Hey guys im new to the 4 wheel drive scene i have an 02 4 door and 4lo locks in and 4hi wont the light keeps blinking and never locks in can anyone help

 

My 2000 did this and I had to replace the Transfer Case Control Module. Not a hard repair, but the TCCM ran like $400. I understand that these modules stayed the same through some time in 2003 when GM updated, but until then they were rather problematic.

 

ok where is that located at like i said in new to this game. and where can i get a new one

 

I got the same problem. My 4lo works fine...but 4HI doesn't go in. but i've heard it was the solenoid tho. not just the module. does this ring a bell at all?

 

Check the fuse. I think its no 19 and I bet my *** its blown. Had this several times now onmy 96 Blazer 4 door. Still trying to figure out why
