On my 2006 Trailblazer LS, I have an electric Moonroof, which puts up maybe 2" or it fully retracts. I have never owner a vehicle with an elec. Moonroof before. My question is, how well do the air deflectors work and what purpose do the serve? I am looking at purchasing one from a reputable manufacturer (Lund, GTS, etc). I purchased my Trailblazer late fall, so did not have a lot of time to really use the moonroof, before the colder New England weather set in. Just trying to get some input on pro and cons for the product listed above. Thanks, Jim

 

By what I read, where my TB has OnStar, the wind deflectors for the sunroof will not fit, due to the OnStar receiver/transmitter being in the way.
