Last night I started hearing a motor noise to the left of the steering column behind where the A/C sensor is. It sounds very similar to the motor for the tilt / telescope, but does go off with the key. Any ideas?
Look for threads in here, Deville and Cadillac Tech Tips on the "aspirator" - the module behind that little 1" square grille, left of the steering column. It's a computer fan assisted sensor for cabin air temperature.
You can lube the muffin fan hub - Stick a finger in the rubber grommet in the dash end (the window vent tube) and yank off the end of the dash. Pull out the plastic vent tube. Straight in there's a small hex head sheet metal screw. Loosen it, remove with spring mechanic's fingers. Snake out the connector, unplug and fish out the sensor module. There's a sticker over the fan hub/axle. Put a drop of synthetic motor oil on the axle, diddle the fan and replace the sticker. Blow out the tunnel with computer compressed air. Reassemble.
Somewhere in Tech Tips there's a series of pictures on this.
