No fan blower at all...

Xcellor

I have a toyota avensis 2002 and today I noticed my fan blower just stopped working completely. It hasn't worked on the low settings for some years now but on the full setting it would always work.

I had a look at the fuse box and could not see any blown fuses, is there some relay that maybe gone? It's kinda cold not to have any heating at all

Xcellor

I'm thinking the blower motor resistor is the issue...

There were no weird sounds from motor before it stopped working it worked one moment then didn't. Also the fact that it hadn't worked at lower speeds meant it was broken anyway.

Anyone know where the part is? I've taken glove box out and a lower panel and can see the blower motor but so far the resistor is evading me... Looking for something with two philips screws... (according to other cars.. and googling)

Bottom of blower motor screwed into blower motor, it's the piece with the wiring loom attached

Ah ffs spent the whole evening poking around. Right so if I go under the glove box and look skyward at the blower motor I should see it?

Where abouts would one pick up this sort of part? Is online the best bet?

FirefighterT7

Should be there is on 99-00 model and virtually same car.. Yep wiring goes into that it controls fan speed, local motor factors or online Motorfactors.. They shouldn't be very much to buy..

I replaced my blower motor last week on my 2002 Camry. Wasn't all that hard. I took out the glovebox as if I was changing the cabin filter. Since I was there I changed the filter anyway. I had to take off the plastic beside the door in order to drop another piece of plastic so that I could see the three torx screws holding up the fan motor. The motor I got was a cheap one from eBay. Does the exact same job as the original one only a little louder.

5 minute job to change the resistor for the fan

Xcellor

Yeah ive a feeling changing is quick but when you have to find the part first it takes the time. Well ill have a look tomorrow and update thread. Thanks for help.

FirefighterT7

No prob glad I could help..

Xcellor

This is essentially what I am looking at, so I'm assuming its removing those two philips will give access to the part that I suspect is broken?

There is a cable plugged into the socket I've ringed.

Can't see photo but if it where wiring loom is plugged into blower unit, it's the piece loom plugs into remove screws and it should slide out of fan unit.

Mk1 Avensis Resistor is in the drivers footwell, just above the clutch footrest. against the firewall in the middle console.

Perhaps this is why no matter how much poking around I couldnt find it...

I'll see if I can locate it this evening and post a picture just in case anyone else has same issue in future.

Xcellor

Well I located the piece in question and it is without doubt broken. Whether there is something else also broken its hard to know, tried to "fix" it at least temporarily to see if there was any sign of life but

Tried to track down a replacement part today but no joy and a few "ill phone you back" that never materialized....

Having a hard time even finding the part online it has "Welwyn 851081 02 16" written on it . Cant find anything on google for that.

There is no toyota part number which make it a bit annoying

CJhaughey

87138-20340 is the Toyota Part number, the resistor is common though lots of Toyotas use the same part.

Cheers! That's helpful.

I think the fuse maybe blown as well.

Does anyone know if that fuse is located in the fuse box inside the cabin? i.e behind the little coin holder? I checked all the fuses under the hood but I completely forgot about the one inside.

Xcellor

Just ordered from Toyota.. tried several breakers locally and not available so 33 euro + VAT.


Really hope its just this and maybe the fuse that's the problem! Wouldn't want to replace blower unit as well but given that it just stopped working I'm putting my money on resistor and fuse...

Xcellor

When I put the fan onto lowest setting I hear a click from the relay (located behind glove box), also if I press the button to change the change air flow from outside to cabin recirculate I can hear movement.

I'm thinking both of these indicate that there is power but to be honest I'm learning on the job here and this mornings drive into work was not pleasant since I had to have the windows down to stop the glass from fogging up...

I'm just dreading that I change the resistor and I'm still left with no blower. I bought a multimeter today so what I might do this evening is plug everything back together and try testing the power which goes into the blower motor itself, if this is dead then work backwards to the resistor.

*prays for dry evening*

Usually it is the resistor pack I'd say after all few years stuck on full I'd say it finally died. ☺iv to change my own aswell it had the exact same problem as your one. Stuck on full, a cheap fix was to replace the Transistor but I lost a fixing for the pack so I had to replace the whole lot.

Have you checked to see if there is power to the motor?

I only got a multimeter this afternoon. Checked it this evening and to my horror when the fan was turned to max it was reading 12V which meant although the resistor is broken it was still working at max... So I removed the fan unit itself, quite easy to get out considering I had ripped the glove box off already looking for the resistor .

Gave it a bit of a blow... put it back on and wehay its spinning! It's hard to tell if it will last longer than a few days it sounds louder but given that i have all the paneling and the glove box off there is less to insulate it so can't be sure.

But anyway if I can squeeze a few more days will give me time to source a replacement part.

Thanks to everyone who helped. May have taken me a while but I'm sure I've saved the guts of 150-200 euro!

You gave the resistor pack a blow and now the fan is working? It's not good for the fan if it is blowing full speed all the time.

CJhaughey

You can carefully strip the motor and clean the inside of it, mine was well worn but still functional, once cleaned and a bit of light oil on the bearings it was silent even with one blade missing.
Clean all the carbon dust and it will probably run for a long time with a new resistor.

Your resister is gone completely. It is not used on the highest setting this is why it works on 4, its working at full power so no need for the resister to do anything.

It sounds like the brushes are worn in the blower and when you played with it they were able yo make contact again.
Check online to see if the brushes are a serviceable part on your car, if not you should be able to buy a blower from a scrap yard easily enough, depending on how common the problem it.

Sometimes the resister packs can also be fixed for a few pence as its usually a tiny little resister on the top of it thats given in and a new one from maplins can be reattached using small electrical clamps of some sort.

iamtony

Also if the fan is louder or making anykind of a scrapping or grinding noise then the bearing inside it are worn too much and the magnets are pulling the motor to one side. This can also be fixed but at this stage I'd just get a new blower.
