Has anyone had experience of more than one resistor pack failing on them in a short space of time? My original one died in January leaving the blowers stuck on maximum, so I sourced a 2nd hand replacement off of here which worked fine but also suddenly died on me y'day, causing same symptoms (full blowers). Now I know it could be coincidence, and that it was a 2nd hand part that was fitted, but starting to think there is probably an underlying problem. Pollen filter was changed last month, and all seemed clean in there, could I possibly be looking at a failing fan motor causing it? Although the fan does seem to run ok when not stuck on full power, only thing iv noticed is an occasional squeak from vent areas. If anyone can share any experience or any ideas of where to look would be much appreciated, ta!
