The rack and pinion on my 90 Bonneville **** out so I've been having to drive my 66 Polara. The temps here have been the negatives but with it plugged in the car starts right up. With the below zero temps my blower motor has been making a squealing noise until the car gets up to temp and has taken about 5 minutes to kick on after starting the car. Is it normal on these? Just hoping it's cause of the cold since replacing the blower looks like a headache according to the FSM. When the temp is about 5F or above it kicks on right away with no noise.
