I recently changed the cabin filter in my car. Having never done so in my Silverado, I started researching it. Finding nothing on that subject on-line, I called the local dealership: the 2011 Silverad...
I changed the one in my 2002 Silverado for the first time tonight. The fan was blowing kinda weak, so I figured after 17 years and231k miles it was time. The air blows much harder now.
