2001 sable..while idling i smelled rubber burning, then a loud hummm from the upper right hand side of the engine (as you sit behind the wheel) and then smoke only from that area..noticed some "buckng" while idling at traffice light for a few days before...this problem stopped for 1/2 day and then began again yesterday...

Thank you so much for your prompt reply. My son stopped over late this afternoon and I also told him about the problem. He started the engine and told me to press the front defroster button, the the inside heat plus defroster button combined; the problem started again. Apparently it has something to do with the air compressor. Both of the heater buttons (upper and lower heat but not the combined button) are ok. It's just the ones that I mentioned. He's going to come over and unplug the compressor. Thank you, again, for the prompt reply. Trying to diagnose without the "patient" there is like asking a doctor over the phone why the baby is running a fever. You've been great. Thank you so much for your prompt reply.
