Hey guys looking for some help. I have a 2003 1500 and im having 4x4 issues, first all the lights on the switch lit up the flashed a few times then went out, then the service 4x4 light came on. i bought a used "working" tccm and that didnt do the trick, bought a new switch and that did nothing either, bought a motor and plugged it in but didnt install it fully and that did nothing either. checked all wiring and fuses and all is ok. ive driven the truck a few times since then and every once in a while the lights on the switch will flash very lightly. any info would be great. Thanks!

 

does the 4 wheel drive work if so could just be a bad light in switch
