so yeah now my drivers side footwell cathodes (2)
stopped working, i don't understand why. my passanger side works fine and my vents but the two under my side wont. the transformer still lights up. im pretty sure i didn't blow them?
idkkk

 

try switching the cathodes..if the transformer still lights up it might not be that, but still a possibility..so try switching the cathodes around, if the same cathode doesnt light up then its not the transformer its the cathode itself

 

both work on my other transformer its definitely that, real cool lol

 

Switch to LED..
