Hello. Like the topic states I'm having a strange blower motor issue, at least I assume it's the blower motor. When the car is running we get a nasty humming/vibration sound that comes and goes. When the noise is happening, there is very little air blowing through the vents, regardless of how high the fan speed is set. When the noise/vibration is not happening, the air seems to be pushing through the vents like normal. Earlier tonight we took the kids for one more ride through town to see some christmas lights. While coming down a hill I put the vehicle in neutral and coasted down the hill. While coasting the noise would come and go many times... every few seconds the noise would be happening with no air blowing... and then it would stop and the air would blow hard. over and over.
While sitting parked in a parking lot I also played with it a bit. While the noise/vibration is happening, if I turn the blower speed up or down, there is no change to the sound (as in the fan does not seem to speed up or slow down). When we don't hear the sound the fan is adjusting accordingly with the climate controls.
Possibly related, but wouldn't bet on it, there did almost seem like at times there maybe was a strange voltage issue. Sometimes when coming to a stop it seemed like the noise would fade and go away, and then while starting to accelerate it would come back. Like wise, while coasting down the hill, it almost seemed like while braking the noise would come back, and while not braking it would go away. This wasn't always the case, but it seemed repeatable a few times.
I'm hoping someone has dealt with this issue or can point me in the right direction. It's winter and now that this problem is happening almost always, no heat is going to be a major issue.
Any thoughts?
Thanks in advance.
