Question Newbie needs help PLEASE

2006 sentra se r

1. when I turn on ac or heat sometimes I hear what sounds like a squealing noise and also sounds like something maybe in fan and as soon as it's turned off noise stops.

2. the motor started making a funny light sound I can't describe and when the lights are on it looks like they may get dimmer and then brighter. I don't know if it's other lights are making it look like that or what.

If anyone has any suggestions or ideas I'd greatly appreciate your help.

The fan motor may be worn or there may be some debris around the fan blades. Is the noise present at all blower speeds and does it change in intensity according to the speed setting? Removing the fan assembly is a major effort; a good part if the dash needs to be removed.

KA-T for life, yo!
