Electrical problem
2003 Ford F250 V8 Four Wheel Drive Automatic 61000 miles
----------------------------------------------------------------
my f-250 diesel interior lams and cargo lamp keep turning themselves on and off. Thus draining my batteries. What do I check to fix this problem, and also which fuse can I take out to keep them off until I can fix problem. I don't know if it makes a difference but my truck does have a keyless entry pad. Thank you for your help up front with hopefully helping me fix this problem.

these trucks have a problem with door latch switches sticking but the module that controls the lights will shut them off if they are on too long to prevent the battery from dying. saying that i would assume its either going to be a bad interior light switch, wiring or the gem module. remove the fuse that says courtesy and this should relieve the problem

there is no fuse that says for courtesy in the manual

ill see if i can get a picture for you. stay tuned.
