2015 Ram 1500 Sport chirping noise

[W_Black]

Hello, I have a 2015 Ram 1500 Sport 5.7 hemi. Crew Cab. I've had it for over a year, and it drives beautiful. Excellent ride, and power. About a month ago I started hearing a chirp sound from under the hood. We checked it out, thought it could be the belt. So we replaced it. Same thing. Checked the pulley(s). Changed the idler first , then later the tensioner. Same chirp. Checked the other pulleys (water pump, power steering) everything good. Then we realized the sound was coming from underneath. Right where the two doors (front and rear) meet. The funny thing is... No chirping during startup. The sound doesn't come until 45-50 minutes later. Then you hear it at idle, and while driving. No grinding noise, just annoying, steady chirping. Cany anyone help? Much appreciated.
