I have a 92 grand caravan SE 3.3. my door ajar alarm keeps going off while I am driving. I have disconnected the driver and passenger side door sensors and it still dings leading me to believe its the sliding door or something else. any input on fixing the problem is appreciated before the dinger drives me insane.

 

Its the sliding door ajar switch. This was a common problem back in the early 1990's. Get a new switch and install it. To make the ajustment, just close the door.
