2001 Grand Cherokee Completely Dead
On two occasions yesterday I heard a buzzing noise after turning off the engine which lasted for a few seconds. After the second time of hearing this noise I went to get back in the car and the doors would not unlock using the key fob. Had to open manually. Tried starting the car and nothing. No sound, lights or anything. Continued trying to start the car while waiting for hubby to come to the rescue and it finally started and seemed fine. Drove home and did not hear the buzzing noise when turning off the engine.
Husband thinks it may be a bad relay or something causing an open circuit.
Where should we start with trying to find the problem?
Also, one day last week went to start the car and the sunroof suddenly started opening.
Any suggestions will be greatly appreciated.
