I have a problem with my central locking system/ alarm. When I try to lock my doors from the driver's side it only locks the drivers door. But if I try to open it then it opens all the doors. Same problem goes with my passanger door. There is also a problem locking/unlocking doors remotly. It never works on the first time i click, usually it works on the third try. Its like the vacuum pump gets the signal because it makes a short noise and the lights also blink but thats it. Im using WAECO MT150. I alredy checked the vacuum hoses and I didnt spot any leaks. Sorry for my grammer and I hope someone can help me with my problem.
