Hi all,

 

I wasn't surprised when the heater/ blower stopped working recently as I thought it had seemed weaker (at least on the lower settings). The fuse is fine and I stripped the motor out, cleaned it and replaced a broken brush spring while I was at it. A replacement relay #18 made no difference and the reisitor, well what can you do? it looks okay but may not be, so I 'cleaned it up'. It was only after replacing the motor and messed about with the switches that I discovered my heater was actually working, but only on the highest setting. Further investigation on-line turned up a related topic in the Briskoda Fabia section. Apparently if the resistor on a Fabia dies you are left with just the highest blower setting which, unlike theother three is connected directly to the motor.

 

My question to those in the know (and before I splash the cash): Does the Felicia resistor work in the same way so that I can assume a new one will solve the problem?

 

Any help appreciated.

Yes it does, the resistor reduces the voltage to the fan making it slower.

You need a new resistor.. same happend to my air con one after I fitted it in my fun had no engine in bypassed electrics had 2 spare resistors changed that I had all 4 speeds...

There is a big difference between "weaker on slower speeds" and not working at all on slower speeds.

Are you 100% sure the motor brushes or the motor collector ring are not worn out and barely making contact? I had to replace the brushes on my blower after 16 years because it worked only on highest speed,when the current is biggest and somehow overcomes the high resistance of brushes barely touching the copper collector.

 

One other common failure is the connector of resistor box that gets corroded and melts. I doubt very much the resistors are bad. The wire is thick! Have a look at pictures below and judge for yourself.

 

 

 

Update: 

 

A new resistor solved this problem. Before buying the new part I re-checked everything again and was satisfied that all was in good shape. The apparent 'weakness' that I spoke of in my initial post may have been the broken brush holder spring or dirt, then again it could have been my imagination...

 

Thanks to those who responded to my query.

I know this is an old post and a ljg shot. But what is the part number you replaced with because I'm having the same issue? 

That person has not visited the site since 5 March 2017 so might not see your post.  Here are three parts numbers you could research, always treble check the parts as suppliers (and manufacturers) databases, websites and photos have errors and omissions.

• 097 916 018 F
