I have a 2000 Grand Cherokee that the blinkers have stopped working. I located the flasher under the dash on drivers side and replaced it twice with flashers from a salvage yard. Still no turn signals. Emergency flashers are working. Everything points to the flasher, but I thought the odds of two used ones being bad were slim. I am trying to test the flasher. Based on the wiring diagram, Pin1 is 12v+ from battery to operate emergency flasher and Pin 6 is ignition switch voltage for turn signals. When I tested the socket under the dash, I have 12v on the Pin 1 location with key on, but only 3.4v on Pin 6. Does this mean my BCM is bad? Should there be 12v on Pin 6? While the flasher was removed, I applied 12v+ to Pin 1 of the flasher and when I touch the ground to Pin 9 the coil engages (Hazard Lights). I applied 12v+ to Pin 6 and the ground to Pins 7 and then 8, but the second coil does not engage. Are 2 separate 12v+ required to test the flasher? Any help would be appreciated as a new flasher is $50 bucks! I hate to buy without being sure that is the problem.

First off I have a 2000 Grand cherokee limited with the 4.7 v8. Just recently I think I blew my head gasket (maybe cracked head or something) but I was burning coolant until the motor got warm then it didn't smoke. I was told it was okay to drive just get it replaced soon. I had a family emergency and HAD to drive it on a 4 hour trip. It ran fine on the way here nothing wrong and I parked it and didon't do anything out of the abnormal to it. About 45mins later I went to start it up to drive and it was running way hotter than 210 and burning coolant the whole time. 210 is halfway for me and it was at the 3/4 mark before I got it parked and pouted water into the coolant resoviour. Waited for it to warm the watter so I didn't run cold water through a hot motor or was about an hour. I started it back up and it was about 150 and it smoked like normal and got up to 210 when I was driving (about 2miles) and when I stopped at the house it started overeating fast. I don't know if I can make it home can seine tell me what the problem could be, I'm thinking maybe either thermostat or water pump. All help is appricated.

2000 Jeep Grand Cherokee 4.7 v8 replaced crank after a bearing went down. Ran great before replacing the crank. Replaced cpu iac valve and tps. Dies when accelerating off idle but will run fine if you can get it above 1500 rpm. What am I missing?

All was great, went to fill up, got in started her up. Right as i pull off it starts to ride rough, with hesitation,
Sputtering, n LOUD. Correct gas was
Pumped. Also, check engine light came on, not a steady light but a blinking one. Since timing got worse with each start til it completely stalled
And would not start back up it would turn over you can hear the engine turn over but it would not start. Crankshaft
Position sensor replaced, after, we could get it to start again and stay at a idle but rough n noisy ALMOST as it was before but alittle better I suppose. PLEASE HELP, ANY IDEAS
All i did was fill her up.

I tried giving it gas and it still wouldn't stay running. The alarm doesn't work either. I tried taking out the computer and sanding the grounds out but still nothing. I'm guessing it electrical. Gages won't move, it'll start but won't stay running. Only runs for a good 2-3 seconds. I'm not sure.

It will sit and run in idle can't rev the engine

Anyone else have a problem with short circuits in the brake lights?

What's wrong with my jeep grand Cherokee Laredo? My jeep had a leak in the radiator and then the engine started over heating. Replaced the radiator and thermostat took engine apart cleaned engine and replaced the head gaskets put it back together and tryed starting it well it started but there's a knocking in it and the piston isn't in the best of shape and it seems to work but it doesn't look like the sound is coming from the piston and it's still overheating I'm not sure what is wrong with it and i don't want to take it to a mechanic because I would like to fix it please help me figure out how to fix my jeep.

I just got a tune up, the serpentine belt replaced and a new fuel filter put on.

Codes: 303, 203, 158, 320! My cars symptoms are like what is described in many forums as being similar to both crankshaft sensor problems and camshaft sensor problems. My mechanic told me we should replace the camshaft sensor first. But the code referenced by ODB was crankshaft 320 not camshaft. In looking at all these codes together. Which would you suggest to change first?
