Hi all,
Rear wiper was working very slow and it stopped completely in the middle. Following day morning noticed that the battery was half dead and thought that wiper 'auto parking' was trying to get it parked , hence the battery drain. Removed fuse 15 & charged the battery no more battery draining. With fuse 15 gone, no interior lights & rear lower door lock functions. However, noticed that whenever I open a door the interior lights come on, momentarily. How can this be, as the fuse-15 is the sole power supplier to interior lights / rear wiper circuit?
Could not check the connections at rear wiper , yet.
your advise is appreciated, as this could be the culprit on my battery drain.
 
Just a suggestion disconnect rear wiper completely, re fit fuse, see what happens, if all ok it sounds like the wiper motor fubar
 
Done but it drains the battery. Must be something with the interior light circuit.

Sounds like it is earthing somewhere else.

My rear nearside passenger interior light hasn't worked in ages. Fuse fine and bulb and indeed the light unit. So must be a wire or connector gone somewhere. No battery drain though and wiper works fine.
 
Even after I remove the fuse 15, the interior lights blip momentarily whenever I open a door.
Means that it's getting power from something else.:confused:

I need to check the wiring diagram but I suspect it is permanently live and earths in order to come on. If so, it is finding an earth somewhere which with you opening the door might be a chafed wire or similar.
 
When my front windscreen wiper motor was faulty it caused all sorts of electrical error messages on dash display and strange wiper behaviour

Lamps/wiper are switched and controlled by BECM. I would think the fault is with the wiper motor.

Though I disconnected the wiring connector, did not check the motor with a direct supply. will do that n see. Is the wiper motor repairable?
