Thread: xyz refurb long lasting?

Hi, if your onto your 3rd one already, then maybe time to address the problem of what might be causing theses switches to fail. Have you re-routed the drain hose from the A/C that drips water all over the xyz switch?

Re-routed the drain after the 1st failure. On taking the 2nd failed switch apart there was no sign of water entry and I understand that is what others with the newer style switch have found, water has not caused the problem. There is just one of the sliding contacts covered with dark gunk ( I suspect its the one for reverse). The stuff seems to be some of the electrical grease in the switch which has "gone bad". The question is why and the only answer I can come up with is overheating, perhaps thru bad design. If that's the cause then cleaning it up would not stop it overheating again---hence my Q in my 1st post.

There is a guy in Melb (David) that overhauls these & from memory offers a 12 Month warranty.

He is also the guy that does LED modules, a electronic's engineer from memory
Has done a few for us & have not had any complaints yet!!

Send him an email & he may be able to help i suppose.

Cheers

Looks like I'm going to answer my own question. I have cleaned up what appeared to be the one contaminated contact and rebolted together and refitted the switch yesterday. Very early days but its working fine so far.
My switch is the later version with sliding contacts. Once opened its easy to see how it all works and if there is anything obviously wrong. Its also easy to check all the contacts with a multimeter even by a electrical dummy like me. The older versions are a different ball game.
I first thought the contamination spot was a result of overheating but now I think its a result of the surface of the guilty sliding contact rubbing off and mixing with the electrical contact grease in the switch.
Thanks to sniegy I followed up the professional refurb info. Linear Electrical Design in Melbourne do a detailed recondition of the switches--cost is $360 with a 1 year guarantee. They say they are doing them for LR dealers and have not had a switch returned. Not cheap but half the cost on a new switch. I don't know if they do the older versions of the switch. They only accept switches that have not been opened.
Cheers

Raising this again as I have just come back from a 13,000K trip towing a caravan around WA. My self repaired xyz switch operated trouble free and is still working normally. The repair just involved cleaning off some obvious gunk on one of the sliding contacts--cost me nothing except some of my time. A new switch plus installation, especially 'thru a dealer would be around $1000. Have now been told the gunk was probably a mixture of the original switch electrical grease and surface plating that has, with use, rubbed off the contact track. Anyone having the flashing M&S lights/limp home syndrome from the later sliding contact type switch be aware the fix may involve no more than cleaning the fouled contact.

With the newer design of the switch the failure appears to be related to burning or arcing of the spot contact for the reverse position. This isn't a sliding contact and doesn't appear to be self-cleaning. The contact is held above the slider on a rail and only drops down on one position.

My genuine replacement cost £208 from Ashgrove Transmissions in the UK in late September (Landed price) which I think is much better value than $360 for a reconditioned switch. I've cleaned my old switch and will keep it for emergencies.

I found switch failure to be a nuisance as it only occurred when using reverse, it just means you have to restart the vehicle after reversing to reset the warning lights.

Is that Ashgrove or Ashcroft?

Use this kind of stuff on the switch, i used it all over the car on all ECUs/BCU, fuseboxes and exposed connectors too, migt be a placebo but it seemed to run better after that...they must have a dealer down under
