Hi

My first post. (if this isn't the correct place to post, apologies and please advise) 

I've just acquired a 2008 xf 2.7 diesel premium luxury. Love the car but It is an older one so it has its odd issue or 3. The one that I can't make sense of is thus. 

Rear left door won't lock / unlock (with fob or button on dash) locks fine with the manual lever in the door. Also the power window won't work at all. They were fine the day I bought the car but day after. Nada.

The following may be relavant.

There was biblical rain on journey home and I washed the windscreen but had drivers window open slightly. Some water dripped down onto the drivers door control panel. Which I wiped off immediately.

I replaced the jcase 20amp in the drivers footwell that is "rear left door controls". Still nothing

The next logical step in my mind is could it possibly be the door control module. I see there are many on ebay etc but do they need to be programmed to the vehicle (I've only found one post online where the guy claimed it didn't need programming). If it does any idea dealer would charge? 

Apologies for such a long first post. 

 

I suspect it will be the door control module, if they get wet they are tempermental, although if it was you driver window that was open, suprised it would effect the rear, although not sure of the layout of the control units in the jag.

Could be a loose wire going to the control unit too.

Thanks for the reply. Do you think its possible that the water that got in the switches on the drivers door could short the DCM in the rear door? For about £25 that they are on ebay may be worth a punt but can't find any info on whether it would need programming to the vehicle (I'm sure the front ones do but dubious if the rears would).
