2002 Olds Aurora heated seat inoperable

your vehicle has dual controlls for the heat and air. Make sure the driver side heat is on. if that fails, see if you have heat coming out of any vents on the drivers side. if not, the controller could have a bad connection of a loose vacum hosecausing the proper doors to not open or close properly.

if they were installed correctly the fuse should be in the fuse box (usually driver side under dash) marked seat heater or in an acc slot. also try looking under the seats to see if they are plugged in correctly.

I have the same problem except the back of mine works but the bottom doesn't. Passenger side is fine. Let me know what you find out if you could.

Possibly.... the only way I know to diagnosis this issue is with an amp meter in the circuit that heats the seats. Compare LH & RH seat heating current draw. If you find the pass seat is NOT drawing the same amount of current, further troublshooting is required. There are TWO heating elements installed in the seats -- seat bottom & seat back, and they are connected in 'SERIES'... so if either element goes/is 'OPEN', then it's component replacement time. There is a thermostat in the heating elements -- it regulates the seat temperature. One must isolate the two elements & check each one individually (seat bottom - checking resistance... and seat back - checking resistance). whichever one (or possibly both) are 'OPEN'. If you find resistance is normal (3 to 5 ohms), then the problem/cause may be in the switch (or its contacts). Using a test light (12 volt bulb), check for power (battery voltage) at the heating element connector to ground (chassis). If the bulb lights up, you know you have power at the switch and is sending it to the heating elements.

Look for a hole or opening in the fire wall from under the hood.
Wire harnesses, AC lines and heater hoses usually have a grommet that closes off the air leak where they come into the passenger compartment. One may have rotted or simply pulled out. If pulled out, work it back in.
If you can get under the dash with the seat pushed all the way back, you can put a drop light under the hood, get under the dash and look for the light coming in. If you see anything.....PLUG IT!! :-)

You may need to change your a/c switch..and that's if you have a dual climate control switch...GoodLuck

Look at the switch itself first - it almost sounds like the switch is turning off right away.

Replace fuse under the back seat. Look in your manual, look in the fuse section and it will tell you which fuse it is exactly

The most likely failure point is the driver heated seat elements. They probably have excessive resistance and once they warm up a little they short out the module and it defaults to not working. I would recommend replacing both upper and lower driver seat elements.
