Glad to know that you have finally located it. I would be tempted to test the unit first, but since they are very cheap anyway, it doesn't harm too much order a new one. It doesn't have to be a genuine part, your local motor spares shop could probably sell you something suitable. The A post is the post that the front door is attached to.
OK, you have found the big obvious one, with a multiplug on it. The one for the turn signals it is a little further in, i mean towards the engine, but it is significantly smaller. I have just looked in my car and i understand that it is not very visible. It has its back (i.e. opposite to the spade connectors side) resting on the A post, while 2 wires should be connected to it.
Hi Demitris, the flasher unit was right were you said it would be! I unpluggged it and of course the emergency flasher became inoperable. I realized I meant the turn signal flasher unit. Are they one and the same or is it true there is a second one behind the instrument panel? Geez, two flasher units, what next?! I have one on order but fear it won't help my turn signals not working.
Thanks for your kind advice.
