Try the 'search' facility, I'm sure this has been covered before...
can any1 point me in right direction of what fuses to check ? and is it the black block connecter u need to unplug and if i put tester on it what wires do i need to test for power at block thanks
Until Decks comes along, type 'Heater Fan' into the 'Search this Thread' above. There's loads of info there...
Assuming you don't have climate control there's 2 fuses F31 7.5A provides ignition fed supply for the power relay and F8 30A is permanent live to relay T8 on panel B1 to the fan motor N85
If you understand how it works, power is constantly fed with ignition on to heater motor and the fan switch supplies straight earth on setting 4 and through a resistor pack for the other 3 slower settings.
With all 4 settings dead then I'd check both fuses and the relay, then check for power at the fan motor itself
A loss of earth at C16 will give the same symptoms

hi again checked all fuses all ok and power at motor which there wasnt any so read a few posts and checked t8 relay and swapped it bingo faulty relay thanks deckchair for your post much appreciated by me and all on forum for yourtime/knowledge thanks again keith
Right then i was minding my own damn business on friday with the air con on and the fans on '4' all of a sudden all the fans went dead 
I can't use speeds 1, 2, 3 or 4 everything else in the console seems to work fine, its a manual unit with the dials, NOT the auto climate control jobbie.
I've checked T08 (under the battery cover in the bonnet, swapped it with 2 other relays in there all seems ok) and fuse 31 (in the dash) for the 'reverse lights' and fuse 8 (also under the battery cover) still no luck.:bang:
I took the side panel off the tunnel today and had a look round, found a relay up there, dunno what its for. (next to the motor housing but secured on the cage around the steering column i think i was upside down kinda hard to tell)

Whats this brown connector in regards to the scematic?

Also should i be checking here for a feed to my motor? (blue and brown wires in the back of the fan housing, probably a stupid question just don't wanna probe anything I shouldn't)

As you already have side panel removed I'd check for an ign on 12v supply on blue wire at the heater fan. If you have power there then all fuses and relays upstream will be fine
Then it can only be the fan itself, the 4 position fan switch or the switch earth C16
Put an earth on the other heater fan downstream wire and see if the fan starts up with ign on. If fan works then fan is good and it's a switch or earth problem
The brown item is the resistor pack

cheers decks wsill give it a go tomorrow... Trust me you lot will know if it works or not... Is C16 a bulkhead 'bolt on' ground?
C16 is shown here.
turns out its the fan motor lets see how quick fiat get back to me

off to the scrappy i go!
Is there any difference between A/C and non A/C motors?

What are the results of your findings? Is there a circuit through the motor ie not open circuit? Not a simple poor connection at the motor?
Is there power and earth going through the fan? ie is the motor just "stuck"
Have you tried putting power directly on the fan terminals?
Have you thought about fixing your own fan? It's a simple dc motor after all
Is there any difference between A/C and non A/C motors?
The Climate control fan motor has an integral circuit board for fan speed control but that's not to say it couldn't be fitted with some drastic mods like removing the CB to a manual A/C control car. The motor itself may be the same and perhaps could be swopped over?

i ripped the little beastie out yesterday, my god its a tight squeeze! had to remove the UJ off the steering to get it out! anyways twisted arms, carpet burned elbows and a few scratches later...
turns out the braided 'wire' was rubbing against the rotor and finally gave up
so with a bit of solder she was back together:slayer:
into the vice she goes and moments later has 12v rammed up her chuff!
ooohhh look at the prettyness and the windyness and things
well... it lasted barely 3 seconds before it shat itself across the workshop 'HUH... WTF!!!??? ahhh ****e! b******s, F**K!!' :bang:
i think i may have coaxed it a little too enthusiastically from its initial home and cracked one of the fins or rings. soooo im trying to source another.
any tips on getting back in without damaging stuff would be awesome as i have visions of a shard of blade plunging its way through the delicate heater matrix should i be a little too ham fisted upon refitting

Ooo that's nasty
I find tying the clutch pedal down to the horizontal brake bar that traverses the car useful but don't just use weak tie wraps as they will break and the pedal will smack you in the eye. Use some wire cable and tie it securely
If your missus has smaller hands then get her to do it

the problem was getting my 1/4 drive universal join to stop flopping about and actually transfering movement to the screws rather than tying itself in knots lol
the mrs wont touch my fiat... She hates hearing about it and she has my old toyota hehe

went to the scrappy yesterday to get my lovely non damaged fan motor... Had to dig it out of a completely totalled 5door anyway an hour later and shes out and im £25 quid lighter for the priveledge...
Within a half hour i finally have heater fans again it feels like forever when you dont have them!!
Definate word of advice for anyone else is cable tie the clutch pedal back, remove the steering shaft and shove it next to the brake pedal, pop the cover off the pollen filter and take the multi connecter out of the resistor pack it makes removal and refitment one hell of a lot easier!!!
