I purchased a new Jeep Compass 2018 in March. It started making the chirping noise in May especially when I was going around 60mph and had the AC fan on. After having looked all over the place, I found out it came from the area under the dashboard on the passenger side. I took the car back to the dealership and got the motor blower replaced. Strangely, the noise has come back for several weeks. It happens randomly and usually comes up in the morning after I got the car running. I have brought the car back twice but nothing got fixed because they could not find the noise. On the second time, I drove the car over right away and had a consultant listen to the noise and had a ride with me. Again it was not fixed because the technicians could not find or replicate the noise even the consultant had confirmed the noise was there. This is frustrating.
