In my 1999 Quest the front blower (heat, AC, ventilation) does not work at
swich positions 1 - 3, but works at 4 (full speed). In 2001 Hynes repair
manual, on page 12-59, I located the likely problem spot: the "front blower
motor resistor" block has 3 resistors and a fuse. If the fuse blows, this
would cause the problem I see.

But where the "front blower motor resistor" block is physically located in
the van, I don't know.

Will appreciate any suggestions.

Thanks,
Mike

Mike,
I have a tech note regarding the same problem in the Sentras. If
Nissan does things consistently, try looking behind the glove box,
next to the heater fan (where it is on the Sentra). According to the
tech note I have, the problem is due to failure of the resistor. They
give a Nissan P/N 27150-2M105 ($24.83). It's supposed to be a plug in
replacement.
Good Luck.
GEO

I am having the same problem with my 1999 Sentra. Before I start taking
things apart do you know where I can find the resistor or if this is even
the same problem? Are you saying that maybe I should replace the entire
motor?

Thanks,

Bob

It's in the blower housing or in the airstream close to it. That "fuse" is a
thermal limiter type fuse, easier to replace the whole block. Also the
reason these fail is ussually a blower motor that is drawing too many amps.
In a lot of cases, just replacing the resistor/fuse is a short term fix.
