Hello,

I owe a nissan maxima 2011, I replaced the compressor since then after a couple of days the ac controls stopped working and after reseting the car they started to work this happened a couple of times but after a week it completely stopped even resting the car wasn't working. Later on i came to know the ac control amp was the issue i got it fixed. after two weeks now while driving the car the AC suddenly stopped and the controls were hanged they weren't functioning at all. I switched off the car and turn it on again this time the controls had no power. I know resting the car again will help but the problem is why is this happening ??? this started to happen after i installed a new compressor.

Just a guess at this point but seems you may have an intermittent connection to the Clutch on the AC (you mention that this is the ONLY delta...no new sensors, or drier or expansion valve) that may be shorting out. This COULD take out the control amp but I would think it would blow a fuse first....unless it was a really loose connection just kind of arcing. What led you to replace the compressor? (In search of more clues.)
