I had the same brake light problem with my 2000 Jeep Grand Cherokee. All was fine without the lights on.

However, when I turned the lights on, the middle brake light came and stayed on. When pressing the brake, the rear lights went totally dark and the middle (high) brake light intensified.

I found the solution here: I pressed the contacts in the rear/brake light socket and voila: the whole thing worked properly.

I had previously replaced the brake switch, cleaned contacts, talked to people at AutoZone and others. Nothing worked until the above simple solution took about one minute per side!

Thanks for the help.

My wife and I own a 2000 Jeep Grand Cherokee. She had the problem with her left rear door "quacking" when it locked.

It cost $200 or $300 to fix.

Also had the left tail light problem too. Everything is fine with no headlights, but when you have headlights on and step on the brakes, the left light goes out.

I followed the post from Jan 1 2005 and fixed it in about 10 minutes. Ultimately the ground contact in the tail light assembly gets pushed back and doesn't make good enough contact. I just pulled it forward so it was flush with the rim and the other contacts. Problem solved!

Because of the problems I have encountered with my 2000 Grand Cherokee, I will never purchase another Chrysler product again. The fact that just about every owner of the same vehicle has had all of the same problems, shows I just didn't get a lemon, but rather a victim of Chrysler's poor build quality.

That being said, here is a list of SOME of the problems I encountered, as did most of you.

Brake light assembly (had to replace whole assembly)

Infinity tweeter replaced

Door weather stripping (first driver side replaced, month later passenger side)

6 disc CD changer (still not working correctly)

Door lock Mechanism (first rear hatch replaced, now driver side is acting up)

Various Leaks (3 times so far)

Headlamp discoloration.

These are the ones I can remember.

My last vehicle, a Ford Taurus, while not as good looking was in 1 time in 6 years for a broken bracket that the dealer welded at no charge. That was it.

1998 JGCL Yeah - most of the above. Have replaced all of my door lock actuators. Started at driver door and moved around the truck till all were replaced. Now on my second cycle. Driver door again. My left side rear signal lamp problem stems from arching of the bulb contact. Used dielectric grease. Speed sencore, transmission surges after engine off, etc. etc. Warranty replaced rotors after 3 days of ownership.

Wish someone would make a better lock!

This is a beautiful site. I have ~140k on my 2000 Grand Cherokee Laredo 4x4, and have experienced many of these problems throughout the years.

The thing has eaten brake rotors like it's its job. I got some rotors from frozenrotors.com, which lasted longer, but they ended up warping too. I have just kind of learned to live with it.

I have fixed or replaced about 1/2 dozen window regulators. Most of the time they freeze up, which I eventually found I could fix by taking apart the motor and cleaning and re-greasing it. Sometimes though the plastic tab breaks off where the cable connects to. I look for good deals on eBay for the regulators.

I had done the fuel pump fix a while ago, which fixed the long cranking for a while, but it's back. Just living with that too.

My AC was not getting too cold, and I realized that the electric radiator fan was not working. Fixed that and a leaky water pump at the same time. That was a neat job, not!

At ~120k it started shifting funny, and would trip a check engine light when you passed a certain MPH. Took it to Advanced Auto to read the code, and it turned out it was my vehicle speed sensor, but this was sort of my fault, because I hadn't changed the tranny fluid in so long that iron filings had built up on the sensor's magnet, preventing it from sensing the reluctor wheel. :)

When I changed the oil the other day, I noticed both CV joint boots were split. Can't say this is unusual for a vehicle with this much mileage. I'm undecided yet as to whether to replace the axles, or just get new boots and grease.

The reason I found this site was because I got pulled over for a tail light out sometime back. I forgot about it until I went in for an inspection last week. I normally do 99% of auto repairs myself, but I figured they couldn't mess anything up replacing a bulb. It took a while, and when I asked what was going on, they said that replacing the bulb didn't do it, that they had to replace a fuse too. I called BS since I knew that each taillight was not on its own fuse, but I let it slide because they only charged me $15.

Last night, less than a week after the inspection, the Jeep died going down the road. Pulled over and it would crank fine, but would not start. Had my buddy tow me home, since I was only ~1/2 mile away, and when we got there, we noticed that the third brake light was on when the brakes were not depressed, and when I did press the brake, all three lights went out and took a long time to come back on when the pedal was lifted. So I guess I will take the tail lights apart and pry out the ground connector, as mentioned a few times here.

Also when we got home, the Jeep started right up again. I don't think the lights are related to the no start condition, but have also found here that the crank position sensor tends to short out, which would definitely do this, so I'll try replacing that, since it's an easy and cheap fix. I am hesitant to take the Jeep far from home now though. If I find it to be something else, I'll check back in.

Thankfully I have not had any quacking door locks. No door lock problems at all (knock on wood). If I do, I'll be retrofitting some universal actuators, as I have not seen them for less than ~$75 each. As long as the drive train holds together, I'm willing to fix all these problems that are more of a nuisance.

My 2000 Jeep GCL has had both brake light assemblies replaced, 2 door lock actuators and 2 window regulators, 2 rotors replaced. Now my latest issue: after leaving it at the airport for 2 days, I got in the Jeep, started it and hit the highway. On the way home I flashed my bright lights at a car with its lights off and all hell broke loose. The speedometer began to reel back and forth, the odometer began to flicker, and the brake and ABS indicator lights came on. When I got home, I turned the car off and attempted to restart it. There was no power at all, not even the interior lights when the doors are open, the power locks, etc. Battery has 12.5 volts, but no power to any systems. I haven't had much luck finding troubleshooting help on the internet so far. Maybe someone here can offer advice.
