interior heating blower fan not working but fuse is fine?

Access

Hi,

My sis has a ford escort...

The interior heating blower fan has stopped working and on checking the fuse board, the corresponding fuse is fine, (checked visually and tested with continuity on a handheld meter) and i also took out the fan speed selector switch in the dash and the continuity is working fine on blower fan speed settings 1,2 and 3.

According to the manual, there is no relay to control the fan, so it cant be a relay.

Im stumped.

I would love to get it working again as she is having a long and cold commute to work at the moment!

Any Ideas?

Any access to the heater blower from the bonnet side? sometimes you can get a hand in through the air intake , give it a spin see what happens.
From what you say the motor maight be gone.

Rather not rip out the whole dash until im sure its not a hidden relay or resistor or the like.

The fan was fine up till last week she was saying. she went out to the car one morning and it just didnt respond to the fan speed switch... no fan grinding or loud noise or the like.

Will try access the fan from the bonnet side to see if all is turning fine when i see her tomorrow.

There must be some resistor or relay somewhere to regulate the speed that im missing?

You need one of these



Fan speed resistor. I don't know where its located but I hope this diagram helps

If it was the resistor pack it usually always works on the highest setting...I'd say your motor has siezed or its a relay...ill check where the relay is tomorrow if I remember...what year is it?

I'm willing to bet its the motor too. Had to replace one on the OH's focus there a while back too. See if you can spin it freely by hand without any resistance, if you can't there be the problem.

Its '01... last of the escorts made.

Thanks for that... cant access the fan motor at the moment... so i would like to check any resistor pack or hidden relays first.

Do you have power at the switch?

If yes, try to check for power reaching the motor

If No, I'd suspect the distribution unit (fusebox thing) they were notorious.

If you have power reaching the motor but no action then its most prolly the motor.

Check this relay in the engine bay...i think its for AC/and the blower its the one ive marked in red...

If all that is ok...id be checking to see if the motor is turning...if you need parts i should have some aswell

No such relay in the engine bay for the blower fan im afraid! -

Whats my last options before i send my sisters car into my local mechanic?

Would the blower motor be accesible from the engine bay or under the dash in this escort?

Might try to see if it is rotating by hand and will give it 12v it see if it is the blower fan.

+1. Fusebox itself was notorious for giving this trouble on earlier 93/94 Escorts, not sure about the later ones.

If it is the fusebox itself, I may have one. I recently scrapped a 97 escort ghia, pm me if you need it.

the fan resister is located under bonnet at the bottom of the windscreen, roughly in the middle of the access area. it may not be gone if all fan speeds are not working but because of its location is prone to getting damp from rain, and if you open the bonnet on a rainy day all the water just flows back on top of it, there is a small cover over it(badly made). lift off the cover and rattle it a bit and maybe remove and check connections. if all is ok there and all fuses are good then motor is blown.
