## Description

ACDelco GM Original Equipment Ambient Air Temperature Sensors are used with automatic climate control systems. The sensors provide the HVAC system controller with outside air temperature, allowing the controller to modify the climate-control strategy. The sensors may also provide the signal for the outside temperature in the driver information display. This original equipment ambient air temperature sensor is a GM-recommended replacement for your vehicle’s original components and has been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

Review: Sends ambient air temp info for electronic rear view mirrors, not HVAC controls. - This IS the correct sensor for sending ambient air temp info to electronic rear view mirrors with compass/temperature indicators on 2001 Suburban 1500 LT (and other Chevy/GMC models with this accessory), although I couldn't find an exact match for the part number I found on the OE, and the clip configuration of this one was a little different. However, once I was satisfied that it correctly matched the OE electrical connector, I just trimmed a little material off the back of its mounting bracket so that the new sensor would seat securely/fully in the OE bracket. Very simple to do, no effect on the function, except the OE had an additional clip that prevented rotation of the sensor in the bracket. This sensor is located on the driver side, in front of the AC condenser/radiator combo, right next to the much smaller transmission cooler ... very easy to find/access once you have the front grill off. Don't confuse this sensor (like I did at first), with another, very similar one that's located over on the passenger side at the bottom left corner of the AC condenser. That one has a slightly different electrical connector that won't fit in this part, and sends ambient air temp info to your electronic HVAC controls (for vehicles so equipped). I stopped paying attention to the temp readout on my mirror years ago; I always assumed there was something wrong with the electronics in the mirror itself; figured that would be really expensive to replace, and just didn't want to bother with it. However, once I figured out the problem might be due a failed sensor located somewhere other than the mirror itself, I identified/located the sensor, ordered/installed this part, and now it's showing an accurate temp reading again. Duh ... could have easily fixed it years ago, but it's all good now.
Review: Good and cheap (Bueno y barato) - Hola a todos, yo compre este sensor por que el anterior se dañò, y presentaba variaciones de la temperatura, haciendo que se apagara el AC y encendiera la calefaccion cuando la temperatura real era de 30ªC ???. Yo instale este nuevo sensor rapido y facil, sin herramientas, solo un par de minutos. Lo he probado y se soluciono el problema de indicaciòn erronea de temperatura, ahora todo funciona bien. Este sensor es de fabricaciòn china y funciona bien. Lo recomiendo por que funciona muy bien y el precio es muy bueno. Saludos, Ali desde Venezuela. Hi all, I bought this sensor that the previous damage, and variations in temperature, causing it to shut off the AC and turn on the heating when the actual temperature was 30 º C???. I installed this new sensor quick and easy, no tools, just a couple of minutes. I tried it and it solved the problem of erroneous temperature, now everything works fine. This sensor is manufactured in China and works well. Recommend it because it works very well and the price is very good. Regards, Ali from Venezuela.

## Questions & Answers

**Q: How does my vehicle’s AC system work?**
A: The AC compressor pressurizes refrigerant gas, which moves to the condenser. The gas releases heat, condensing into a high-pressure liquid. After cooling, the liquid passes over evaporator coils to cool the air as it is blown through the vents.

**Q: What are the signs the system needs service?**
A: Common indicators of an air conditioning system in need of service include warm and/or weak airflow through the vents, frequent on/off cycling of the system and a strange or musty odor.

**Q: Is the puddle of water under my car a sign of AC problems?**
A: Not necessarily. Condensation typically builds up on the AC evaporator and the water is drained at the bottom of the vehicle. That’s normal, but a larger puddle combined with reduced AC performance could indicate a problem.

**Q: Does low refrigerant mean there’s a leak in the system?**
A: In most cases the answer is yes. AC systems in older cars will experience refrigerant leakage over time, but a later-model vehicle that needs continual refrigerant recharging typically indicates a leak.

**Q: Can a new cabin air filter improve AC performance?**
A: Yes. A very dirty or clogged cabin air filter can reduce the airflow of the AC system, reducing its cooling efficiency and making the system work harder than normal. Periodic cabin filter replacements help the AC system keep its cool.

### ⭐⭐⭐⭐⭐ Fits and works on '02 Trailblazer without issue.
*by B***S on January 12, 2026*

On the '02 Trailblazer, this temperature sensor mounts between the grille and front of radiator. Easy to install - I was able to change out this part without having to remove the grille, although it's mounted in a very tight space. Fits perfectly and operates as intended restoring ambient temperature reading back to normal. My previous temp sensor was stuck on 160-degree F temp all the time - which negatively affects the engine performance, HVAC, and cab display reading.
