Ok, I know one of the first responses is going to be check your brake fluid; please read before you post that.

This is on my JWT TT'ed, Haltech ECU 2005 G35, so it could be any number of things.

Here is the problem: The brake light is only dimly, sometimes flickers off and on. When I pull on the e-brake at a stop, the slip and VDC lights come on, as well (however, if I pull on the e-brake while moving, that doesn't happen). They stay on until I restart the car with the e-brake off. Also, when this happens, the e-brake light is on brighter than before, until I release the e-brake, and then it goes back to dim, but the slip and VDC lights stay on.

Since this happened, I changed the read brake pads, as well as the rear e-brake drum pads; I also changed some O2 sensors, but that should be unrelated. The brake fluid is at the max line, and the sensor plug for that is cleaned and made sure it is completely in. I also checked the front brake pads, and they are at about 75% new material left.

No SES light, nor any trouble codes, but with the Haltech ECU trouble codes, who knows how that interacts.

Any other suggestions?

 

Brake light switch behind the brake pedal.

 

Two switches behind the brake pedal; both switches seem to be working fine.

Also, I meant the brake light in the dash, not the rear brake lights, if there was any confusion.

 

I know. Mine seemed to be working fine, but I had those lights come on the dash.

The first time, my brake lights worked fine for a while, but a month later, they didn't.

Replaced switch, dash lights went away, brake lights worked.

Second time, dash lights on, but I didn't wait. Replaced switch, dash lights went away.

 

Any idea on the part numbers, and which switch was it, the lower or upper one? Or did you replace both?

 

It's around $30-35 from the dealer. Just tell them brake light switch.

The other is to disengage cruise control.

Well, that was easy to replace, probably the easiest thing I have ever done on my G. Unfortunately, it didn't fix the problem.

I think I found out what the problem is, though; the gasket from the engine compartment into the dash where all the wires run up near the battery has been damaged, and I think it has leaked some, as my carpet on the passenger side is damp, and as it dries more and more, I think the problem is decreasing and slowly going away. So, I need to seal that gasket better; time for some sealant.
