1998 Porsche Boxster windshiled wiper stopped working

SOURCE: Windscreen wiper problem

The left and right wiper are on the same fuse and same switch, as well as the same wiper motor. That being said- if one works and the other doesn't, the fault lies with the wiper motor itself, or with the wiper shaft (where the arm connects to the motor.)

A wiper motor has 2 output shafts that either wiper arm connects to. At the base of your left wiper arm is a small cap. (there's one on the right side too, but let it be since it is working!) Remove this and unbolt the wiper arm from the output shaft and pull outwards to remove it.

When you examine the assembly you will notice that the wiper arm and output shaft are splined, which allows the rotational movement of the output shaft to be transferred to the wiper arm. It is common for the contact area of these splines to become damaged. This is often caused by excessive drag on the wiper arm and blade. (ie running the wipers over a dry windshield, or trying to unstick a wiper blade that is frozen to the windshield)

The 1st test is to turn on the wipers and observe the now exposed wiper shaft. Does it spin at all? If it does then problem is damaged splines on the wiper arm. (the arm is made of much softer metal than the output shaft, which makes it easier to repair this problem.)

If it turns out that the splines are damaged the 1st thing to try is to clean them up a bit. I have had luck using a very sharp awl to trace the path of the splines. A locksmiths file is very useful if you need to reshape them a bit. After cleaning up the splines reattach the wiper arm and see if it works. If not the arm will need to be replaced.

Now, if you test to see if the output shaft is turning and it is motionless while the other side wipes away, then the wiper motor and assembly needs to be replaced.

When reinstalling the wiper arm do your best to make its position match the other arm. press it onto the shaft and run the wipers a bit to make sure it is where you want it before bolting it back up.

This is a common problem. Your alarm was on when the battery went dead. When the alarm activated, the hood/bonnet opening lever locks to prevent thieves from opening the hood in case the top is down. Some boxsters have a jumper post the pulls out near the fuse box. However, I do not think the 1997-1999s have this post.

Buy a male-to-male cigarette lighter adapter at the auto store. Connect between your car's cigarette lighter socket and the other car's cigarette lighter socket. Do not try to start the ignition or the any other electronics. You should not even need the key in the ignition. You should be able to pop the door locks with the remote and open the bonnet.

It sounds like it could be the plastic connecting bit that links the lock tumbler lever to the rod that operates the door lock mechanism, has broken or become disconnected. To check, you will need to remove the trim on the inside of the door, after removing any screws and the inside door lever and window winder.
Once you have the inside trim off and the plastic sheet, you will see an access hole for the door mechanism and the lock tumbler. It should be attached to the actuating rod by the aforementioned plastic bit. If plastic bit appears OK try re-attaching it or replacing it if broken. If the lever part of the lock tumbler which attaches to the rod is broken the lock will need replacing.
