Driving Light and Noise from Steering Column

About four months ago my left turn signal went out, after I replaced it, I noticed that the light blinks when I engage my turn signal, but when I turn my lights on, it stays dark (as opposed to turning on dimmed). I was wondering if you think it is a problem with the bulb, or an electrical problem.

Also,

When turning while my Jeep is still cold the steering column makes a loud squeeling noise. Any thoughts on what might be the problem?

My steering column makes that noise cold too. I think it is just the plastic on the column rubbing, but I havent figured it out for sure.
