I installed the power amp, getting the power from battery. Got the power through the wiper crow plug hole. Did not start the car for 3 days while taking the time installing the amp and wiring. During that time, doors/trunk opened for long time, power seat move up/down. After everything completed. The amp works fine.
Wanted to back car out of the garage. The car won't start. It makes loud click noise and the wiper swipes regardless.
Lights, fan, turn signal everything electric thing seems to work. I notice the lights dimming when test the amp.
Other than removed the wiper may touch or the wiper wire but I doubt I touch any other wire, short circuit and any wire.
Desperate need help! What should I check first? and move forward from here.
