Here is what happened. My mate came over and dismantled what needed to be dismantled and found the hedgehog he put in wasn't in anymore as it had fallen out, but as it turned out both Hedgehogs are working, we used a multimeter and tested all the wires to the heater motor. Then tried the old fashioned wire direct from the battery to the fan which made it work. My mate the unplugged all the plugs 1 by 1 and cleaned the connectors and put it back together and hey presto, FULLY WORKING AGAIN. YAY.
But not the car is off the road as I popped into town this morning and had to drive back at 15 mph as the car was shaking me to hell, Well yesterday there was an almighty bang, and today my mate got under the car and found the full reason for the play in my steering and the real fault for tramlining. It is the inner track rod end has completely had it. There is soooooooo much play in it. So another friend of mine is Giving me there old Ford Escort 1.8 Ghia to keep. I am not getting rid of my Omega, and will put it back on the road as soon as I can. This has made me very sad as I struggle with manual cars due to my disability but that is life for you!
But a BIG THANK YOU to everyone that helped me on this as I would never have got it sorted without ALL the advice I have been given.
