01 quad cab 3/4 ton 24v 6sp SLT. The interior map/dome lights stay on unless I roll the interior light switch down to the off position. I have already swapped out both door jam swtiches, the headlight switch module and have individually isolated both the maplights and dome light, and still the lights will not go off unless I turn off the interior lights with the switch. Any help or suggestions??? thx, Ernie

 

IS it just the map lights or all three

 

All 3 stay on. Both map lights and the dome light.

 

by the headlight switch module do you mean the switch on the dash?
