No brake lights or blinkers- What could it be!!!

[sore]

I just noticed that my blinkers are not working, and my brake lights don't come on. The 3rd. brake light on the trunk does come on. Does anyone know what may be causing this???


Thanks,

Check all of your fuses. When that happened in my 95 it was a blown fuse.

all of the fuses look good.

The MF switch can do it. I'd check I/O's at that switch.

Good luck.

Where is the MF switch located, what does MF stand for?

MF switch = multi-function switch = your turn signal switch.

The tell here is that the high mount light works. That tells you that the BOO works (brake on/off switch). You can see where the rear left and right brake lights and turn signal lights all go through the MF switch (top left quadrant of this picture ).
Good luck.

Thanks, I go pick one up and give it a try.

Did you recently change something?

Whoa whoa whoa - don't go buying expensive parts. There's are other items that can cause the issue - that's why we do the testing at the switch. They're known to having connectors back out, etc. And that's a free 5 minute fix.

I'd first just want to check I/O's at the MF switch and confirm that the switch is bad before plunking down some coin on a 'let's hope it fixes it' situation.

I assume that people check things like bulb grounds, etc, or I recommend it down the line if your testing at the MF switch is ok (that you have output). So my suggestion about the MF switch was for diagnostics, not a 'fix'.

Just trying to save you some cash.

Good luck.

Gotcha! I haven't purchased it yet, i will do some testing later today.

Smitty, I havent changed anything recently, but a week ago the car would crank but not start. I turns out that it was the PIP. But before I replaced the PIP i did mess around under the dash because i thought it may have had something to do with the aftermarket alarm. Maybe i knocked something loose!

Thanks,

it was a fuse for me as well. mine would pop every time the car would move forward. it turns out the clutch pedal assembly had rubbed through the insulation on a wire under the dash and it would touch just enough to short when the car starts rolling forward.

i had a similar problem over the summer except it would pop a fuse and cause the 3rd brake to go as well. it turned out to be a wiring short near the clutch pedal assembly but the only other option was the MF switch and i woud highly suggest testing that... it will probably be the MF switch and is the piece with the blinker/ high beam lever attached to it. good luck!

It doesn't sound like you were anywhere near the cabling for your brakes/blinkers. I'm with Hissin. It is so easy for connectors to back themselves off because of vibration after a while. It has to be something very simple. I definitely wouldn't buy anything until you have or a friend that knows how to use a multimeter has gotten in there to make sure you have continuity and the switch is good.
