Rear wash wipe switch C220

[Pipemaster]

The rear wash wipe switch on my wife's estate works fine for a while (intermittenetly) but then becomes continuous and you cant switch it off until you turn the engine off for a while. Is this probably a sticking relay or something else?

Does anyone know where it is?

There is a relay fitted next to the motor itself. You could have a leaking washer pipe at the motor causing relay problems.

Could be the relay, does it sometimes trigger off when in reverse?

yup

Could be the relay, does it sometimes trigger off when in reverse?

it does trigger when in reverse I thought that was a feature? !

Yeh, it's supposed to.

thank God for that! So it could be a sticky relay then as it is OK for short bursts...
