Caroline,

From your post I have assumed your fuses are as mine and not John’s piccie.
This being the case then the relays will be behind the dash left of the steering column and a bit awkward to get to.

Dash removal is best and not too difficult but your electrician might like to know about it if unfamiliar with Morgan’s, so here’s a link….

If wired correctly the first two from left are fan low and fan high.

Best of luck

Regards
