Re: climate control replacement

[Sachelle Babbar <sbabbar@iris.nyit.edu>]

Up to 85 1/2, can't attest for the crossover date, had the older style
Delco unit with the defrost button. The relay on turbos was in the relay
block underneath the steering wheel. I have three of these units. Hated
them because there was no manual regulation of fan speed in anything but
auto. Even then, there was no real control beyond temp changes influencing
the fan speed. I shouldn't complain. At least mine worked.
