I believe the left headlamp door motor is the cause of the problem.
Disconnect the LH motor and test if the opening and closing of the doors still occurs for the RH. Repeat with disconnecting the RH.
The motor has some diodes inside the circuit board and if any is bad, it would cause the problem indicated.
As to the alarm going off when the ignition switch is turned on, it could be the secutiry system fault. Check the fuses with the aid of a test lamp. Visual inspection are not accurate.
