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?

1993 Suburban. Why do only the headlights and dome lights work?


So when you turn the key to on, no dash warning lights and gauges turn on? Did you check the fuses with a voltmeter or test light? With key off, some fuses would have power at all times-brake lights, headlights, horn- but with key on, all fuses should show power.

Just off the battery is the Battery Junction Block, where the power is distributed to various circuits through Fusible Links. These connect to battery power with eyelet connectors at the Junction Block-looks like 5 or 6 Links leading off the Block. Even the small wire from the battery to the Block is a Fusible Link, but if your headlights work, this main Link must be okay. One of the Links from the Junction Block would be to the ignition switch. If your ignition switch has power, you may have a bad switch, but you need to check if it has power first. If no power to switch, check the Fusible Links. The diagram I am looking at does not show which one it is, unfortunately.

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.

Need more info, is the vehicle battery draining down overnight and wont start in the morning?

Do you have a alternator gauge or light? Is the gauge at a negative or light on? Why do you think it not charging? If you say the battery is good..Give me as much information as possible, year, make, model, motor size...and I will do my best to get the problem solved for you. Thanks.

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.

Headlights are not working


You seem to have a stuck H/lmp relay, Taking out the circuit breaker only disabled part of the electrics,
If you examine the fusebox / Relay housing s (there may be more than one . You should be able to identify suspect relay (it will be warm to touch) . You may need to examine the Running lights / Dimmer H/lamp circuit if it had one. Putting an Amp meter across ( in line not parallel ) the not running vehicle will indicate drain from battery . There might be a slight arc upon connection but it will level out to near zero drain.
