Fan Working on Full Blast But Not Lower

(1/1)

Hi guys.
Ive had a search of the forums, but cant find the same issue....well not exactly the same anyway.

My son turned 17 and we got his car a few weeks ago.  Its a 1.2 Polo 2017.

The problem is with the fan....same issue regardless of direction.  If you have the fan on the first 3 levels it doesnt blow at all, however the highest setting of 4 works perfectly. 

As sure as I possibly can be, theres nothing at all coming out on 1,2 or 3.  Ive switched the engine off and listened carefully, but it sounds totally dead on those settings. Comparing it to me vw EOS, id say 4 is perfect, and as powerful as you would expect.

Does anyone know the possible cause...its almost like the first trhee settings are on a seperate fuse?

Thank you.

Those symptoms usually mean that the fan blower resistor has failed. The resistor is used in the lower speeds to slow the fan but not used at the top speed hence your symptoms.

Yep , fan resistor failure
