Windows Don't Work - 190E G-Reg ::::: Missing Relay

[petemccabe]

Hi,

I have G-reg 190E with windows that don't work (front or back) and I'm trying to track down the problem ...

First thing I notice when I look in fuse box is that there is only one relay - is this right? Seems too few ...? And, if there is one missing, what is the correct part, how do I fit etc?

Failing that I've heard there may be an issue with a diode underneath the fuse box ... mean anything to anyone?

Any help much appreciated,

thanks in advance,

Pete

Did the windows stop working during your ownership or have they not worked since you got the car?

The relay that operates my electric windows a 1986 2.5 diesel is always on when the battery is connected because with the ignition key sitched off, the windows still work.
If you disconnect the + of the battery you should hear a click - the relay goes off. Connect the + again and you hear a click again.
If you do not hear this, it is likely that the relay is not there or that it is out of order.

One thing is certain - if all four do not work it has to do with a supply porblem cause it cannot be that all motors and switches went caput.

So the relay and the fuse are the first things I would check.

On the other hand, could there have been a problem before you bought it in the first place and so they just took off the relay ?

I also need to tell you that unless you know about 12 volt battery circuitry, you should not seek to fix by trial and error - except for replacing fuses with the same rating and putting in a relay if there is'nt one and/or swap with a new one to see if it is the relay itself.

Or else, ask before you do anything as 12 volts circuits use high currents that can burn wires and harnesses - more harm than good sometimes unless you know what yo'r doing.

missing relays

can it be right that I only have one relay?

Also, how should I go about changing the diode, does anyone know?

thanks for the help so far
