Car electrical problem question

Recommended Posts

Ok, so here's the deal:

When my headlights are on a) my cruise control doesn't work (not a big deal) and b) MY BRAKE LIGHTS ARE ALWAYS ON (big deal).

So, my question is, how difficult is this to fix and approximately how much will it cost me? Any ideas are welcome. Thanks! B|

Sorry, I'm laughing at the thought of my Hyundai Elantra (2000, since you asked) with a trailer hitch. :D

Anyway, no, I haven't had any work done recently, but I also have no idea how long this has been going on. I knew about the cruise control about a month and a half ago, and if I've been driving at night with brake lights always on for that long, it's a miracle I haven't been hit.

So, hmmm, this is bad? That sucks balls.

*disclaimer* I am not a certified mechanic, so take my advice for what it is...advice, not gospel*

Quite likely a short somewhere....the problem (and expense) comes in tracking it down. If it were me (and I didn't have a mechanic friend I could sucker persuade to help me, I would start at the the brake light switch and work from there, checking both the brake light and rear marker light circuits. That, to me, seems like the most likely culprit based on no cruise (won't hold speed with brake applied) and brake lights constantly on.

I can't understand the laughter:ph34r: I put a trailer hitch on my 94 Elantra and pulled tent trailer through the mountains for family holidays for 4 years. Okay in 98 I upgraded to a van, but still the Elantra pulled a trailer (yes it was a really small tent trailer):)

What no hitch? I've got half the motor, and still have a hitch.... (see pic)

anyway... I know it sounds obvious, but check the fuses... When a fuse blows weird stuff can happen...

Hey, what about me??



Aww.. dude. I didn't even see your post. Credit the man in the white hat. I think it just might be adjustment of the switch is all.



de nada... was just pulling Kel's chain.

I don't think it's gonna be an adjustment... if it was, the brake lights would be on constantly, headlights or no. I'm thinking it's either in the brake switch (most likely), headlight switch (2nd most likely) or possibly a short between the marker lights and brake lights (remotely likely).

the grommet on the brake pedal that depresses the brake light switch has probably come off or the switch is bad. making the car cruise controll think that you are pushing the break pedal. hence the brake lights on and the cuise controll is cancelled when you hit the brakes..

kelly gimme a call and come by today. i will look at it.... sounds like an easy fix.

I once had an electrical short in the hatchback door on my old '93 Ford Mustang. I don't remember exactly what caused it, but I remember not being able to start the car. Just a dead ignition. The short was found in the wiring halfway between the lights on the hatchback and the hinges... Go figure! :S

or possibly a short between the marker lights and brake lights (remotely likely).



Actually, I would bet that's what it is. I that happen to me before: the salt and corrosion in the back of the car wore some of the insulation from one of my marker lights where the wire croses with the back of the brake lights with very similar results.

Also I had a short in the tailgate which prevented me from turning my car off (same vehicle as above). The only way I could turn the car off was by disconnecting the wire to the distributor cap. It was causing weird lights to go on and made a weird dinging noise whenever the short was made. It took me several weeks to track it down. I finally figured out it was in the tailgate when I noticed that when I opened / closed it, the short would usually happen.

I do believe marks is near the problem. If your brake pedal is thinking it's depressed it will cause the cruse to kick off. The switch on the back of the pedal linkage is adjustable. It may have simply became out of adjustment or is stuck in the closed position. This can happen very easily.

I guess I should have read closer, it only happens when the lights are on. If it was the pedal switch it would be doing it even in day time driving. You have a short causing your running lights to jump over to the break light circuit sending a false hi condition to the cruise control. I'd first check the attachment location of the hitch lights wiring harness to the car harness. Maybe some tape has unrolled or worn jumpering the circuit.

But keep in mind, it's only when my headlights are on. Does that still make sense?




then it is possible you put an 1156 bulb into an 1157 bulb socket. that will cause this also. and it would only do it when the headlights are on...

kelly.. your not going to get it fixed here... it is an easy diagnosis if you bring me the car... ive been doing this full time for 13 years.
