My first indication of a problem was the computer telling me my right turn signal was on and it was not. Upon investigating, none of the turn signal bulbs were burnt out. However the right front headlight was dim. I replaced the high and low beam headlights. A week or so later the problem has returned. When the head lights are off the turn signals work fine most of the time, but when the headlights are on the right side headlight is dim and the right side turn signal flashes fast. Also the high beams are on and very dim even though they shouldn't be on at all. None of the bulbs have broken filaments and there is no smoke or odd smell.

Any help would be appreciated. 2000 grand Cherokee, 4.0 L

Check if the headlight and the front turn signal have a common earth connection, and whether it is bad. That might cause these symptoms.

The previous owner had some PIAA fog lights installed and kept the lights when the jeep was sold. I traced all the wires and they weren't connected to anything but a ground and the battery. I think it was the same ground as the headlights. Anyway I removed all of the extra wires and the problem seems to have gone away. So good call on the ground problem guys. Thanks. bowdown
