Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello my name is ***** ***** thank you for your question.
Is the car running hot? If engine temp gets to high, the computer will kick off the compressor since it's a load on the engine.
Let me know
You did't touch any AC lines right?
sorry, wife was talking to me.
Trying to think what would cause this. If you bleed the coolant system the way I outlined it, you really should not have any issues. Was it doing this before the Alternator? Where did you buy the Alternator?
Do you have a Volt Meter?
What is the voltage with the vehicle running and head lights on and rear defroster ON?
It is very common for after market Alternators not to work properly. It could be intermittently not charging properly.
That is low... It shouldn't be lower than 13.9 volts..
Normally with no loads, it should be 14.3 volts. With loads I would expect to see 13.9 to 14.1 volts.
May want to recheck those voltages.. Once with loads, and once with out. Loads meaning, AC on, Lights and Rear Defroster.
Well you have two systems you need to look at. The charging system and cooling system. If charging system voltage spikes low, the computer will also turn the compressor off
Once you start the car and have it running, check voltages with loads off. Then turn the AC on, Head lights and rear defroster and double check voltage. Once you give me voltages, I will try to think if there is something else we need to check. It's sounding like it's going to be one of the two systems in my mind..
