Nissan quest 2000 electrical problem?

my power windows and locks only work whenever i hear a clicking sound coming from behind the brake release panel. my friend who installs aftermarket alarms for 10yrs+ tried to troubleshoot the problem and was lead to disconnecting the control assy smart entrance (part28596 7b001) loacted behind the speedometer just to get he part, but after reconnecting it i started getting additional problems. eg; 1) beeping sound occurs while door is open without key in the ignition. 2) when activating alarm signal lights used to blink indicating activated and horn used to honk not any longer. a/c button is on even when its in off posiition except when control button is in other position other the a/c.(if you dont understand just ask me what i mean???) this is original alarm.the auto starter is working. i was avdised to change the battery because it could be a low voltage. battery is 3 years old discoonnected battery terminals while car running and a/c on blast. works fine. i do have white powered constantly accumilating on the positive batery terminal. how do you get rid of that?

the milage is 127k, timing belt changed at 120k, tie rods changed, just needs new shocks. you could email me at naci9726@juno.com or call me 9178260705..

hi you really do have a lot of symptoms i think you have an earth lead problem sometimes these earth connection,s are in awkward places behind the dash and other hard to acces areas get your friend to go over these earth points. pour boiled water over the mouldy battery terminals and coat with petroleum jelly
