You may have a radiator fan relay problem. Check the fan/blower motor itself by hooking it directly up to the battery. Try locating the fan relay and check it out. If you purchase a Chilton service manual, it should specify how and assist you with more info on your problem. If you don't want to buy one, visit you public library and see if they can help.
Also, check the water pump belt and water pump. If the water pump on my '97 Aurora siezed up and caused the drive belt to disintigrate. The olds will stay cool for a while, but in hot weather it will overheat. One cannot see the belt from the topside of the engine, there is a shield over the assembly. Good luck!
I HAVE A 96 AURORA WITH THE SAME PROBLEM. CHECKED EVERYTHING AND IT CAME DOWN TO THE PCM. THE EASIEST FIX WILL BE TO GO TO THE RADIATOR OVERFLOW TANK AND UNPLUG THE COOLANT LEVEL SENSOR. NOW THIS WILL CAUSE THE MESSAGE DISPLAY ON THE DASH TO GIVE THE ERROR MESSAGE "LOW ENGINE COOLANT" BUT THE FANS WILL KICK ON AT AROUND 175 DEGREES. ONE FAN PUSHES AND ONE PULLS AIR. NO OTHER PROBLEMS WILL SURFACE BY UNPLUGGING THIS. I DID THIS AT 188K I AM NOW AT 281K AND SHE STILL RUNS LIKE A TOP. JUST BE MINDFUL OF YOUR COOLANT LEVEL SINCE YOUR SENSOR WILL NO LONGER ALERT YOU TO A LOW LEVEL CONDITION.
The 1995 Oldsmobile Aurora blower motor relay switch is located beneath the dashboard on the passenger side. The blower motor relay switch should be labeled as such.
under dash on passenger side
A thermostat.
Same problem on mine...I had the blower motor module replaced and it works great.
The blower motor resistor is generally located close to the blower motor.
Remove cover on firewall under the hood, then remove the cabin filter and you will see the blower.
Behind glove-box, behind engine control module
switch contact"s
the thermostat needs to be replaced
