Wasting my employer's Broadband connection while the Stock Market is shut I can confirm the following

Refrigerated air system was first fitted in a Packard

Electric windows in a Daimler

Power steering was investigated by F W Davis when he worked for the Pierce Arrow Car Co; he left and formed his own company to continue development and it was commercially available by 1951.

Early central lock was a pneumatic cystem fitted to some Mercs but I cannot say if it was the first system.
