Reported cause
Turned out to be rodent damage in the harness leading to the taillight.
Leading evidence: 'rodent damage in the harness leading' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'rodent damage in the harness leading' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Disconnect battery' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Bought new fuse disconnected battery and then new fuse installed it�s blown.

Thanks Mike for helping to clarify...That phrase is commonly used in Automotive Shops in the South when Technicians get confused during testing sequences and need to "start all over again"...Its a Southern thing ...

A $5 harbor freight multi meter can easily test the switch.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

( and the new brake-light switch did not fix that)...
I changed brake pedal switch, now I get code 4304 no signal to brake lights. And fuse is blown. Bought new fuse disconnected battery and then new fuse installed it�s blown. Anyone have this issue. Thanks in advance
Right....you may be asking the wrong question....
A better question might be .." why is my fuse blowing ? ( and the new brake-light switch did not fix that)...
If true then you did something wrong during the brake-light switch install......as we say in the Shop...you need to "lick your calf all over again"...
Maybe you installed the wrong switch ? Check the part # ...
correct I have a new switch on the way. But first I�m testing old switch, replacement switch and new switch prior to installation. We will see I�ll update for others with same issue. Is disconnecting battery necessary? Thanks
I had an issue with the driver side brake light. No issue with the fuse and no codes, but no voltage in the brake light socket. Was hoping there was a break in the harness for the taillight and bought a replacement, but no joy. Turned out to be rodent damage in the harness leading to the taillight. Got that fixed and all works now.
thanks for suggestions.
No fuse didn�t blow with switch unplugged and brake pressed.
waiting on new switch today� hopefully I�ll have time this weekend.
Thanks again!
What happens if you remove the wires from the switch and jumper them? Effectively closing the loop. If the fuse still blows, that rules out the switch.
Maybe my question wasn't clear...
Just trying to determine what side of circuit blows the fuse. Fuse side or brake light side.
So, to be clear, does fuse blow with switch plugged in and only once brake pedal is depressed...? Or does fuse blow as soon as switch is plugged in..?
Its really doubtful the switch itself could blow a fuse unless the connector pins are bent and somehow shorting out..? Or connector is plugged in wrong.
I like to test switches and confirm they're faulty, before being a parts changer that maybe doesn't even fix the problem...
A $5 harbor freight multi meter can easily test the switch. Switch either makes or breaks the current. So there should be no continuity on brake pedal switch's 2 main terminals till its pushed in. iirr 2 sets of terminals, 1 is n/c the other n/o. If you test both and they make and break, its not the switch causing lights to not work.
IMO, if fuse blows when pedal is depressed, the most likely suspect here is your tail light wiring or bulb sockets shorting out.
And if both lights were effected, its the wiring before they split to each side...
I will follow your instructions. And follow testing. I�ve owned car since new and is garaged. Had hot rods to drive daily. Stuff gets old, like me.. haha. Thanks again
