Everyone I have talked to say it more than likely is a Blower Resistor Switch, where is this located on a 97 Sentra? Is it easy to install? Any Information would greatly help this situation....
Im a 22y/o female would it be hard for me to install myself
It's an easy fix. It is under the passenger's side of the dash and is a 1in by 3 in black plastic piece that bolts into the blower box. It has a grey plug oriented vertically and is about 6 -10 inches right of the dash/console "island". Retention is by 2 8 mm screws that are at opposite ends of the box, again on the vertical. DL the B14 FSM at the top of the B14 section and it should show you everything you need to know about where it is, etc. Oh, BTW, it's a dealer only item, IIRC and I got mine for $5 at a junkyard. Took me like 5 minutes to install. Very easy. BTW, Girls are just as capable of fixing cars as guys, it's just that most never choose to learn how!
