That does sound like a bad module. hopefully it hasn't burned the motor. You might want to dig around for spares or at least a source of them just in case. You could need them in the not distant future.
The car in the cave picture had the fender off for other work. It was a good clear picture I was given to show the module location.
The fender can stay on.
The inner fender is pretty flexible. You may want someone to help hold it while you work. The edge of the plastic is pretty rough and can scratch you up good.
If you have a stubby or right angle tool, I think you can reach it from under as well. Either one is fairly awkward.
Be alert. The world needs more lerts...
