Ok panic time

Sods law driving to Buxton on 26th went to the shop this morning wipers aren't working head in a spin

Done battery reset nothing
changed relays and fuse nothing

Where next please don't tell me I'm gonnahave to strip everything down

Switched out the stalk no change

Probed power to the wiper motor that's working

Probe showing voltage at relay terminals also

Just hooked up to toaf

Cleared codes

Then moved wiper stalk got the following

8c front wiper enable output
96 front wiper stalled
94 front wiper feedback signal

If there's power at the motor then I'd say it would have to be the motor itself?

Daz,

Remove the wiper motor connector and place your voltmeter's red probe on the loom pin 3 (RLG wire) and the black probe to earth. Turn on the ignition and select slow speed wipers. Do you see +12v?

I have seen some where a broken wire between the underbonnet fusebox and the wiper motor causes this.
