After 2 months of observation and a trip to the service center without a definitive explanation, I’ve figured out 1 definite contributor to the infamous squeaking/chirping, which is presumably coming from the condenser/radiator fan. Cold weather is a definite component to this problem . I live in a cold climate(Wisconsin) and as the temperature drops, the chirping becomes louder and more consistent. I’m not certain If moisture had gotten into the fans motor or not, but after blowing hot air into the front of the car via torpedo heater, the noise went away. I have not yet determined if this is a result of the components being warm or moisture drying up. But blowing warm/hot area into the front of the car eliminates the noise. At least for the short term. When the car is re-exposed to the cold temperatures, the chirping returns. I’m uncertain if this is “normal” or not. Hope this helps all of you model 3 and Y owners with this problem
