Cabin air filter...
#12
Well, after 18 Months and 9125 Miles I thought I'd better change the cabin air filter. Yipe!! What a mess I didn't think it would collect that much crud. Guess I'd better make the change at 12 Months from now on.

I heard on another thread that every 6 months might be a good idea. I am big on clean air....I will check mine in a couple weeks (3 month mark). With all the pollen and dust in our air around here, I think it might be best.

According to my GMLink site they recommend the cabin air filter be changed every Maintenance II that is done. That equates to every other oil change..
