Problem Description and Possible Solution
Electrical issues that are difficult to diagnose—and sometimes intermittent—are typically due to ground wiring issues. The most troublesome ground locations are under the battery or at the engine.

I have changed the starter and alternator and my car still won't start what else could be the problem
Door locks stop working intermittently. Key always works but alarm doesn't always initiate. Remote for locks doesn't work and it isn't just due to a bad battery. Unlock button on driver's side door needs to be held down forcefully for a long time to get other doors to unlock, sometimes it won't work until the car is turned on. This is driving me crazy!
Something is staying on after removing the key and runs the battery down. Have had it checked on machine and couldn't pin point problem since then have replaced the battery, but it's still running something when it should be asleep.
Light for hood up is staying on, windshield wiper fluid will not spray and wipers sometimes won't work, also having problems with car alarm going off.
headligh low beam went out . replaced switch. not it. now the lowbeeams on in the DLRunning light position . in the low beab position the headlights work but the dash board doesn't light up. RRRRRRRRRRRRRRR
The main source of my problems was the ground located under the windshield wiper cowling. Remove the cowling and there is a bolt with 3 grounds running to it. Remove and clean the grounds and it should help. I was getting a Cam Sensor Code. Car actually seems to run better too!
my windows all quit working, and my abs and cruise dont work as well. im assuming its wiring since they are notorious for the crappy job but i cant diagnose the problems exactly.
Windshield wipers do not work unless lights are in on position and high beam is held on, and then only drivers side works. Headlights do not work except when held on. Cruise control does not work. Air (heat or AC) blows on low in every position (0-4).
Replaced multi function switch (cruise, high beams)-problem did not resolve.
Sure this is a ground issue, but can not find where the ground is.
a/c fan does not come on when a/c is on. both fans have electrical power. also when hooked up direct both fans work
2.5 liter 2005 has had repeated intermittent engine light issues
I have a lot of trouble with fuses and electrical under hood. Trouble finding problems and still haven't fixed all.
electronic keys won't work, dash light stays on when shut down, battery drains, running light system intermittently flashes, NO solution yet
problem with cluster, first erratic speed, gas gauge, no light or gear indicator.
worked ground under battery and sensor, change top sensor under windshiled wipers.
now all work and are right w. But work only intermittently. No answer for that.hen they work
Cost me a new fuel line system to realize it was a bad ground and that my fuel line was just fine..
When I use the highbeams a different light will shut off and the indicator on the dash comes on saying I have a light out. Always 2 seconds after turning on the highbeams the a tail light goes out or the license plate light sometimes its the amber light on the front near the headlights. Uppon turning off the highbeams if I turn the headlight on and off three times whichever light went out comes back on and the indicator on the dash goes off.
I had the same symptoms. It was a loose cable. Remove main battery cover. Remove the BLACK ground cable on the right side of the battery with 10mm socket or wrench. You will see a smaller box that the RED battery cable feeds to, with 5 smaller wires feeding out the back. Flip open the lid on the smaller box. Check the 5 smaller wires and make sure the connections are TIGHT with your 10mm socket or wrench.
The first wire on mine was loose. Vibration from the engine would cause an arc and stall the engine.
Door locks,electric seats,lights etc
car wont start if extra ground wire not attach to the enjin or body. wont swich off if extra ground wire is not disconnect. i check all the ground attachments and clean it
