2016 Seat Leon FR estate 184 diesel heater blower stopped working completely possibly shorting out

[Vwdale91]

Good afternoon all, I am encountering a problem with my heater blower on my 2016 Seat Leon FR 184 diesel ... this is the 2nd one I have fitted now ( valeo and mahle brands) and it had worked for a couple of days and then completely stopped working on all speeds, I'm guessing something is shorting them out, as my friend has tested the power feed harness going to it and it's getting 12v. I'm wondering if there is any common culprits that could cause this shorting out and blowing the motor... As I'm really stressed out with it all now and the bad weather is coming in and really need my blowers working 🙏 is there any fuses or or relays or anything that shares the same circuit ect that could be causing it.... Any pictures and advice is much appreciated Thank you in advance 👍

Both are more than likely Chinese Replacement Auto Parts, the Valeo one I bought last week was and everything I buy from Mahle seems to be chinese. If the power feed is still there and the fan controller has been replaced, then check the condition of the pollen filter and also the air intake in the plen chamber for obstruction such as foliage.
