My windshield wipers are stuck on, full blast. My turn signals stopped working. My info settings won't change/update. Car drives fine otherwise. No CEL. I had an ECU spacer installed about three weeks ago, followed promptly by a long vacation in the mountains where I did some pretty spirited driving mixed with extremely rough terrain (for this car). I wasn't able to fit the cover back over the ECU, and there is definitely some dirt buildup on it. Could that be causing it?
