Hi everyone, I got in my Malibu after work the other day and my windows didn't work, the a/c blower didn't work and the check engine light was on. I went to Auto Zone to check the codes and it read that my oxygen sensor needed to be replaced. Would this cause the other problems or are they totally separate?

Replying to: cnotes (Jul 05, 2006 3:20 pm) It would seem possible that a portion of your ignition "RUN" circuit might be inoperative. This is one of the power feeds out of your ignition switch. It goes to 2 distribution points. One of them in right hand IP center feeds both the power windows circuit breaker and HVAC blower switch fuse. Since the vehicle still starts the problem doesn't go further back that then ignition switch itself. A few other things to check to see if any other stuff not working associated with this same circuit (your vehicle might not have these options): Sunroof, Cruise Control On/Off Switch Indicator(you don't have to test function just turn on ignition and push On/Off switch to see if indicator lights up). Finally to check out the other portion of same circuit which goes to some underhood electrical center features.... Does your Daytime Running Lamps and Rear Window Defogger work?

Replying to: cnotes (Jul 06, 2006 5:46 am) After looking over stuff in this case I have to recant my first comment and say that it is likely that your Check Engine Light and Oxygen sensor code are also being caused by same issue although I would have expected a bunch more fault codes. Did anyone provide you the exact code?? This power circuit underhood also feeds both oxygen sensor heater elements, and the fuel cannister vent and purge solenoids. If you have a 4 cylinder only one of the oxygen sensors is a heated type. The only thing unexplained by this problem would be cooling fans being inoperative.
