S70 GLT turns off after using AC

Post by S70GUY »

So yeah, This is a bit strange, but when I use the AC, my car's revs drop and it turns off. I have to turn off the AC and press the accelerator several times for it to turn on. Has anyone had a similar problem?

Check your charging system(alternator and voltage drop).
If that checks out ok...then ac compressor clutch bearing.
