2005 Fleetwood Southwind W22 overheating on temp guage

i recently saw that my temp guage reads HOT.. Does anyone know if the dual fans on the condenser needs to be on when the AC is running? I have verified that the fuses and relays are good, the fans are good as I ran them direct to the battery and they ran. When I run the AC I get cold air, but the fans don't come on.... There is water in the radiator and coolant in the coolant tank. Any help would be greatly appreciated..

I believe the fans should run any time the A/C compressor is cycling.

BUT; those fans are not for engine cooling, if your getting higher than normal engine temps , then the operation of the engine fan thermal hub needs to be checked. If you don't hear the engine fan ROAR when you notice the temperature high , then it's probably the hub that needs replacing.

On mine (2004) the two fans were controlled by the engine computer and did not run all the time the AC was on.

You can download the service manual for the instrument panel HERE There is a self check procedure that you can run to see if the heat gauge is working.
The gauge is really a glorified idiot light that only has 3 or 4 positions so if it is reading in the red the engine is really hot.

An afterthought, look into ScanGauge II, it reads the actual temps/pressures.

I took the rig to the shop. They ran it for two hours, checked everything, the temp guage stayed normal the whole time. Thanks to all for your responses..
