Where can I look to find specific meanings of the abbreviations in fuse box?.

Thank you, so I'm not even sure if the 3 problem issues I'm having with my 2002 Buick Le Sabre have a fuse relay thus the reason for question. My first instinct when troubleshooting things electrical, I start simple check for a bad fuse/relay. But I'm stumped. Unfamiliar with so many abbrev. I so appreciate your help. So the 3 problems: a) cooling fans, b) horn, c) wiper fluid. Felt strange, all happened in close proximity. Horn is new honked twice..? Thanks again Janice .

My main issue is cooling fans tho, I just got a new tranny' put in him a week ago. Ouch, $$$. I deliver newspapers, that's my job. 365dys yr. for the past 11yrs, drive up to 100 miles daily. Since getting car back, he's been overheating and cooling fans aren't kicking on. It's imperative I fix this by any means, if it's a fuse...yaw effin wuhu. Thank goodness the fans are easily accessible too, should they need replaced. Janice

Hi, The two cooling fans operate when commanded by the powertrain control module via 3 relays which allow one or both fans to operate at low or high speeds. Each fan has a 30 amp fuse in the underhood fuse block - Fuses 46 and 47. The relays are on the underhood fuse block also. A diagnostic tool is used to monitor processor commands - are the fans commanded on? If so, are the fans on? If not, are the fuses blown? If not, are the relays good? Alternatively, when the fan should be on, is there power at the cooling fans? The trick there is - no guesswork; testing is required. If the engine coolant temperature sensor, for example, is not reading properly, the processor will never know the engine is hot enough to turn the fans on in the first place. Here again, testing is needed. For the washer fluid, is there power at the washer pump? Again, testing is needed. The washers themselves do not have a specific fuse; if the wipers turn on, the fuse in this circuit is not in question. Or - is the washer pump working and there is a fluid leak? Or, is the wiper switch not engaging the washer system? For the horn, fuse #25, a 15 amp fuse can be checked. Other than that, check wiring and grounding. I appreciate the desire to check simpler obvious things, but there really aren't any easy solutions here that can be done efficiently without performing needed testing.
