I have a 1997 oldsmobile aurora, the problem with it is that some times it shows that it is gettin hot on the gauge and sometimes it doesnt. it was smoking but we figured out that the radiator resivoir cap was leaking and we changed that. Then we noticed that the upper radiator hose had a ball in it. we still need to change that but could the thermostat be the problem or the sensor?

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)

I believe that this is caused by a blown Relay or Fuse. I also just went through this. I took my Relays into NAPA and replaced them all, refered back to the diagram and installed the new ones, I also, (unsure if it'll make a difference) turned every fuse to face upright and in the same direction after removing to clean the contact point with a soft tipped metel brush. Overall, replace the Relays and you should be fine.

Dealer only place to get the whole 3 piece radiator hose assembly for problem you describe. Not bad price.I know this from my experience. Trust me I searched everywhere. T-stat located where diagram that was sent. $60.00 for part

SOURCE: can't find the radiatore drain cap
