Well I brought new bulbs for my CRX the other day figuring it was blown bulbs. I replaced them and I cant figure out why my brake lights arent working. Where should I start diagnosing the problem at first?

 

fuse?

 

which fuse would it be?

 

the brake light / tail light fuse

 

if you don't have the underdash diagram on the fuse cover, then just pull 1 fuse at a time, checking to see if it is blown, and if not then put it back where it goes before moving to the next one. if you find one that is blown then replace it with the proper amp fuse and see if that fixes your problem.

 

ok thanks for that I am going to do that right now. If I cant find one blown what do you think it could be after that?

 

well the way i do it is with a test light u ground the test light and u touch the little metal part of the fuse on top with the test light probe if the test light lights up on both sides then its good save me a bunch of time

ps the key has to be on the 2nd position for some of the fuses to light

 

Well ive checked all the fuses and they seem to all be ok even tried changing the fuse for the tail lights. I had a friend mention a brake switch. Where could I find that.?

 

could be the brake switch on the peddle or some corrosion on the elec

 

Corrosion on the elec? whats the elec?

 

by elec I think he meant electrical wires.

 

the switch could very well not be makin contact. Also there are ground in the back if u take the covers down and plugs to remove the tail lights w/o takin the bulbs out. check that out that might be the prob
PS-- look under the hood for any fuses in the fuse block for the tailights

 

I might have to check the wires to see if they have ground. My fuse box is under the dash. I have a B16 swap in the car also. I dont see a switch on the brake pedal so I am assuming thats the problem but im not ruling anything else out. I just hope its not wiring

 

by the sound of it its probably wiring... are your blinkers and reverse light working? your wiring harness might not work with your swap ive seen it happen before (crx hf w/ h2b swap)

 

Are you sure? its above the pedal itself attached to a "tab" that lines up with #8 in the pic below

 

Thanks Grog That Diagram was a life saver Buddy. And to JDMED3 yea my reverse lights and blinkers work. I just hope it isnt a wiring problem because I suck at wiring.

 

update on the issue?

 

I didnt get a chance to check anythig out today but as soon as I do I will keep u updated JDMED3 tahnks for checking bro
