First time poster here! 2015 suburban. Ac quit working. Clutch cycles on/off as usual. Fans won't go above 12%. I'm also no longer able to command the fans with scan tool. If I unplug the temp sensor, the fans kick on high. On the ac, low side pressure is high, high side is low. Do I have more than one issue here? Any help is appreciated!

 

It may be an issue with the blend doors not opening all the way. If that is the case consider replacing the plastic parts with American made aluminum parts. Visit our site @ Blend Door USA for more information.
