I've read through the forums, was very intrigued by the brake light issues, and might have a little insight into this issue.
I understand the tailight faults, the grounding issues, and the possible broken wire problems in these circuit, but, was very curious about all the outcomes.
Let me first say that the problems with the ESP/BAS, and ant-skid lights suddenly coming on did NOT begin this journey, but, something a little different. Back in October, when applying the brakes one day, the above mentioned dash lights came on, along with a circuit "bleed" to my left signal light, which means that sometimes, when I applied the brakes, the left signal light, on the dash, would come on faintly, and intensify, the harder I pressed on the brake pedal!!
OK, obviously, or,by chance, I thought right away...aha, it's the brake switch, which under normal circumstances, is an easy in and out fix.
I order a new brake switch, aftermarket, it arrived, installed it as instructions portrayed, and voila, the ESP/BAS lights went out after resetting the engine light, the left signal light did NOT bleed on, BUT, I had NO BRAKE LIGHTS!!. So, I thought, aha, it's a faulty switch again, but, I went through the circuit issues, followed them from front to back, and no remedy.
So, I sent the defective switch back, got a refund, and replaced it with an OEM, by Mopar brake switch, and though the ESP/BAS lights did NOT come on, and the left signal light did NOT come on, I STILL had no brake lights AND, the SEL light came back on...what the !!!!
I went to our local Canadian Tire store, they had one in stock, so, bought it, took the old one out, the dealer refused to refund a "used" electrical part, even though it was installed for maybe 10 minutes.
I installed the one from Canadian Tire, and AGAIN, had the same issue as above....NOW I'm getting stupid mouthed, and this is getting ridiculous...so, went through THE WHOLE wiring harness front to back, looking for obvious/unobvious wire breaks/frays, and found NONE...had full conductivity, front to back. I was very frustrated!!...put it all back together, STILL, no brake lights.
I pulled the Canadian Tire supplied switch, took it back, they replaced it no questions, and thought, ONE MORE TIME, then I'm REALLY gonna ***** to Chrylser about the dangers of their design flaws after reading all your posts about these problems.
I installed the new switch AGAIN, for the 4th time, reset the ECU, and VOILA, everything works, no dash lights on, brake lights all work properly, and the issues have disappeared.
I can tell you from personal experience, that just because you've replaced the brake switch, and it's NOT solved the problem, DOESN'T mean that it MUST be some "other" problem!!
It's all working now.....I'm almost giddy!! Now, it's "giddy up jeep time once more!!"
