obd trouble
my check engine light came on so I went to (insert local auto store here) to get it read. well my obd wont read. I checked the cigarette lighter fuse and it was indeed blown. so I replaced the fuse, still wont work. I popped the obd from the housing, checked the wires in the back of the plug everything looks fine. nothing is gunked up or blocking any individual port. im stumped, any help would be greatly appreciated! thanks
