Interior heater/AC fan squeak

Does anybody know if the interior cab fan on a 2002 yukon can be serviced i.e. lubricated, to stop a squeak/squeel sound? If so, how do you get at it? Thanks

it sounds like you'll have to replace the fan motor. it's located under the dash on the right side. there is a few screws that hold the lower trim panel on and then a cover over the motor. the motor assy. is not screwed into anything it has a lock tab that needs to be released and the motor will need to be turned by hand about a half turn. the motor will drop right out after the wiring is disconnected. i just did this on my 02, i bought a new fan assy. off e-bay for about $65 shipped. Good luck.
