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.
