My A/C and Heater fan makes noise when i turn it to higher speed. I have detected where the blower is wish to replace it . It is supposed to have three gold screews. Two of them i can easily access. The third one i can't spot it .It seem to be hidden behind a lot of wires. Could some please guide me as how i can remove that screew and the fan assembly.

Thanks in advance...

 

If you see 2 screws, the third would be equal distant between them on the circumference.

The blower motor housing is round, the screws are on the outer circumference of the housing.

Once the screws are removed the blower assy will drop down.
