hi all im new to this forum

... i own a mk2 fiesta xr2 1989 its been a really good fun car so far but the other day i went out to start the car and the window wipers,rear heated window,in car heaters all werent working ive checked all fuses and they are ok

any help would be brilliant cheers ive tryed the releys on the top i took them out then put them back in and everything worked but when i switched the car off again then back on the problem came back do you think that is signs of a dodgey relay or something more serious like new fuse box ect thanks
