92 400E Noisy Blower Fan ??
I recently noticed what sounds like a noisy fan motor coming from the general direction of the passenger side A/C vent. The sound is sometimes a high-pitched squealing noise and at other times a low-pitched churning noise. I am assuming this must be the blower fan.
What seems strange is that I hear the noise even when the Climate Control System is in the OFF position. Does/should the blower fan run even when the Climate Control system is turned off ? If not, does anyone have an idea of what/where this noise may be coming from ? Thanks in advance for any help....... |

I believe there is a small recirculating fan behind the passenger-side dash that could make this noise.

Aha ! I sort of expected as much, since I noticed that when I activated the Climate Control System fan that the noise was not affected.
Anyone know if this is a DIY'er repair or replacement and how to get started ? Thanks, RM92400e |

If indeed this recirculation fan exists, is there anyone who could provide information on how to get to this thing ?
This noise is driving me bonkers.... Thanks, Ray |

Try this one:

Thanks Carman850, but....
as I said in my original post, this problem does not appear to be related to the Climate Control System blower fan that your URL link refers to. The problem occurs when the Climate Control System is in the OFF position. I even tried turning the CCS on and off when the problem occurs. Doing this has no affect on the problem, so that leads me to believe that the blower fan is not where the noise is coming from. Still looking for help..... Thanks, Ray |

You need to remove the lower dash panel on the right side to access the recirculation fan.
