Hi Guys
I just wanted to share some information about the heater blower fan problem, i had it for so long and Saxperience was a wealth of knowledge and i hope i am not repeating something someone on here has already put down. But my Dad found this when we were trying to fix my Buttercup, i hope it helps you as it and this website has helped me.
"The blower is in a circuit from the alternator via the ignition switch. It will only work when then ignition is on and the engine is running. this makes some sense as you don't want it sapping power while you're trying to start the car.
If the heater blower stops functioning, the fault is normally with the ignition switch; the thing behind the key. The correct solution is to replace the ignition barrel and switch, which if you have an car is disproportionately expensive, £200 even.
But there is a cheat
there are three circuits run from the ignition switch; the blower-two brown wires and two other(I can't remember the colours. one pair is yellow, maybe?? not important) so it is like three switches in one.
tap into one of the other circuits as follows
remove the cover below the steering wheel (note dip-switch attached to that cover)
Cut the plug from the two brown wires from the blower and strip the exposed ends.Strip rubber from the middle one of the other pairs of wires without cutting.(colours?? yellow and something??)
Buy a free standing relay. Attach that so that when the yellow wires becomes active the relay close. Attach the brown wires so that they are connects together when the relay closes. When you put the cover back, note that the headlight dip switch is still connected to it. It'll fall off while you're working and is easy to forget.
That's it for £5 you get a bit more life out of the ignition switch
an easier way it to the two brown wires, strip them and tie them together but this is rubbish because it means you have to remember to turn the blower off every time you get out of the car or it'll keep running"
That's pretty much it I am not the original author of this information I am just passing it on for others who might be suffering the same problem and want a more long term solution. To the original author if you are reading this, Thank you, your information saved my baby from the scrap yard at the start of winter.
