1997 Olds Aurora A/C Issues

I'll put my bets on a faulty gage...but that's just me.

First check to see that the cooling system is properly filled.
Next, watch you engine temperature and see that it hits operating temperature. If the thermostat sticks open the engine will never get up to normal temp. On my Aurora, that is exactly midway on the temp gauge.

your oil pressure should be a lot more than 7 lbs, your oil filter may need changing, or your oil pump could be the problem ....hope this helps....cheers

If the outside temp.sensor is reading -38 degrees then this is what is causing the compressor not to come on.You need to check the wiring to the outside temp.sensor and the sensor.Make sure it is connected.It is located on the front grill area.Between the grill and the bumper cover.Hope this helps.Good luck.

It's not too hard, depending on how mechanically inclined you are.

Had the same problem, replaced the ambient air temp sensor in front of the radiator. Cost is like 10-15 bucks. Don't worry if temp doesn't change right away. Took me about 5 miles and then it worked great.

You can buy a replacement ambient air temp sensor at an auto parts store for about $10. Its as simple to change as a light bulb and can be found behind your front bumper at the base of the radiator.

More than likely it's the A/C compressor clutch is going bad. Cut the old serpentine belt off and install a shorter belt to bypass the A/C compressor for now.

the sensor is in behind the nosecone. but this should not effect the ac system . it would it the inside temp sender said that in the auto mode only. put it in defrost mode and the compressor should be on if not you have another problem (maybe low on freon)

Both switches are simple on/off, so you can test with an ohmmeter or just bypass with a paper clip. See your diagram at the link below.
