Fiesta Diesel Heater plug circuit

[nomininolife]

Hi Guys

I run a Fiesta diesel 1994 MK3 as my daily hack.

I have a problem with the heater plug circuit, the heater plugs themselves are fine, I know this because I link them direct to the battery every morning via a jump lead and it fires up straight away.

My first thoughts were that the problem was with the heater plug relay,

I have tried two different relays, one from a scrap yard and a new sky parts unit but still nothing so I do not believe it was the relay in the first place.

My questions are: a) is there a fuse that could have blown somewhere (I cant find one in the fuse box)?

B) Does anyone else have any experience of this problem?

c) Does anyone have a wiring diagram

Any feedback is gratefully received

Thanks

David

A bit late to reply but might still help, I would assume you should have a fuse somewhere in its own box. ( where, i`m not sure but i used to drive a cavalier diesel and on the bulkhead was one fuse on its own for this ) If this has blown you will probably have a bad earth somewhere so will need to find that, then replace the fuse.

Thanks for the reply, the gearbox chucked the towel in before I could get this sorted so I weighed it in.

Again thanks for the reply.

yw mate, i just joined up yesterday but would have thought the "mods" would at least know about fords or someone would have answered long ago seeing as there are a few who "claim" to be ford mechanics posting here!
