Yellow relays used on about every ford and every car std DIN pin layout as well.
Got at least forty in my spares box, (must clear out).
Same as the advertised "rare" relays the little ones for mondeos to work indicators for alarm on early ones they are common bit on most cars.
The relays for the fan on mine had a fuse on it in a little holder, but It would be worth trying the above ie pull the relays to see if one duff in the fuse box as yours might be wired the same as theirs and have relay in fuse box, mine is not but seemingly some are, good old ford.
Would be a lot easier than pulling lower dash out to start with.
