Check the resistance of the new wiper motor, it should be only a few ohms to 20 ohms. If it is not within this range it is faulty.

E26 and E27 which is "Shorted throttle switch signal" and "Open throttle switch signal".
The code E52 just means that the ECM lost power or ground or that someone forgot to clear the code after hooking the battery back up. It could mean a bad computor but not very often. 2 things that come to mind is a bad ignition key or lock cylinder or a faulty neutral safety switch. Try the other ignition key first. Then with your foot on the brake pedal hold the key in the start position and move the shifter slowly from P to D. If it tries to start then the NS Switch is bad or out of adjustment. If it still won't start then you will need to troubleshoot the ignition key/PASS KEY system for an open wire in the steering column. Hope that helps. Bill

sounds like a problem with the fuel getting overheated and evaperating when turned engine off , check the engine cooling system is pumping through the fuel intake manifold section as a starting point, check that the engine cooling fan runs on after turning engine off as this cools the engine down to stop the fuel evaperating in the fuel lines etc

It's just worn out. You can look online or call a dealer to see if you can even find/get parts for it. Best bet is to find a good used column at a salvage yard.

You'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. If needed, you can pull back the weather seal (can't reuse it, but it's not that important) and you will be able to access everything inside the door
