Question about 2000 Jeep Grand Cherokee

1 Answer

Headlights seem to drain the battery quickly... whats up?

At dusk I started up the vehicle and went about 2 blocks then the check gauges light came on... noticed my battery was in the "red" zone. I thought as I drove, it would charge... but slowly kept sinking lower... turned off the radio and heat... kept going down... finally turned off headlights (still bright enough to see, but getting dark) and it stabilized. By the time I got home (20 minutes approx) the battery gauge was on 9 (lowest level)... pulled into garage. I turned the car off, guess I shouldn't have done that... and then it wouldn't start back up. Any ideas? Suggestions?

I suggest you try one of those instant download manuals. My nephew bought one for me when my car broke and we could fix it all by ourselves with the manual costing $10. This website reliable-store.com is very good for this.
?Try it.

How do you adjust the headlights on 2003 for F-150


Park the vehicle on level surface if it is possible 15 feet from nearest wall. Open the hood and there will be 2 or three screws on top of the headlight assembly. One will move headlight left or right one will move up or down . Turn your headlights (prefer to be a dusk) so you can adjust your headlights on low beam way to get half of the light on wall and half of the light down on the pavement or concrete..Give a test drive and if thet seem to be low or high readjust it again.

Was fine started great then voltage hand went left abs light came on brake light came on dome lights came on head lights went off all panel lights went crazy blinking then jeep would not start without


Seems to be having problems with the alternator. Alternator itself can be bad, but also the voltage regulator, which sits inside the PCM (powertrain control module).
Don´t continue using with battery voltage around the 10V, because it will ruin your battery as well. Completely charge the battery with an external battery charger and let the alternator be checked out first.

This really an emergency I don't have money to fix my car right now. My car on the way to work started acting unusual. The dash lights stayed on while my gauges gave no readings and my radio completely...


The first thing you can do it to CHECK THE TERMINALS OF THE BATTERY< CHECK THE GROUDN CONNECTIONS TO THE CHASSIS.
If this seems corroded then clean and reset the terminals.
Secondly check the ECU, if the car seems to experience problems in the engine you must check the errror codes.
Finally the fuse box, relay box and the dash cluster must be checked for loose connection.

Could be either one or both get the battery charged if you have another vehicle hook up cables and see if it takes a charge for about 30 min DO NOT CRANK THE ENGINE FOR ANY REASON JUST PRESS YOUR REMOTE TO SHUT OFF THE ALARM SO IT DOESN'T GO INTO THEFT MODE AND PREVENT STARTING WHEN I WANT YOU TO START IT OK THIS IS VERY IMPORTANT THAT YOU FOLLOW WHAT I'M TELLING YOU OTHERWISE YOU WILL DRAIN THE BATTERY FROM CRANKING IN THEFT MODE ///////NEXT AFTER THE 30- 45 MINUTES OF CHARGING THERE SHOULD BE SUFFICIENT POWER TO START AND RUN THE ENGINE MAKE SURE THAT YOUR BATTERY HAS DISTILLED WATER IN IT IF YOU HAVE CAPS? ON IT BEFORE YOU START THE CHARGING PROCESS NOW FOR A SECOND OR 2 HONK THE HORN AND SEE IF YOU HAVE HEADLIGHTS A LOUD HORN AND STRONG LIGHTS WILL SHOW A CHARGE IF YOU HAVE A VOLT METER CHECK FOR VOLTAGE BETWEEN 12.5 TO 13.5 VOLTS IF YOU HAVE THE VOLTS THATS GOOD NOW START THE ENGINE IF THE BATTERY LIGHT IS ON IN THE DASH THE ALTERNATOR MAYBE BAD CHECK FOR VOLTAGE AGAIN WITH THE METER IT SHOULD BE 14.4 IF YOU DON'T HAVE A VOLT METER QUICKLY DISCONNECT THE BATTERY CABLES WHILE THE ENGINE IS RUNNING IF IT DIES THE ALTERNATOR IS BAD THE MOTOR SHOULD KEEP RUNNING OFF THE ALTERNATOR POWER THAT IT IS GENERATING SO GOOD LUCK I'M SORRY IF I LISTED THINGS OUT OF ORDER I'M A TAXI MECHANIC IN NYC WITH 50 YEARS OF EXPERIENCE BUT I'VE BEEN WORKING FOR 16 HOURS TRYING TO GET CARS RUNNING FROM VERY HEAVY RAIN HERE TODAY THE DRIVERS AREN'T SMART ENOUGH TO SLOW DOWN WHEN GOING THROUGH FLOODED ROADS AND HUGE PUDDLES AND I'M BY MYSELF THE OTHER 2 GUYS ARE OUT WITH THE SUPER BOWL FLU SO I'M TRYING TO HELP YOU ON MY LUNCH BREAK AND IN BETWEEN VEHICLES SO PLEASE READ EVERYTHING FIRST PUT DISTILLED WATER IN THE BATTERY FIRST IF YOU CAN OTHERWISE CHARGE IT AND DO THE REST DESCRIBED OK GOOD LUCK STEPHEN
