It has the 3.2 engine. so where is it located, the fan is running weird. Yesterday took the car out and when I turned on the A/C the fans came on. Parked it and shut it off and started the engine they where off, did this right away.
I know that they come on with the A/C but the thing is when I pulled into the garage and shut the A/C off the fans kept running , shut the car off and 3 seconds later started it and they did not come on, The temp was high here so they should have come on without the A/C working.

Not necessarily. I've shut off the AC on my Ram, the fan continued running, but when I restarted the truck a few minutes later the AC fan remained off. Like Bob posted the curve is pretty steep.
OK, so possible that the coolant temp sensor showed the engine hot enough to run the fans immediately after the A/C was shut off, but cooled down just below the turn-on threshold before the restart. Those thermistors have a very steep resistance-to-temperature curve. I have seen them change over 1K ohm per second.
Drove the car today and the A/C worked then it didn't. checked the compressor and pushing the button you could hear the compressor kicking on but not cold. Looking to recharge it and see one fitting on the compressor but couldn't find the other one where is it at ?
Both high and low charge ports are on the compressor manifold. They were delivered with "H" and "L" caps, one or both of which may be missing or have been replaced.
As for the fans, the ECU has both an ON temperature as well as an OFF temperature. If you turned A/C on, the threshold for temp may have been below ON but above OFF, meaning the fans would have stayed on until either a power cycle or until they hit the OFF threshold for temp.
If your system has a freon leak, it may be the evaporator. Both LH cars I've owned had the evaps fail. It's common, their lifespan is only about 10-15 years. I verified it by using UV dye, and putting newspaper down to catch the condensed water coming out of the system.
As you can see, there is a fan on temp and fan off temp AND fan off TIME for multiple situations including intake air temps, trans temps, and A/C pressures!
