You ain't just whistlin' Trixie...

Actually I'm kinda hopeful that's all it is. Trixie has developed a strange whistle. It's intermittent and doesn't seem to be causing an issue. I am wondering if it's just that her front bumper needs to be replaced. After driving back from a trip to the mountains we've learned that her headlights need to be adjusted a bit too. I guess the new bumpers are getting moved up on the list... I need an oil change, again, wish that was a once & done thing. It seems like the blower motor has stopped working too. We have heat/AC but with nothing to blow it into the car, it doesn't really work, unless you're driving really fast down the highway. Like over 80... not that we'd ever do that. :-D  So my dear amazing wonderful boyfriend is going to look at the information I've collected online & decide if this is something he'll attempt to replace or if we take Trixie into see Garrett Automotive.  What do you think? Would you attempt to replace the blower motor yourself or take your car into a shop?
