Technical Any Idea

[raineuk]

Okay does anyone one have any idea what this is for and is it the correct relay as it doesnt fit any better. Its located in the drivers footwell to the left.

I'm guessing you're like me and just exploring around rather than saying this is faulty?
What I would do is hold the relay in one hand so you can feel when it clicks in and out and then turn on the ignition..........does it click?
Turn on the fan...........does it click?
Turn on the rear heater........does it click?
You get the idea
Eventually you'll find what it does.
As for the fit, if it's nice and tight contact as it goes in it'll be fine, some relays don't always push down snug to the base.
Let me know what you find

I looks like the horn or fog light relay. try to test the horn and the fog light when you unplug it. good luck.
