The radio is suppose to go off when you open the door. If I do this, then it comes back on after by itself. Also the clock might stay on and run down the battery. 3 times the skylight opened by itself. The interior lights sometimes work and sometimes not. One time they stayed on and I couldn't turn them off and it killed the battery. The mechanic said there is a part starting with the word 'remote something' that isn't manufactured anymore that it might need.
