Door wiring / installing central locking and remote

[madsb]

fix the original pump....
easy to fix... can give you a wiring diagram if you need (email me)....

much better than a solenoid aftermarket solution.

or better still a new pump and a section of the wiring.. I have a feeling the pump has broken (most likely a leaky pump or a split air wire?) and both will drain the battery as the pump will keep running as it can't register the air pressure correctly, and to solve they have chopped the wires rather than investigate a repair

Thank you for the suggestions guys, ill have to consider it.. I'll upload a pic of the wire havoc tomorrow.. Maybe you can make sense of it..

In regards to the original wires in question, I can tell you that the connector with 4 wires is for the central locking mechanism in the door, and the one with the three wires is most likely for heated locks (what the vw dealer said anyway).

Heated locks on a mk3?

Heated locks on a mk3? 

I thought the vw dealer who told me it might be wrong too.. but seems strange that the central locking mechanism should use 7 wires in the driver's door, so they must be for something else. Anyway, I'm gonna install the solenoids.. getting the pump to work again would be a hassle, and I don't know what I might end up breaking, with the existing wire splices and what they do and all.

also it seems to me that the pump system might be more prone to failure that the solenoid one, both due to its age and the technology

i guess vw dealer may have meant heated door mirrors....

My old 2.0 mk3 estate GL spec was a "nordic" edition (i.e. cold weather model) and trust me, that certainly had no heated locks...

pneumatic system is not more prone to error imho..... my 94 mk3 as well as my 96 never had any issues with it.
not saying there aren't any but nothing that can't be solved (often just broken air pipes to corrosion on pump PCB - which in quite a few cases will work fine again after cleaning it with isopropyl alcohol)

Will try to look into if it could be heated mirrors, but I doubt it, since the connector is by the lock..
