Blower motor
Hey guys, long time no see. Finally got the corvette out, after a long winters nap. Only to find out, I have lost control of the blower motor. It is an 89, with automatic climate control. Doesnt matter if the control is on or off. Sounds like the fan is blowing on high speed. Any one have any ideas? Is there a blower motor relay? If so, where is it located?

Is a well documented common problem on C68 cars
Do a search for "blower motor runs " and see how many responses you get
I wish some people people would READ before posting and taking wild guesses if they have no understanding
of how a system functions.
There are NO relays on climate control A/c
The BCM is a solid state electronic device that controls fan speed and A/c clutch engagement.
Power supply is direct from batt through BCM to the blower motor.
When the BCM goes bad ,it can and will supply power so blower will run ( sometimes randomly ) with key out of Ign
Once again ; did you READ what I posted for you ????
Hell I even went to the trouble of telling where to buy a new BCM cheapest
