Talk Morgan Forums Morgan Sports Cars Maintenance & Servicing Wiper stalk AR plus 4

Having read all the threads and posts on the subject I'm left baffled as to sources So please double check Paul but my research suggests the wiper stalk assembly fitted to a range of Land Rover's is Lucas STC4016. Click below for source.



The matching light switch is Lucas STC4017 (SQB160) which I have just ordered as a spare as mine can cause intermittency if turned too far.

Prices vary enormously with wiper switch the more expensive but you can buy the pair new for under £100 here delivered.

Note above are switches only not the central indicator self cancelling mechanism.

Yep that is the bit Richard. I have a spare from my old Roadster when the pcb was failing.

Slightly off topic but just found this video on removing stalk light switch on a LR Discovery, as later Mogs use the same Lucas STC4017 (SQB160) switch and I've just bought a spare. Note steering wheel does not need to be removed and imagine there is better access to the two screws that need removing once cowls are off.

Useful part starts 2:20 in. Note the two screws mentioned are supplied fully tightened on replacement switch and after removal and clicking into place need to be fitted through tabs on central plastic moulding before tightening back into new switch body to fully secure.

To get back on topic video on removal of the other wiper stalk switch Lucas STC4016 with upgrade.

Thanks Richard, although the cut off screwdriver is a bit bodgetastic , just use a pozi bit out of a power driver and a small ratchet ring spanner

Agreed Jon, good engineering practice and video making don't seem to go hand in hand. Sometimes better than the "here's one I made earlier" style though where the job shown takes seconds compared with hours in practice.

I was amused by the captioned "this bit was fiddly" in second video by contrast.

Gentlemen, thank you all for your contributions, it has certainly given me a few thoughts and ideas to work on. Hopefully I will find the right part and can get back to this topic with my findings, which might also help others.

I've named him the 'Barnsley Bodger' after watching him attack clips with a Stanley knife, and stab elec connectors with a large pozi driver, he should stick to creasoting sheds !

Paul although the ARP4 had a plethora of differences with mainstream Classic production, I cannot for the life of me see why MMC would have departed from adoption of the normal readily available stalk switches given they look identical. The outlay and time in developing differing wiper control just for the sake of offering something different wouldn't have made economic sense.

Having taken the opportunity recently to delve into the above mentioned Lucas STC4016 (see above for source) wiper stalk application I can say that it's heavily integrated with the six pin WEHRLE 60 201 002 wiper relay as shown below to implement the single wipes, wash wipe and delay functions available on the switch as well as constant two speeds.





Presence of this on your car would be further confirmation although there are alternatives seemingly offering the same functions.

Look forward to hearing your updates.

Time for an update on my wiper problem.

It is actually going to be a bit of an anti-climax I'm afraid, as it turned out to be nothing more than a loose plug which just needed pushing back on firmly, having done that, everything was back to normal.

I may actually look for another wiper stalk assembly, as I am using a 13" steering wheel, which is perfect with the electric power steering and means I can see all the dash board as well as the rev counter up to 8000 and the red light, but the stalks stick out a little too far beyond the wheel rim to be comfortable, so everyones kind suggestions may not be in vain.

Thank you all again for your interest and ideas.
