ENGINE HOT A/C (Air Conditioning)
This message displays when the engine coolant
becomes hotter than the normal operating temperature.
See Engine Coolant Temperature Gage on page 3-48.
To avoid added strain on a hot engine, the air
conditioning compressor automatically turns off.
When the coolant temperature returns to normal,
the air conditioning compressor turns back on.
You can continue to drive your vehicle.
If this message continues to appear, have the system
repaired by your dealer/retailer as soon as possible
to avoid damage to the engine.

Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
It also provides an indicator of how hard your vehicle is
working. During a majority of the operation, the gage will
read 210°F (100°C) or less. If you are pulling a load or
going up hills, it is normal for the temperature to fluctuate
and go over the 235°F (113°C) mark. However, if the
gage reaches the 260°F (125°C) mark, it indicates that
the cooling system is working beyond its capacity.
See Engine Overheating on page 5-32.
No sorry its the 4.3 but here is the vin
I can clear the code through the button to reset the trip meter but no its not overheating at all the thermostat is opening and everything seems fine. As soon as I turn the key on after shuttin it off it displays "hot engine AC turned off". It was low on coolant but I filled it up and like i said replaced the sending unit for the temp gauge. As I turn the switch on you can see the temp gauge move a little but at operating temp its still stuck on low temp and doesnt move. It thinks its overheating so the cooling fans kick on but not sure what else it could be?
I tryed that and still on. I decided to dis connect the possitive cable and try and re-set the code. Once I did that, the gauge started working properly and works perfect now. I think the sending unit was bad but the computer still was holding the hot code until I reset it. Like I said working like a champ now.
Thanks for your time and help!
