How do you change the pollen filter on a Cadillac CTS?

Answer 1

Open hood. Remove weathstrip at the wiper cowl,starting at the passenger corner, near the windshield. You'll only need to remove it halfway, should come right off. There are 3 small screws along the plastic cover. They are 7 mm. Remove them. Remove the black plastic piece. Stick both hands into this open area, which you can't see down. Feel for the sides of the plastic lid and you should feel two tabs, Pry them out and up to remove the lid. Wiggle the cover out of the hole, but remember how it came out. Now reach back in, and remove the filter, which will need to be squeezed together, again remember how it came out. Take new filter, look for an arrow, some have it some don't. That points towards the cabin. Put filter in same way came out, might have to squeeze together like an accordian and you'll have to angle the bottom of it towards the back of the car to seat it in it's channell. You'll now when its in caused it should stay flush with the plastic tabs on the top. Put lid back on, making sure it snaps on, put plastic cover and screws back in,and weatherstrip. Good luck in can be a challenge since you can't really see down there.
