My W126 (1988) has been setting quite a bit lately, but I have been starting it and letting it run for about 10-15 minutes per week and moving it about the driveway, but on Sunday afternoon I turned on the HVAC and the blower has started squeaking. It does not squeak at first, but after a few seconds, it will start to squeal and sounds like it slows down.

Is there a repair procedure by lubing the wheel or motor or does something have to be replaced?

Thanks.
