I have the option and when I went to the Central Florida, Buick Grand National and T-Type club meet in old Town Florida last year there were 52 Grand Nationals there and mine was the only one with Electronic Touch Screen system. I have been looking for a new/used Temperature Door actuator motor for over a decade without success. GM part number 3052142, Delco number 1571531 was discontinued on 7/93. So rare - yup I think so.
