Ive got a 2009 Audi A4 B8 with 120k miles ish. Ive got a issue with the blower motor. I got the car in august and in the mornings it blew and i had no issues, when i was driving Home after work no air was coming from the vents. I had no issue with that, i just rolled the Windows down. Its been working past 2 months without issues but now its freaking snow and cold as heck here in norway and today the blower worked just fine in the morning and on the way home. But when i was going to the gym it didnt blow, no air coming out. But after i finished and was going home it worked again. So annoying when its cold outside. I went to the shop later and i didnt work again But on the way home it started working again after 3 minutes. Does anyone have any idea what i should check or look at? Or should i just replace the blower motor?
