Review: It’s cold in here - Works great. Exactly like the OE part
Review: Works great - UPDATE 01/23/20 I've been using one if these as a mode actuator and another as a blend actuator for a few months now with zero issues. No calibration loss in an auto climate control application, great OEM made in Korea product. ~~~~~~~~~~~~~~~~~~~ UPDATE: 11/08/19: USED AS A BLEND DOOR ACTUATOR This has been running well as mode actuator on an '03 Suburban for a few weeks. I've heard of other instances of this same part being used as a temperature (blend door) actuator and I decided to take a shot and use it for my passenger side blend door actuator with auto climate control. The track that comes with this model pops off the actuator and you are left with just the unit. I was a bit apprehensive about using it in the blend door position, but I just finished the job and it calibrated just fine as a blend door actuator using the same step list below. I used this in place of the original GM p/n# 52402588 that was removed. The job itself took me about 4 hours since I had to remove the passenger airbag and the onstar module takes up a lot of the work space so it was a very tight area, and I did disconnect the negative battery cable for this. I used a pass through ratchet with a 5.5 MM socket to get the mounting screws off, there were only two screws, but a nightmare to get to. I will update in a few weeks to make sure I have no issues using this mode actuator in a different capacity. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ORIGINAL: First off, yes, my product was made in Korea, but this does not keep it from being a genuine product. Do some research people. NOTE: REMEMBER TO FULLY INSTALL THE ACTUATOR, DON'T SLAVE IT IN BY JUST PLUGGING IN THE CONNECTOR AND TURNING IT ON, YOU WILL OVER EXTEND THE INTERNAL ACTUATOR GEARS AND MESS IT UP!! I used this as an actual mode actuator for an '03 Suburban with auto temperature control. The mode gear is hard pressed together but it will come apart , just don't pry it side to side, straight up will do just fine. I didn't use the new gear, just the actuator, but after performing the hvac recalibration everything worked great. My mode was stuck in feet only, now it works in all settings. Note: the mounting bolts were 5.5 MM. DISCLAIMER: FOLLOW RECALIBRATION STEPS AT YOUR OWN RISK For manual systems it does not matter where the a/c controls are set but if you feel the need to do something, turn the blower switch on (I prefer speed 3) and set the temperature sliders about .5″ to .75″ from full cold. For auto systems, press the auto button, with the key on. Turn the ignition off. Remove the HVAC/ECAS , 10 amp fuse in the underhood fuse box* or disconnect the battery for one minute. *Fuse locations can vary from year to year and between different models. Install the HVAC fuse or reconnect the battery. Start the engine. On systems with auto a/c controls the controls will default to 74 degrees F when the ignition is turned back on. DO NOT TOUCH the a/c controls. Let the engine run for 1-2 minutes. Turn the ignition off for at least 10 seconds but no more than 30 seconds. Restart the engine and then test the a/c controls.

## 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.

### ⭐⭐⭐⭐ I guess it's genuine AC Delco. "Made in Korea."
*by C***3 on February 25, 2021*

Installed on a 2003 Suburban. The actuator seems to be good quality but it's not exactly identical to the original unit. The original actuator was assembled using screws, the replacement actuator just snaps together. Cheaper manufacturing. We disassembled the bad actuator and the large drive gear is plastic and was cracked causing the gear to slip. Removal and installation of this part is NOT easy due to learning curve. Second time would be easier. When installing, take the plastic cam assembly off the actuator and position the cam assembly on the heater box first. Then carefully rotate the cam assembly as needed to line up with the clocking of the actuator shaft bore and push the actuator onto the cam assembly. Install screws. We just started the truck and the actuator began working properly with no problem. This fixed the problem where the air flow was stuck on defrost.
