Well Tony you need to test the electrical circuit for the fan ! First you need to get a wiring diagram to find out what all is involved in the circuit ! Fuse's relays , control module etc.. get a volt meter an test the circuit ! Chrysler Cooling Fan Relay
Dirt and debris can get lodged in the radiator air flow paths. This can block the radiator and cause your engine to overheat and damage the engine.
The thermostat can be stuck close. If you feel the upper hose very hot and the lower hose cooler than normal, it may be a stuck thermostat.
Make sure the radiator and the overflow bottle are filled to the proper levels.
Bleed air from the coolant system:This is best done by running the engine with the radiator cap off until you see when the air bubbles stop coming up.
Check the radiator fans: The easiest way is to turn on the cars air conditioner and turn up the A/C fans. Both radiator fans should come on when the A/C starts
Make a pressure test by using a pressure testing tool (available at most auto parts stores). Use the pressure shown on your radiator cap. Most cars are 16 PSI or less, so don't exceed that pressure. Replace the radiator cap if it doesn't hold the pressure.
Fan not working. Check connection under vehicle. Very common connection is bad. Are has been pulled loose from someone hanging a droplight on it while changing oil or working under PT. Run a hot wire directly to fan to check high side and low side operation. If operating and connection is good. Check temp sensor located by radiator fill cap not overflow. Has a single wire. Relay is in fuse box under hood. The fan connection can be cleaned and will work for a while. But I have found it comes loose in a short amount of time. I just cut the connector off and install aftermarket. There is a lot of over heating problems with PT.

Overheating, Try this procedure:
- Dirt and debris can get lodged in the radiator air flow paths. This can block the radiator and cause your engine to overheat and damage the engine.
- The thermostat can be stuck close. If you feel the upper hose very hot and the lower hose cooler than normal, it may be a stuck thermostat.
- Make sure the radiator and the overflow bottle are filled to the proper levels.
- Bleed air from the coolant system:This is best done by running the engine with the radiator cap off until you see when the air bubbles stop coming up.
- Check the radiator fans: The easiest way is to turn on the cars air conditioner and turn up the A/C fans. Both radiator fans should come on when the A/C starts
