Horn replacement

[mrbhammonds]

There are 2 horns, both now defective located behind front grills . I have located them and unscrewed off the brackets. The electrical connectors are corroded , especially one and i am unsure how they are connected,especially one as it is almost flat. I don`t think they were screwed in and they don`t appear to pull out, any help would be appreciated. (Mercedes C Class (1999)

They look like they should simply pull off the horn unit.

But after 15 years they have corroded and may be stiff to remove. Try some WD40 and leave it overnight to penetrate and then gently work them loose (a small pair of pliers may be required) being careful not to break the connectors off.
