My max acting up lately whenever temperature drops. The power door locks work as it supposed to be, but whenever the temperature drops it opens and closes itself while I’m driving.
What do I need to change? I’ve changed the master door & window control switch module on driver’s door but no use. My dome light is not working either… checked the bulb & fuse but no problem found.
Any thoughts?

Do you have an aftermarket alarm? I have my Compustar to lock doors after reaching 15 miles per hour and at fisrt it was doing just that. The installer readjusted and now it working without any problems.

its the little knub in your door jam the switch rubber stopper is all F'ed up. thats whats wrong with mine, but im just too lazy to replace it.

I removed my alarm completely for that reason...
also, my side rubber switch looks fine.
Maybe it's becasue I've bad body control module?
