I pressure washed my engine about 2 weeks ago, now my alarm is acting stupid.... The siren doesn't work at all, and the alarm will go off for no reason and flash the lights. then it stops and is fine for a day or two. Then i come walking out of a store and the lights are flashing again... I have checked all the fuses, all good. Can someone tell me where the siren is so I can check the conection there?
