Need advice...electrical is haywire

Need advice. My 2001 dodge durango is doing really strange things...dome lights and headlights come on and off for no reason, horn beeps, wipers go on and off, 4wd light goes on and off, warning "beep" goes on at random, etc. Any ideas?

do you have any after market items installed like remote start?

Sure sounds like either the above or bad BCM or ground to the BCM

No remote start here...so we'll look at the bcm and the ground...thanks for your input!
