2012 C250 Melted ECU Relay
A little background first. This car is beat to heck. First it needed a starter and new battery and then I changed out the alternator for her. But just before, she had damaged the front end in the drivers side and the Windshield washer sprayer came on and would not stop!
So I changed out the alternator, cleared all the codes. alet it run for a good hour with no problems. She comes and gets it, drives it to a store and then the ECU relay melted! What in the world! You could also hear some motor running right below the driver side headlight (assuming something to do with the windshield washer?
Any Ideas at all what would cause this to overload and melt?
