Hi All;

The fast speed on my wipers doesn't work. After £200 worth of diagnostics at one main dealer it was decided that this was down to the CJB - replacement £1200+. I claimed on my warranty and the company told me to take it to a different main dealer who did their diagnostics - and have just told me that they think it is a broken relay! They ordered a replacement to see if that worked but it was broken when it arrived! So, waiting on another one.

Anyone else experienced anything like this? Why would a static major component which isn't affected by any other moving parts break like this (if in fact it is the CJB)? More worrying is that two main dealers who presumably train mechanics to the same standards and have the same tools available can come to two different conclusions - at my expense..

Pete,

Check out this thread, look at the last post from me

What I recommended to do for troubleshooting is to switch the fuse and the relays

The switching is like for like

If you have a bad relay then switching will restore the fast speed of the wiper and you will no longer have slow speed or something else will stop working like the defroster for the windscreen.

If you look at the diagram under the central junction box lid you can see what the four relays control.


Note: these relays are in the engine compartment not the passenger compartment.

I think that the Land Rover nomenclature is CJB for the box in the engine compartment

Good luck

Paul

Thanks for that

Are you saying the Warranty company TOLD you to go get further diagnostics at YOUR expense with a second full blown LR dealer having used one in the first place ?

If they did I would be putting them into a complaints procedure to be followed up by further actions that may include involving the insurance ombudsman and County Court-ing them.

as the OP has a 2007 car, im guessing its an aftermarket warranty company (like Warranty Wise or Warranty Direct who are both IMO squirming little bag companies)

in which case then the OP would have no choice but to pay for diagnostics up front himself, then if the garage decides it should be covered by warranty they present it to the warranty company. They may then decide to send out their own engineer to inspect or they may just authorise the work if its one of their approved garages.
However if the fault isn't found to be covered by the warranty then the OP is liable for any diagnostic charges plus any repairs himself.
LR do the same for warranty work, they always advise that if its not covered by the warranty you have to pay for the diagnostics yourself. If it is under warranty then there is no charge to you for anything other than a courtesy car maybe.

Sounds like some potentially lazy diagnostics by the dealer to get the car back out the door!

While we are on the subject, this is what the 13MY on-wards CJB (BCM) looks like inside the box

I have played with computers and electronics for most of my life and family members now give me old computers, monitors and TVs etc to try and fix. Most of the faults come down to connector problems, electrolytic capacitors blowing or "dry joints" where the solder has crystallized. This happened in my home printer last week where it just stopped working and I discovered a dry joint in the power supply board. This crystallization process can take 10+ years but with the greater use of surface mounted components on multilayer boards it's getting harder to spot and harder to fix. I gave up on a monitor this week after working for two days on it (I am retired). It had a logic board that was less complex than the one shown in this thread.

I hate to think what modern cars will be like in 20 years time when spares are no longer available. 3 x FL1 2 manual + 1 auto
