Sorry - which ones? A/C heating or engine cooling fans?
Check fuses to make sure they're still ok. Remove the ones for the fans - and replace to clear any corrosion off them.
If it's the cooling fans at the front, these are controlled by a temperature switch which may be faulty.
Locate it , and measure the conductivity between contacts when cold - and when engine is very hot. The switch should close at around 90 degrees - 3/4 of the temperature gauge.
If the switch is ok, the relays controlling the fans are probably corroded.
Sometimes mounted on the fan housing - follow the fan motor wiring directly to them.
Hope this helps.

P0321 Spark Reference Circuit. The spark reference signal is used by the PCM to improve ignition timing accuracy during crank and at engine speeds of up to 1,200 RPM. The spark reference circuit allows the use of ignition control mode below 400 RPM, eliminating the need to utilize module mode during start-up, and also allows the PCM to calculate true crankshaft position in 1/6 the time that use of the fuel control reference signal would permit.
During normal operation, the PCM uses the spark reference signal to control ignition timing until the engine speed exceeds 1200 RPM, at which time the fuel control reference signal is used. There is no connection to the TCS.
If everything checks ok then the PCM is defective PCM.

you can go to advance auto and use there scanner for free to clear the code its called an obd2 connection or when you disconnect your battery you can touch your black negative cable to your red positive cable that connects to the battery and it will completley drain everything and reset but warning you if your trying to get the car through emissions your gonna have to drive the car 50 or 100 miles after you disconnect the battery each time..

also check to see if tube that runs your climate door is not pinched or broken. the vaccum tube that runs the climate door is behind and under the battery. i had same problem a year ago and the tube was partially cut. i fixed it by cuttinga piece of aquarium tubing and spliced it back together. one other thing.....check to see if your radiator over flow cap is tight. your cap maybe bad and or cracked this would also cause the problem.
