Hello, I just recently got a problem with my blowermotor in my 2014 E200 S212 Facelift.
It started with the blowermotor stop working in the middle of the drive and it could just start up again randomly, after awhile it completly shut off and couldn't get it to work again.
I bought a new blowermotor and a new regulator, and now the new fan works on all speeds but it shuts off in about 20 sec and then turns back on again after 2-5 sec and it just repeats the process all over.

Does anyone here know what could cause this or what I could try to look into?
I also diagnosed the car and it seems like there is no fault-codes that would explain the problem I am experiencing

Thanks
