hey people , as above really, last time i used the car a cople of months ago they were fine, now when i turn them on nothing happens? checked the fuse's and dosnt seem to be any probs there, whats the next step?

thanks

 

Check for live and earth at the motor itself, then if no joy check for live at the switch, in/out to different speeds, if this checks out ok most likely the resistor pack, especially if full speed still works as this is direct and not through the resistor.

i got a resistor if you need one

 

i got the same prob with my mongayo

 

yours is prob the heater control reisitor or the loom where it joins has also burnt out

aint got a clue about the fiesta though

 

well my blower does either 0 or 4

1,2+3 don't work LOL

 

thats DEFO the heater resistor on either a focus or a mondeo, very comon fault

 

mine STARTED as that, and now dont do anything

give your a few months and will do the same.

blower got noisy as fuck sometimes too.

piece of crap

 

i had this on my mk4 fiesta, changed the heater resistor and everything worked fine. I would suspect this is at fault.

 

if it doesnt work at all it ISNT the resistor, if it was it would only work on full speed..as you have said that it doesnt work at all then start at the motor and work backwards..

 

well mine only worked on 4, then none at all.

so that resistor AND something else fucked?

and where are these bits located?

 

Chris - Where is the resistor located on a mk 4 fiesta then? I'm getting fucked off with either freezing or roasting settings

 

If the motor doesnt work at all on a mk3 its the relay.
You may also find your rad fan also doesnt work which is even more serious.

Find the relay and replace it. Simple job.

Edit: I think its a green one under the fusebox,

 

its a yellow one i think.

 

Where abouts is this on the car as mines fucked too, only got 0 or 4, and how much was the new one?

 

+1

 

Yup that Luke's problem then!!

I love 'net diagnosis Funnily I'll be showing how to PROVE its that later today

Alex

 

Net diagnosis is great.
By the time you get an answer you've already fixed the problem.

Nah, seriously you chaps are all great.
(I'd best be nice whilst still posting questions about my piece of shit escort in the tech section )

 

dunketh, seems you are right fort my temp senser was stopin the fan kicking in , thanks mate, i bet go get some relays !

 

anyone?

 

I changed the resisitor pack on a mates Laguna - it was right by the motor/fan housing itself.
Yes, I know a laguna isnt a fiesta but theres plenty of space where the motor lives so it seems as good a place as any to stick the PCB.

 

anyone!
