SOURCE: outside temp stuck on -40

when its at -40 usually its because the ambient temp sensor is not sending the proper signal to the controller.. it may just be disconnected.. the sensor it behind the grille.. it has a 2 wire connector to it ... itf its connected it may havea broken wire from body damage in an accident... its rare that the sensor fails..

If the outside temp.sensor is reading -38 degrees then this is what is causing the compressor not to come on.You need to check the wiring to the outside temp.sensor and the sensor.Make sure it is connected.It is located on the front grill area.Between the grill and the bumper cover.Hope this helps.Good luck.

Ambient temp sensor on chevy impala is reading -40


If you replaced the right sensor, there must be a problem in the wiring to the computer.
You did reset the computer - hit ac and recirculate buttons at the same time ??

WHen we use the auto car starter, it blows cold air, and a lot of it. Its nearing the winter here in New England and I need to know how to set up the starter to blow warm air. Any ideas?


Start the vehcle and let it warm up then set all the controls to heater? Then turn off the car. Use the remote start to start the vehicle and check the controls are still set to heat mode.

Air conditioner wont work if outside temp is over 70 97 chev pick-up it works great in temps remain cool outside any help would be helpfull.


Sounds like you are low on freon and as it gets hotter outside your AC system can't keep up. Check into getting the system charged and that should take care of it for you. Thanks for rating my response and for using FixYa!

the sensor is in behind the nosecone. but this should not effect the ac system . it would it the inside temp sender said that in the auto mode only. put it in defrost mode and the compressor should be on if not you have another problem (maybe low on freon)
