Roger gave me the right part number which is a 12 Volt Solenoid vickers GM #15149862 . Dealers wanted $350-$380 and the 3 I called had none in stock. Found replacements online from $154-$180. Found the original GM number for $67 on eBay. I found out that when you are on the road you can have the parts shipped to a UPS store and they will hold it for you for 7 days. So I am suppose to pick it up in Rapid City SD in 5 days. Also I found out my auto park fuse is the same as my jack fuse that is why my jacks would not work when the auto park failed. So I will be useing chocks until then. Hoping I have enough brake lining left to adjust the brake shoes, they smoked pretty good when the auto park came on at 60 mph.
