I purchased a New to me used 2014 Escalade ESV Platinum. The power running boards were “stuck” extended. I was able to free up the passenger side with simple deep cleaning and lots of lube. But the driver side is FUBAR. The motor is smoked. Completely corroded and done done. There is no ID tag left on the motor. Who was the OEM manufacturer for GM? Or who knows of a good aftermarket motor. I would be happy to get either the motor by itself or as the assembly with hinge. My concern is how wildly varying the prices are for aftermarket I’ve seen from $76.00-$1500.00. Looked between GM parts sites, RockAuto, Amazon and EBay. Any one have experience with any of these aftermarket?
