Allooo again

Got a problem but a technical one this time

When i turn on my front wipers, they operate perfectly and smoothly, but when i switch them off they stop right were they are.. they wont go back down to were they are meant to be.. anyone got any pointers on this?

All the technical problems will be popping up here as I am doing all i can on the car.. sorry I am not very helpful with answers to everyone else but im still learning from all the pro's here!

Cheers,
Mark (SparkY)

A missing or non-functioning wiper relay will cause that.

It's in the upper-right.

I had the same problem when I got my car. Check this thread out:

I've actually got the same problem in my car.

Long story short, I've just gotten very good at timing the wipers to park them.

I never thought much on it, but after reading the tips for it I suppose I'll give it a look.

While we are on this topic,

My wipers move when the key is in the on position, and my brake lights arent working, neither are my signals. I was thinking grounds... Anyone have any ideas?

Allo again

I have just been down to the car, and tried playing around with the wiper relay, if i remove the relay it obviously still does not park, remove the fuse ontop of the relay and it does the same, I have just opened up the relay and it all seems to be in top condition, and all the wires on the back of the fuse box are in top condition too.. Im getting confused to say the least now.. are there any other areas to check?

Also no matter what i do, the little part inside the relay that 'clicks' will not activate.. just thought i would try and explain everything to help in diagnostics..

Cheers!

Pull the relay and check it for continuity between pins 53S-53M (should be 0 ohms if good). If you get no continuity (infinity ohms) the relay is bad. If it's good, plug it back in. If the relay tested bad, leave it out and jumper 53S-53M on the fuse-relay board. The park function should work now. -If it still doesn't, verify that the motors' speeds (both high and low speed) are working (the park function runs through the motors' low-speed, so if low-speed is faulty at the motor, park won't work). Quickest-easiest is to check the speeds by using the wiper switch - all the way up should be high-speed, next position down is low-speed, next is off, lowest position should be intermittant (intermittant and the wipe-wash cycle function also run through the motors' low speed, but they also require a good relay to be in place to work). To test the motor directly at the motor rather than via the switch, look here -
http://www.924board.org/viewtopic.php?t=19033&start=15
Test high and low speed as described there. -Then while you're at it check the 53a pin on the connector (the wire-attached connector) for 12v+ (should be 12v+ whenever the ignition is switched on regardless of the wiper switch's position). 12v+ from that wire is needed to park the wipers.
-Then check for continuity between motor pins 53e(*or "31b", but not "31")-53a (this is the switch inside the motor that operates the park function)- with wipers down in the parked position, you should have no continuity between 53e(or 31b)-53a - with wipers up, there should be continuity between 53e(31b)-53a. Continuity when down at park and/or no-continuity at other positions indicates an internal motor switch problem.

*- that pin will be labelled either "53e" or "31b" in the wiring diagrams depending on model year.

Inside the motor is a switch which is closed if it is not in the park position.
This keeps the motor running until it parks where the switch open circuits.
The wiring to the motor or the motor itself could be faulty.
