Chevy s10 multiple fuses not working.
I Was driving and ac stopped working Wondering
Why My Ac Compressor Wasn't Engaging. Checked
Fuses And Found 11 Under Hood Fuses Not
Working. Is This Cause Of Ground Or Do I Change
All 11 Fuses?? Don't Know Where To Start
Some fuses are hot all the time, some go hot with key on. Check-em both ways, use a test light to check for voltage at fuse.
If the fuses are blown you need to change them. If you have that many bad fuses all at once I suspect wiring damage or a serious short.
How do I find short?
How do I find short? Those fuses are with car on.
Are the fuses blown? If not, maybe problem with fuse box? You have diagram for compressor relay, which fuse no voltage, either one, both?
It doesn't appear to be blown. Just doesn't light up when testing with light, with car on. I don't have a diagram for compressor.
The horn 15A, VEH B/U 15A, TRCHMSL 10A, VECHMSL 10A, HDTMIR 10A, CRANK 10A, AC 10A, RT TURN 10A, LT TURN 10A both sides of all fuses have no light when tested except ac 10A one side of fuse lights up
When car is on
Checking the fuses, your checking with fuse plugged in? Your touching the bare spot over each fuse leg. If one bare spot is hot and the other isn't something wrong with fuse. The horn fuse goes hot when horn relay is energized, according to my info. The crank fuse goes hot with key in the crank position. The turn fuses go hot with key on. Note the diagram, see those top fuses, check fuses and check for voltage. They supply voltage to ignition switch.
