and as with AC they working fine this give me an extra point to tell me the fans and controler are ok and the AC relay as well
yes as you say i tested the voltage and i got aroung 6 volt power so were exactly my issue ? where i can find this resistance and how i can replace

" yes engine is over heating and you can safley remove the raditor cap as coolant water will not burn you and as Tech. Man he told me this can tell us you dont have any issue in the engine "

You do not have an overheating issue. The temperature gauge is not showing an accurate reading.

When engine is started from cold, it takes at 20 minutes or more before the cooling fans are commanded to come on.

There are scan type thermometers available. Get one to check the coolant and engine temperature to see what they are.

But in the scan tools we saw the Tem. Reached 105

That is a great idea as I suggested earlier a infared temp to measure actual engine temp.

Is that celluis or fernhit?

Its celluis , we did this testing as wee said maybe the Temp. Dashboard give us a wrong sign but when we saw this reading we ensure the dashboard sign is working fine

Thats 221 F thats not super hot what was the gauge reading when that temp showed on the scan tool?

Yes I now but we stopped at this reading as we were testing if we getting a correct Temp. Or not

At 105 Celcius, the temperature gauge should be showing normal operating temperature. As the system is under pressure and coupled with coolant used, it can reach 125 degrees without boiling. Is coolant being pushed to the reservoir at 105 degrees?

It sounds like the coolant might not be circulating since you said you took the radiator cap off when it was 221 F and the coolant did come out. Which you never do when the engine is hot.

I replied but cant see where is my post
anyway we were testing the Temp. Dashboard if correct or not and the fans should work at 95 so when it reached 105 we ensure the Dashboard is correct so we stopped the testing and if we didnt stopped it will goup more
