Up for sale is an Working, in excellent condition Range rover classic Central Locking ECU Relay. This will work in many RRC's with Central Locking. - check the part number off your original to verify for fitment!   Tested, and working, this unit should last you for years. I will warranty this unit to function for 30 days after purchase.  Failures of this unit can occur if you are having problems with a door lock binding.  If the central lock control unit trys to lock a door, but can't for some reason, it will try to lock anyway and these control units can fail before the fuse blows.   

A faulty unit can be noted by central locks that randomly do not work, only work when it's wet, cold humid or when you hit bumps. I have also seen some that just "go off" when ever they please, locking and un-locking the doors when ever they feel like it. You can try re-soldering and repairing your old one, that sometimes works but replacing it with a known good one is a lot less effort. These units now have to be special ordered from most dealers for big $$ if you want a NEW one, and finding one second hand is becoming a chore. Get a good working one here and now for cheap!
