Hello, this is my first question I ask here in the forum… I’m trying… I’ve got a Volvo 850, BJ 1996, model year 1997, 106 kW, gasoline. The interior fan recently said goodbye, called the engine ran hot and burned through. I’ve built a new fan, which was running permanently at first, I was able to fix that by replacing the pre-resistance. Now the fan is running as intended, but it is buzzing so strongly at high speed that the total e dashboard vibrates. Did I have another fan sent to me, because I thought that the fan was not well balanced, but the second fan also shows the same phenomenon. I don’t know any advice at all, is it because it is not an original Volvo fan or can something be wrong with the electronics and the fan is controlled with too high a voltage? Enjoy good advice and say thank you
