I have just replaced my Blower Motor Resistor as my fan wouldn't work on any setting other than 4 (in line with a previous post: How to troubleshoot a fan that won't work unless it's on it's on the highest setting?). When on 4 I noticed a slight squeal but now that it's working on 1, 2 and 3 I notice a big squeal / clunking when the fan is on the lower settings.
Is there anything I can do to fix this or do I need to replace the blower motor?
