Electric problem on 2002 Jeep cherokee 6
I had a similar problem, Mine turned out to be a weak cell in the battery. Here is what I did to find it. First, check what postion is the dome light switch in when this problem happens?
Disconect the negitive battery terminal. connect a volt, ohm, amp, meter in series between the negative battery terminal, and the disconected negative battery cable. How much voltage is showing on the meter? open the door does the voltage go up, or does it drop off?
Close the door wait 30, 40 second voltage should start to decrease back down to 0. This is normal the dome light uses a module to control the dome light delay.
If the voltage does not drop down to zero with the door closed after a min. or 2, select the amp setting in your meter, read the amperage draw. This is what drains the battery, the higher the amperage reading the quicker the battery will drain.
With the meter still hooked up remove one fuse at a time, when the amperage drops off you have found the defective circuit.
