seems that no electricity is getting to the system. I don't see any leads that could be shorted and the fuse in engine compartment is good. This is driving me crazy. I'm going to rebuild the motor tomorrow and replace the switch just to be sure is there anything else that I can check.(other than wielding a wrench the back of the t-case as a makeshift shifter)LOL

You say seems no electricity is getting to certain parts. Sounds like you do not have a multimeter?
