I hava 2002 mercedes e430 Now the alarm does not signal on

Customer Question

Hello, I hava 2002 mercedes e430 Now the alarm does not signal on the locking with the remote only the opening does one blink of the outer lights. the trunk lid with the remote did take as many as 20 or more pushes to open the trunk unless I just turned the car off then it worked right away. Now the electris of the rear latch do not seem to work at all i have to open the trunk with the emergency key manually. Also the turn signals on both sides blink very irregular. I do not even try to set the alarm now as it will go off at any time so i just lock the drivers door with the manual key. the door locks go up and down fine but do not make the lights blink upon locking.One day in the rain the little green light on the headlight switch was flickering.
