I just recently lost 4wd on my 93 Gmc 4x4. I checked it out and adjusted linkage etc, checked wiring for breaks as best I could, found no power to electric actuator on front axle. Checked fuse-ok. The transfer case does engage when I manually select 4wd as the front drive shaft locks in.I am wondering if one of 2 sensors I see on the transfer case transfer power to the front axle when I select 4wd is faulty and how would I check them?
have the same problem?
