1977 w123 intermittent wiper

[Foxglove]

The intermittent wiper function just stopped on the 280CE . The rest of the switch works fine , that is normal and fast speeds .



I saw an intermittent wiper relay on ebay . But I cannot find it in the car ??



Can some one please help me find the wiper relay in the car .



I have the under dash panels off and can see no relays .

I have lifted the cover on the right inner guard , there are 5 relays there , none have the same looks or number as the ebay relay .



OR maybe it is just a switch issue ??



Thanks for your thoughts .
