I know there is posts about this problem and I am going to clean the fan out. Wasn't sure at first what was causing the noise so removed fuse 9 and the noise stopped. Plugged fuse back in and started again. Right so now I know that it's the fan. Problem is when I plugged fuse back in the fan was still buzzing but now I have absolutely no heating/cooling at all. No lights and no blowers dead but fan is still buzzing. Any ideas please guys???
Thanks in advance
