Question about 1985 Buick Century

1 Answer

Blower motor case

It is the blower motor COVER or CASE. It houses the blower motor and is located in the engine compartment on the firewall or below the cowl on the passenger side. It supports the blower motor relay and covers the a/c core or what`s that called. It rotted out just below the accumulator mounting bracket and fumes enter the cab and the car is now impracticable to drive. The part at the dealers has been discontinued and the web proved useless. I have removed the cover and may be able to plug the rotted metal or some thing. If you know how to get a replacement part new or used anything but that freezing and hot cab I would appreciate it. Can you advise?
