GMC ACADIA COOLANT PROBLEM

2007 GMC Acadia

My cooling fans are not working in high speed but working in low speed, when I remove the engine temperature sensor they got work in high speed it means that relays, fuses and fans are good, then what do you suggest to do here?
the radiator get so much hot and the A/C also comes to hot.
when I m driving then every thing is good may due to the fresh air.
please tell me what is wrong with this?

Fackir: Do you solve your problem yet? I having exactly the same problem with my GMC acadia. Everything looks to be ok, New water pump, New thermostat, spacial GMC coolant, but some themes my car get hot, and I do the same test disconnecting the engine coolant temperature sensor, but some times start both fans in high, but sometimes only the second one.

If you find the solution, please let me know.

Thanks.
