3336heater blower, rear defroster, sunroof stopped working
- Feb 27, 2005all,
Heater blower, rear defroster, sunroof still not
working in the 1984 BMW 528e.
Today I did a little bit more investigation. I learned
that these systems (which all run through the same
circuit) go into or through the load reduction or
"relief" relay. I swapped this relay for another but
I'm pretty sure that I've burnt out the circuit or
wiring between the battery and the fuse/relay box. And
now it seems the relief relay is between these points.
Now I'm trying to figure out where to test for
Sadly, the Bentley manual has no circuit diagrams for
the relief relay! Anyone knowing the wiring?
