Another blower motor problem
 

I have a 1997 deville,,,one day I got a very low refridgerant,notice on my display,,,
seems after that my blower quit completely,,,even on colder days when I should have heat,,,
I did NOT recieve and other code,,,even checked the display,for codes by using the off/warmer method,,,,
any thoughts would be appraciated before I got to the trouble,and expense on replacing a motor

test the motor direct .. these are controlled by either a blower controller or a computer and it could be that instead of the motor.

if the refrigerant is low, you may need to refill the system.
