Hi, all.
I live in southern PA, and for a couple of years it’s been that when the evening is cold, I start the car (usually the next morning) and I have no dash electrics. That extends to the rear defrost, windshield wipers, radio. I discovered it warms up by putting on the windshield defrost and blasting it–somehow, something warms up, a connection is made, and everything comes back on, no problems. Until it gets cold again and the car’s been off for a while. Sometimes it only takes a couple of minutes, but when it’s been truly frigid overnight, it’ll take up to 20 minutes on high heat. And if that wasn’t enough, sometimes they’ll turn on quicker if we hit a pothole while the car’s still warming up.
Really, this has me stymied, and I can’t find anything online to guide me. And I don’t want to give the dealership carte blanche also.
