A-C/cruise/PS woes - 1994 non-ZR-1 A4 Vette - ZR-1 Net Registry Forums

Just an update from spending time working the issue(s)...

Programmer rebuilt and back into the car, although on start-up it seems to still show 75 degrees and 0 fan speed (???)

New a/c clutch assembly also in. Schrader valve on the high side was leaking so that was replaced also. Everything seemed to be working but the blower motor (original to the car) is now doing so intermittently. A fist-bump to it a la The Fonz method seems to shock it back into working, but I'll be getting a new blower motor in there soon. Since the blower control module is original also, I'll throw a new one in for giggles and grins anyway while I'm at this project.

The outside temp still seems wonky despite the programmer and head unit rebuilds, so I think I'll see about a new outside temp sending unit as well.

Will see where this all goes...hopefully one day it will actually work as intended again!
