Air blower, dead battery

What is the simplest way to lubricate a squeeky fan.

Sorry to say but u will need to replace fan motor very soon, that is the first sign of wear, also check if u have water coming in on passenger side foot well area, if u do check cabin filter housing seal. To test for water leak run your garden hose on passenger side windshield glass then check flooring, reason been water may be getting into your fan motor & in turn causing fan to squeak.I should have ask this is this car a new style 9-3ss, cause this repair check only refer to that body style.
