This is a nice low mileage HVAC control for your Cadillac. I'll give a 30 day warranty on this part as I could test that it operated the electronics as best I could with no motor. If you are not happy with it I'll take it back. Fits 77-80 Deville and Fleetwood as well as 79 Eldorado. 

All packing/shipping/moving of parts is done on weekends. Ebay is not my full time job and my storage is an hour round trip from my house, so moving parts around on weekdays is not in the cards. If you need something immediately, I'm not your guy. The handling time is built into my delivery estimate on auto parts. All large items are packaged by a shipping company, and go out on Monday or Tuesday depending on how busy they are. I package all smaller items and drop off for Monday pick up.
