Purchased this car used. The OBD2 port will not power on, does not work at all. The non OEM radio also will not give sound, powers on fine.
Tail lights do not come on. Brake lights work.

This is what I have tried:
-Two different obd readers.
-changing fuses.
-new battery.
-has new, spark plugs, oil, oil pressure sender, oil filter, coolant flush, belts and tensioners.

Every thing else works and runs fine. So I am at a loss as to what this could be.

It is at the dealer right now and they want over $600.00 to trace the wiring harness back to the end and try and find the problem.

Is there anything else I could try before forking over this kind of money? The dealer was my last ditch effort, but that is so much money!

Thank you for any help you can offer.

You can go to another garage and see if he is cheaper as a lot of times it is just the connection that is bad. As far as radio if it gets power and there is no code to put in to use it then radio shop would be where to take that.

I figured it out, thanks for the help. We decided to leave it at the dealer. We are running out of time, we have to have it inspected in order to register the car. I will let you know what they come up with.

Lesson learned the hard way, always check the OBD before purchasing a used vehicle! We didn't know until we went to get it inspected that the OBD was out.

So what it turned out to be was a rat or other rodent had chewed up the wires pretty bad. Causing the OBD2 and tail lights to not work.
The mistake cost $1200 :(
We didn't have the time to call around or figure out a different solution since we needed to get the port working for inspection and to finalize sale.

That does happen but its rare. Don't beat yourself up over that one. I wouldn't have checked that either.
