Mk1 Gs300 Wipers Question

[TCUK]

Recently when I start up my Mk1 GS the wipers move from retracted position hidden under the lip of the hood to standard position for a few swishes then this stops is this a sign of a problem? I am not using the wipers at the time and I know about the switch on the stalk. Its like they are just moving up and down 3-4 inches then stopping on startup after a couple of seconds. I am assuming it is some kind of signal fpor a fault. They work perfectly and are not sticking. Anyideas anyone? Its bugging me.

Very odd,was the wipers on the night before? my first point of call would be the relay,cheepest and fastest thing to change.

Wipers not on the night before may be a relay otherwise it seems like a mystery. Anyone else know what this issue is?

This is the system overview from my manual. Maybe it might help trace what might be causing the problem

1. LOW SPEED POSITION

WIPER SW AT LOW OR INT POSITION

WHEN THE WIPER AND WASHER SW ARE AT LOW POSITION, A SIGNAL IS OUTPUT FROM TERMINAL (A)11 OF THE WIPER SW TO TERMINAL 13 OF THE WIPER RELAY. THIS SIGNAL ACTIVATES THE WIPER RELAY SO THAT CURRENT FLOWS FROM THE WIPER FUSE TO TERMINAL 8 OF WIPER RELAY " TERMINAL 16 " TERMINAL 5 OF WIPER ANGLE CONTROL MOTOR " TERMINAL 6 "

TERMINAL 6 OF WIPER RELAY " TERMINAL 15 " GROUND, ACTIVATING THE WIPER ANGLE CONTROL MOTOR SO THAT THE

WIPERS OPERATE AT LOW SPEED WITH THE WIPER ARMS AT THE RAISED POSITION.

WIPER SW AT HIGH POSITION

WHEN THE WIPER AND WASHER SW ARE AT HIGH POSITION, A SIGNAL IS OUTPUT FROM TERMINAL (A)11,. (A)12 OF THE WIPER SW TO TERMINAL 13, 3 OF THE WIPER RELAY. THIS SIGNAL ACTIVATES THE WIPER RELAY SO THAT CURRENT FLOWS THE SAME AS WHEN THE WIPER SW IS AT LOW OR INT POSITION, THUS ACTIVATING THE WIPER ANGLE CONTROL MOTOR. AS A RESULT, THE WIPERS OPERATE AT HIGH SPEED WITH THE WIPER ARMS AT THE RAISED POSITION. THE RETURN POSITION OF THE WIPER BLADES IS ALSO AUTOMATICALLY ADJUSTED TO A DIFFERENT POSITION TO LOW SPEED OR INT OPERATION TO PREVENT

OVERRUN.

2. LOW SPEED OPERATION

WHEN THE WIPER SW IS AT LOW POSITION, THE WIPER ANGLE CONTROL MOTOR SETS THE WIPER ARMS AT THE RAISED

POSITION. AT THE SAME TIME, CURRENT FROM THE WIPER FUSE FLOWS TO TERMINAL (A)14 OF WIPER AND WASHER SW "

TERMINAL (B )1 " TERMINAL 3 OF WIPER MOTOR " TERMINAL 1 " GROUND, OPERATING THE WIPER MOTOR AT LOW SPEED.

3. INT POSITION

WHEN THE WIPER SW IS AT HIGH POSITION, CURRENT FROM THE WIPER FUSE FLOWS TO TERMINAL (A)14 OF WIPER AND

WASHER SW " TERMINAL (A)7 " TERMINAL 2 OF WIPER MOTOR " TERMINAL 1 " GROUND, OPERATING THE WIPER MOTOR AT

HIGH SPEED. AT THE SAME TIME, THE WIPER ARNGLIE CONTROL MOTOR SETS THE WIPER ARMS TO RAISE POSITION AND

AUTOMATICALLY CHANGES THE RETURN POSITION OF THE WIPER BLADES TO PREVENT OVERRUN.

4. MIST POSITION

WHEN THE WIPER SW IS AT INT POSITION. THE WIPER ANGLE CONTROL MOTOR SETS THE WIPER ARM TO RAISED POSITION. AT THE SAME TIME. A SIGNAL IS OUTPUT FROM TERMINAL (A)5 OF THE WIPER AND WASHER SW TO TERMINAL 10 OF THE WIPER RELAY. THIS SIGNAL ACTIVATES THE WIPER RELAY, AND FOR 0.6 TO 1.0 SECOND. CURRENT FROM THE WIPER FUSE FLOWS TO TERMINAL 8 OF THE WIPER RELAY " TERMINAL 4 " TERMINAL 3 OF WIPER MOTOR " TERMINAL 1 TO GROUND, ACTIVATING THE WIPER MOTOR. THEN APPROX 2 SECONDS TO 10 SECONDS AFTER WIPER OPERATION STOPS, CURRENT AGAIN FLOWS FROM TERMINAL 8 OF THE WIPER RELAY TO TERMINAL 4. ACTIVATING THE WIPER MOTOR. THIS OPERATION REPEATS WHILE THE WIPER SW IS AT INT POSITION. THE TIME INTERVAL BETWEEN WIPER OPERNTION CAN BE ADJUSTED USING THE INT TIME CONTROL SW.

5. FULLY–CONCEALED/SEMICONCEALED CHANGEROVER OPERATION

WHEN THE FULLY–CONCEALED/SEMI–CONCEALED CHANGEOVER OPERATION SWITCH IS CHANGED FROM FULL TO SEMI, A

SIGNAL IS OUTPUT FROM TERMINAL (A)11 OF THE WIPER AND WASHER SW TO TERMINAL 13 OF THE WIPER RELAY. THIS SIGNAL ACTIVATES THE WIPER RELAY SO THAT CURRENT FLOWS THE SAME ROUTE AS WHEN THE WIPER SW IS AT LOW OR INT POSITION. AS A RESULT, THE WIPER ANGLE CONTROL MOTOR OPERATES AND MOVES THE WIPER ARMS TO THE RAISED POSITION. WHEN THE CHANGEOVER SW IS SWITCHED FROM SEMI TO FULL, A SIGNAL IS OUTPUT FROM TERMINAL (A)11 OF THE WIPER AND WASHER SW TO TERMINAL 13 OF THE WIPER RELAY. THIS SIGNAL ACTIVATES THE WIPER RELAY SO THAT CURRENT FLOWS FROM THE WIPER FUSE TO TERMINAL 8 OF THE WIPER RELAY " TERMINAL 6 " TERMINAL 6 OF WIPER ANGLE CONTROL MOTOR " TERMINAL 5 " TERMINAL 16 OF WIPER RELAY " GROUND. THIS ACTIVATES THE WIPER ANGLE CONTROL MOTOR SO THAT THE WIPER ARM MOVES FROM THE RAISED POSITION TO THE STORED POSITION.

6. WASHER CONTINUOUS OPERATION WHEN THE WASHER SW I.S ON, CURRENT FROM THE WIPER FUSE FLOWS TO TERMINAL 2 OF THE WASHER MOTOR " TERMINAL 1 " GROUND, ACTIVATING THE WASHER MOTOR TO SPRAY WASHER FLUID ON THE WINDSHIELD. AT THE SAME TIME. A SIGNAL IS INPUT TO TERMINAL 11 OF THE WIPER RELAY, ACTIVATING THE WIPER RELAY AND RAISING THE WIPER ARM. CURRENT FLOWS FROM THE WIPER FUSE TO TERMINAL 8 " TERMINAL 4 " TERMINAL 3 OF WIPER MOTOR " GROUND.
