1997 Buick Lesabre Passenger-Side Fuse location, A/C fuses and horn fuse
A friend recently acquired a 1997 Buick LeSabre, and until a few days ago, the air conditioner was blowing cold air. The next day, it wasn't and, we being no experts, think it may be a blown fuse. (We check the least expensive probabilities first.)
A second issue is the horn, which never worked from the start, and we suspect that to be a fuse as well.
I don't know the specific model of LeSabre, but it has a fully automatic climate control, power windows, automatic rear-view mirror, driver-adjustable outside mirrors, too.
There are two climate control panels described in the owner's manual, with the first having slider settings, the second having an LCD display and push-buttons. We have the latter.
You can set the desired air temperature, and hit "auto" and it controls everything to try to reach and maintain your set comfort level. It senses the sun beating down on one side of the car and compensates with more cooling on that side. it senses outside temperature, which shows up in the LCD display screen, together with current settings.
It is a four-door hardtop model.
The manual is in his car, not here for me to reference precisely, so I will do my best from recollection.
Turning to page 6-59, the book is describing the in-cabin fuse locations. There are two, one on the driver's side, under the instrument panel, left of the steering column, photo included for easy identification, and a list of the fuses found there.
The second fuse block is on the passenger side, under the instrument panel, under, on, or around a relay-something, and a list of its fuses is included in the book.
The right end of the instrument panel is from top to bottom, the radio, the climate control panel, an ashtray. That is over the right side of the drivetrain hump. Just right of the instrument panel display is the passenger airbag, and below that, the glove compartment.
Open the glove compartment, there is an oil reset button or switch, and a trunk release button.
The underside of the instrument panel is a bunch of covers with floor vent duct openings, no sign of fuses or relays there, versus over on the driver's side, on the underside left of the steering column is the pictured fuse cover. Looking forward and level, at this fuse block, there are red and blue items peeking out at you.
Over on the passenger side, there is, under the glove box, a rectangle that has some bolt heads on a black wavy surface looking out at the passenger's knees. There was once a nameplate there, most likely, a piece of trim that has long since disappeared.
I wouldn't think we need to pull down the ductwork covers to see anything relating to fuses, but I am no expert. I do know they can be a bit of a pain to put back in after they are removed.
Open the ashtray, and find the cigar lighter to its right. Poking around behind the removed ashtray has me encountering wires, probably for the lighter, together with its inline fuse holder.
Poking around under the ashtray, I find a round hole in the hard plastic, this side of the soft-plastic, loose-fitting ductwork covers that occupy the remainder of the instrument panel, forward to the firewall.
There I encounter a couple of long bolts coming from the firewall, about level with the loose-fitting covers. I push the covers up and see the bolts.
In this passenger-side fuse block that we can't locate, is the fuse for the horns and the fuse for the A/C Programmer.
Now, since there is power to the display, and the display shows the current outdoor temp, indoor temp setting and other settings, everything about the display is working, this fuse is maybe good, and a fuse under the hood is out to cause the A/C to fail to run.
Very likely we need to find this passenger fuse block to replace the potentially blown horn fuse and check the possibly good A/C fuse, but need to locate the engine fuses to reinstate the A/C.
I hope I have given enough of the right details to help the party that proposes to answer my questions. Thank you.
