I have a 2003 GX and, last night, the alarm kept going off. I've had the truck for about 6 months now and not had this problem before.
I'm wondering if maybe a switch on one of the doors is having a problem. Why? Well, my boys have their baseball stuff in the back (fall ball here in FL) and, if it's pushing against the back door, the light inside will come on under acceleration. Seems like maybe it pushes against the door just enough to make the switch think the door is open.
Last night was the first, "cold," night here in FL we've had since I got it (got down into the mid-50s--I know it's all relative). I wonder if it's causing the door to not push the switch in enough.
I'm totally guessing on this one. I only suspect the good switch because of the problem I had with it and the light coming on before.
If it's not that, I have absolutely no idea what it could be.
Anyone got any ideas?
Sorry if my post makes little sense. Didn't get a lot of sleep last night with it going off. Woke me up at 5:30 this morning.
