You need to note which year you have and if you have manual (C60) or electronic (C68). If manual, the Blower Relay and if electronic, the Blower Control Module can cause the Blower to run at all times.Just got this vette not too long ago. Im a newbie so im just starting to learn about vettes. The a/c blower motor stays on constantly even with the car of so I unplugged it. Any info on what it might be? Thanks in advance.
