Question about 1989 Chevrolet Corvette
Sounds like a bad relay. For 89 that should be under the hood i think. Go to advance/auto zone as it should just use a regular relay. Look in the haynes repair manual while there for where it is located.
If not a relay then could be a bad switch (the dash unit)/

The switch , relay, or motor are shorted out .
First locate relay and remove it to turn the blower off.
If you want to do the diagnosis yourself ...remove the switch first and see if the motor stops. if it does you've found the culprit. If not move onto relay if the relay removal kills the motor thats good news. if it doesn't then this thing gets B+ right from the battery at HIGH SPEED. Your gonna need Shop Manual
to show you where this thing connects to the battery.
So either the switch, relay, motor , or resistors ( in your case where battery connects to the motor are your problems.
Unlessyour really good with electrical items pull the relay and bring it to a repair shop.
