92 740 Turbo Wagon Central Locking

Dalpatine · Post by **Dalpatine** » 24 Mar 2015, 18:03

All,

I have a new to me 92 740 turbo wagon that has been garage kept and is in fantastic shape. (He bought it in 2010 with under 60,000 miles on it) it now has around 100,000. The previous owner said recently that within the last month the central locking stopped working. I can unlock each door individually and it doesn't seem to be an issue with the actual locks themselves. But I could be wrong.

I am able to live with this, but I would like to see if there might be any ideas on what could be fixed. Could it be a relay? If so which one? I have seen multiple relay diagrams on the interwebs and they all seem to show either K or L as the central locking relay.

Or is it something else entirely? Any help would be much appreciated!

Thanks, the hazard flashers work fine. So I don't think it has to do with the fuses. I have a replacement relay on the way to see if that could be causing the problem.

If I get too impatient waiting on it to arrive I also have a 93 940, if I am correct the central locking relay are the same on both. Could I test my theory by swapping them out?
