Thank for thaking time to help me!

Answer
P041 CURRENT = No camshaft reference signal from the ignition module.

The problem can be either the camshaft sensor and or the ignition module.

P039 = Fault in the overdrive circuit of the transmission.

As to the blower problem the fault is either the blower motor and or the A/C-Heater PROGRAMMER.
