After noticing a huge animal smell from the truck (I had the vehicle under a car cover for several months) I took off the wipers, pulled the plastic air intake stuff off, found and yanked a "mouse house" from the air/water chamber under the front windshield/inside the top of the engine bay. Followed by a round of Lysol drenching, this cleared 80% of the problem. But I now feel those critters got deeper into the air plumbing than just there at the top (I think they crawled in from the fender drainage area). I need to figure out how to look into the air handlers and see if they built another mess deeper in the vehicle. Are there any dis-assembly instructions for getting to the tubes that deliver air to the dash and heater areas to check? The smell is gettin' mighty bad!
