A quad driver is what turns the fuel injector on and off. They're part of the PCM and are not replaceable separately. You have to buy a rebuild PCM. BUT, do not do that until you find out WHY the quad drivers went bad. Usually it's caused by a short in the fuel injector coil windings or a short in the harness. If you don't fix it and just replace the PCM, you'll burn out the new PCM

You would have to replace the multifunction switch on the driver side of the steering column. It is not real expensive and if you are handy it is not a real hard job.

That handle jsut pulls straight out of the multifunction switch.

Try lubricating the door latch mechanisms on all the doors.
