obc light replacement
here is a link

basically there are 4 screws (one at each corner) that hold the obc in. They screw into the insturment besel from the back (so if you could be inside the dash looking toward the truck then you would see the screw heads).
By taking out the radio and some paneling by the glove box you can sort of get access to them
USE A MAGNETIZED SCREW DRIVER, YOU DO NOT WANT TO DROP A SCREW BACK THERE
should take about 45min to an hour if you go slow and try not to break anything.
good luck. oh and I agree it's the cat.
