How come it's so expensive? $200 bucks for a relay? wow. why?
Anyone know how to test it?
Anyone know if I can mod. the normal black square relay in place of this thing?

Which fan are we talking about?

the heater fan blower. Relay is big square aluminum on the left in the engine compartment.

which one?

I thought the round one was for the heater blower fan.

and I just didn't know what the box one was for.

I am trying to figure this out now, too.

I need to fix my heater blower,

and I need to get the rear glass defroster to work, too. (it doesn't now)

tthat swuare on, on my car, I think is the defroster. There is another smaller square on next to it, for the fan motors. It is listed at around $200+.

Here, have fun with this:

There are good descriptions of what it does, and what the guts look like in the pages of this thread.
