If the compressor ls operating then either the heat control is stuck on heat, or the diverter door is not opening. Turn on the heat an see if the heat temp will go up and down, If its ok then a door is probably stuck in heat mode. Check for vacuum leaks, as the door operates on a vacuum.


How do you fix a 1998 Mercury Sable if the AC stays on when heater is turned on?

cars that are equipped with ac are supposed to run when the heat selection is on : max a/c , a/c , mix or defrost. the ac pump dries the air that flows through it which helps to clear the windshield and also to help to feel cooler in the summer . i have pulled the plug on the compressor before to turn it off during the winter months but it is just fine to run Also, heat settings keep the compressor running to prevent it from seizing. The number 1 cause of compressor failure was due to lack of use during the long winter months.

How do you fix an air condiosoner pump because it does not spin or work?

Do you mean that the AC clutch does not engage the compressor? Or do you mean that the AC compressor won't turn even if the clutch is engaged? If the compressor is siezed and will not turn even if the clutch is engaged, the only choice is to replace the compressor. If you can turn the compressor by hand (understand that the belt pulley will turn freely with the engine if the clutch isn't engaged) but the compressor clutch isn't engaging, it might just be out of refrigerant. There is a sensor, usually somewhere near the receiver/dryer) that detects the "low side" refrigerant pressure. Once the refrigerant pressure at the sensor drops below a specified level, the compressor will not turn on. In other words, if the compressor clutch won't engage it might just be out of refrigerant.
