2000 v6 accord heater problem

[TARHEELS1]

I had the computer replaced in my 2000 accord v6 and now the heater does not get as warm as it did before.Before it would be warm when the control read 70,now it doesn't seem to even start getting warm until it is between 80 and 90.The fan blows fine.My question is could replacing the computer cause this and if not what could?It was the pcm? control module that was replaced,if this helps.Thanks

I'm not sure what could be happened, but you can try to unplugged the computer and the battery, then plug the computer and then the batery, because sometimes the actuators that move the valves inside your air conditioning module are not open enough and ir you do that you can set the travel of every valve, make sure that you select and end in the temperature control, like selecting full cold or full hot and in the mode know selecting defrost or AC, if the module has actuators that could be the problem and with this you can set the full travel of the valves again. I'm not sure if in the 2000 honda is still the same valve that close the water to the heater, you can check also that
