I have a 01 Pontiac Aztec,never had any trouble with it till a couple months ago.It started off my alarm going crazy,and at first I could lock it with the clicker,and then before I got back to it to leave,the alarm would go off,then it even started doing it when I only locked it with the button inside.Then later while driving down the road it started going crazy,lights flickering,gages going crazy,like when the alarm goes off,but even the radio was going on and off,but the horn wasn't honking.If this wasn't enough recently it has started doing more stupid crap.The hatch pops open everytime you put it in park,or cut the key on or off.Then doesn't want to latch back.It is getting on my last nerve.And everytime I take it to a mechanic,ofcourse it won't do it.So no one can tell me,and it doesn't show up on the machine they hook it to.Plaese help.Thank you to all answers in advance.
