Re: Relay Location For Heater Fan Blower On '87 325

["Ron Buchalski" <rbuchals@xxxxxxxxxxx>]

Phantom,

The problem isn't caused by a bad relay, it's caused by a bad resistor pack 
on the blower motor.  The replacement part costs less than $30.  It's 
located on the blower assembly, and access to it is gained by opening up the 
access panel on the firewall (in the engine compartment).

There are 4-5 screws that hold the panel in place, and you'll need to cut a 
few cable ties that hold wire harnesses to wire holders on the panel.  Once 
the panel is removed, you'll see the wires that lead to the resistor module 
(square curved base).  The resistors are on the inside, so that air from the 
blower can keep them cool.
