Hi All,
Has anyone out there had a similar problem to the one I currently have?
Vehicle - 2006 4.2TD 100 series cruiser
Front wipers working correctly on INT & Low speed but not working on Hi speed at all? Washers are working correctly and rear wiper & washers are also working correctly.
I have searched the net & LCool web site but could not locate any info with regards to the wipers not working on Hi speed.
Any help or information would be greatly appreciated.
Many thanks
Howard

Hi Howard,
If they work on Int & Low speed but not on Hi then I would suspect a faulty contact in the control switch. Cleaning it with RP7 or similar may do the trick.
The other possibility may be a connection or wire break going from the switch to the wiper motor. Check harness plugs for dirty or corroded connections.
Cheers
Allan

Hi Allan,
Thanks for info, I have already checked connections etc. to the motor but not the actual switch assembly - will check this when I get a chance.
I was reading on LCool that after you remove the cowling from the steering column that the battery has to be disconnected for 10 minutes or so to prevent the air bags going off? do you know if this is correct? I wouldn't think so but just inquiring.
Thanks again
Howard

Howard,
Certainly there is a risk of activating an airbag when meddling with vehicle wiring. In general, all wiring looms and connectors associated with airbags are coloured bright yellow although the wires within the loom will be individual colours.
The airbag activating power is supported by capacitors which remain charged for up to several minutes after removal of battery power so a waiting time of 10 minutes is recommended.
Be aware though that disconnecting the battery may require you to reset some devices after reconnection.

Provided that you are not fooling with airbag wiring or components I see no need to disconnect the battery if maintaining the wiper controls. However it would be prudent to not place yourself in the path of an activated airbag whilst working on the system and that triggering the system will activate ALL installed airbags simultaneously.
Cheers
Allan

Accessory installers often pick up an IGN controlled 12V from the wiper circuit. Bit of a willd guess, but has anyone been fiddling in that area, especially with Scotchlok connectors ? These are renowned for causing issues.

Thanks Frank,
But no additional electrical work has being done in years to the vehicle, so I'm thinking it may well be something else causing the problem. But a good point to know for future installations.
Cheers

Could be the high speed coil in the controller rheostat has burnt out. Had a similar issue with the int blower fan in a Pathfinder. I would imagine they all work on the same or similar principles.

Hi Malcolm,
No didn't ask for any help on the LCOOL site, but I do find it difficult to navigate the search section to find what I'm looking for - I will try again, and also have a look at the switch contact for the Hi speed when I get a chance, hopefully sometime over the weekend.
Cheers
Howard

Hi Howard
Yes the search isn't entirely intuitive.

You select the forum on the left side (100 series)
In the top bar, enter your search keywords
Click 'search for all terms'
Leave the next window down empty
Click search

Thats should be enough to get you what you want

Thanks to all for replying.
Well it's not the switch unit - have tested this with another working one. Looks like a problem in the wiring loom somewhere?
Further investigation required.
Getting ready for a trip down along the Connie Sue then back to Laverton on the Anne Beadell, so will investigate the problem when I get back home. Who knows the corrugation's might just rectify the problem :)

Cheers

Howard
