Is this Hissing normal when the heater is on?? Blower settings 1 or 2 Max heat. Sounds like the same Hissing when I had the Air on this summer. Build date 10/04.
Wrong! It may be the blower motor. I took mine in last week for a hissing sound and they found an air leak at the blower motor housing. They resealed the housing and I haven't heard a peep since.
To be sure I wasn't just being picky I sat in a new Titan on the lot and had a salesman start it up so I could listen to the vent system before I made an appointment. The difference was clear.
