no 23 in the box under the hood

 

OK, now I really do feel like the class dunce

I can't make head or tail of the PDC diagram in the FSM, possibly because it's for a 95, but possibly because I just can't read it right!

Here's my PDC - could you tell me which of the fuses no 23 is?

 

OK, I'm just going to swap the lot I can always test them and keep all the good ones as spares.....

 

thats no the box i was looking at i started a new post for the fuse local

 

as posted no2 is the fuse it powers tai lights and hazards you stated they are working id get a switch and replace it

 

I actually had a Monte Carlo before where the brake lights wouldn't work and it ended up being the Turn Signal Switch. If you tested the Brake Switch and it tested good I would not waste money buying a new one.

 

Well let me just say that I REALLY appreciate the time that you're putting into this. It seems to have become a bit of a mystery and I'm really glad that you're helping me out. Thank you!

I've got a second hand brakelight switch in the post. It is from a 96 so I hope it is the same. I'll soon know. I've also got a bucket load of fuses arriving from ebay so I'll at least be able to test/swap out all the fuses to see if there are any faulty ones.

I have a meter so I'll get my head back under the dash and see if I make any sense of the brakelight switch. From the FSM, the switch is open when the pedal is up, and closed when the pedal moves so I'll try and make three pairs out of the six contacts on the connector and test 'em.

I think my gut is telling me fuse/short rather than the switch at the moment. The brake lights did not come on when I shorted the blue/pink and white/white tan connectors.

edit: I just noticed the question about the colours on the other switch. I'll just go have a look.

nope, can't find it... I'm at work and can't really take the trim off in the car park! I can't feel it either so maybe that's another change they made between 95 and 96?

 

the ony reason i say the switch is because you stated you flashers work and tail lights in the other pst it was shown that the fuse feed all these and two of the three work

 

did you ever check the bulbs

 

I don't have a wiring diagram with me but the brake light should send the power to the turn signal switch then back to the brake lights, when I get home I'll see if I can find it... adobe's been acting up on my computer though, so if someone else can confirm, go for it.

You don't have to replace all the fuses if you have a multimeter, check for continuity between the two posts, if there's continuity the fuse is good, if not the fuse is bad. If all the fuses check out fine, you should be able to rule out a short as it *should* cause a fuse to blow.

 

Here are the diagrams for the brake lights. If you are getting power to the brake switch and the brake switch is good it has to be the turn signal switch. I can not believe someone would tell you to replace a switch that after you jumped the wires and the lights still did not work.

 

More updates.

The bulbs are definitely good, I tested em with a 9V battery and they glowed (not bright but it was only 9V).

When I get my brakelight switch I'll just plug it into the loom instead of the existing one and hopefully eliminate the existing switch from the equation that way. It was only £5 so I'm not worried about that right now

Now the turn switch... that's interesting. Is there a way for me to test it on the Jeep?

Edit: I'm not sure that it will be involved... this being a RHD Jeep it doesn't use the brake lights as turn signals.

 

Top advice, I'll be out there with a torch between my teeth again tonight! I wish I had a headtorch :/

 

On my car I had it was weird because sometimes my brake lights would work if the turn signal was on. It took me about a week and some searching online to find out the 2 are even connected. Who would honestly think your turn signal switch has something to do with your brake lights? I didn't but that is what it ended up being. I not finding a test for a 96 anywhere. I hate to tell someone that is definitely what it is and have them buy it and they still have the same problem. If you have power on both sides of the switch, what else could it really be?

 

SOLVED!

and I am officially an idiot

It was the bulbs after all. I didn't realise that the top set of bulbs in the rear were dual filament stop and tail lights. So.. when I wanted to test the bulbs, I put the headlights on so I knew which ones NOT to test.
So, the tail light filament was working on both sides, but the stop filament was broken on both side.

It was the bulbs.
the damn bulbs all this time....

Thank you for all your help, I'm really sorry to have wasted your time! I'm posting this up incase someone as clueless as me has the same problem in the future!
