I have a F350 2000 crew cab srw with 7.3 diesel. I removed the HID that was installed by previous owner. The factory wiring harness was still intact but now I don't have running lights or dash lights. I still have head lights, brake lights and blinkers... Come on guys I am at a lost..oh yeah I replaced the head light units with factory replacements...... HELP

 

Have you checked your switch and fuses ? I see a lot of light issues after an improper aftermarket radio install also . Just a thought !

 

Checked all fuses and relays....all are good.. So here is what puzzles me. I have headlight with blinkers and brake lights...but no parking lights or rear lights also no dash lights..all the gauges work properly... I have been told that it is a common problem with the f350.. But no one can tell me the places to look to trouble shoot...getting frustrated

 

GEM / BCM may be bad . Some call it different things . Water can kill them from a windshield leak . A wiring diagram would be a big help at this point .
