SOURCE: tail light/dash lights out

You probably have a bare wire at the back of your car that is shorting out on the frame, or against another bare wire.

SOURCE: no dash or radio lights

MAKE SURE THAT THE DIMMER SWITCH IS NOT TURNED ALL THE WAY DOWN. IF IT CHECKS OUT, THEN CHECK THE FUSE FOR THE INSTRUMENT PANEL LIGHTS. IT SHOULD BE UNDER THE DASHBOARD ON THE DRIVERS' SIDE OR TO THE LEFT OF THE AIR DUCT NEAR THE DOOR HINGE. HOPE THIS HELPS. PLEASE KEEP ME POSTED. THANKS FOR AN HONEST RATING AND FOR USING FIX-YA. GOOD LUCK

SOURCE: dash lights go off intermittently

I'm no expert, I recently purchased a 2003 vibe. I noticed the automatic headlight's sensors can be super-sensitive, about an hour hours before dusk they'll kick my headlights on (when the sun is still shining!), or sometimes when I go into an underpass, and then sometimes they'll realize it's light enough and turn themselves off. This would cause your dash lights to go to the 'headlights on' mode and turn the headlamp signal on, the intensity is controlled by the dimmer/dome light control on the left side of the dash. Check to see if the dimmer is down too far, as this could cause the lights to dim when the automatic headlights turn on. It's also possible that the dimmer is not working, thus no power is getting to the dash lights through the dimmer. Try testing it by starting the car in daylight, then manually turn on the headlights, then adjust the dimmer. Like I say, I'm no expert, just guessing because I've noticed it happen similarly on my Vibe, but my dimmer was at half-way, as I like it for night driving. Someday, I'd like to disable the automatic sensors and DRL.

There are two possible cause of dim display.

On the deluxe trim level of the Impala the is light sensor. When the sensor mis-calibrated the light will not be at the level you want.

As a test,use a small flash light and aim to the sensor and see is the circuit act according it.

====
The dimmer light is a VERY CHEAP component. I will glow it out with compress air 1st. Turn the dial back and forth 20-30 time in rapid motion will help remove unwanted carbon,

===
Use a eletrical contact cleaner to clean all contacts.
===
Is the headlight in OEM specification?

After market headlights may draw more amperage and cause low power for smaller bulbs.

Right low beam headlight does not come on but my right turn signal will stay even tho i diddnt turn it on. If I cut on my high beams the rurn signal cuts off. Whats wrong? Helo


It could be the lamp control module !
Headlamps
Battery positive voltage (B+) is applied at all times to the lamp control module (LCM) through the underhood fuse block HDLP fuse.
When you place the headlamp switch in the HEAD position, the headlamps input to the LCM is grounded. The LCM then applies battery positive voltage (B+) through the underhood fuse block HDLOBML fuse and HDLOBMR fuse, which feed the left low beam headlamp and the right low beam headlamp respectively. When you activate the headlamp dimmer switch by pulling on the multifunction lever until the switch clicks, the high beam input circuit to the LCM in grounded . The LCM then removes battery positive voltage (B+) from the low beam headlamps and supplies battery positive voltage (B+) through the underhood fuse block HDHIBML fuse and HDHIBMR fuse, which feed the left high beam headlamp and the right high beam headlamp respectively.
Check this fuse in the left under hood fuse box first. HDLOBMR Fuse 18 10 Amp. RH Low Beam Headlamp . If the fuse is good check for B+ voltage with the low beams on . Use a test light or volt meter . If you look on top of fuse there are two metal tabs ,check there for B+ voltage , If no B+ voltage the LCM - lamp control module isn't supplying any .

98 cad deville headlights stay on headlight & twilight sentinel switch is off along with the ign. i'm stumped can you help. Ted


Did you check the high/ low beam headlamp relay ? Stuck contacts in side relay .Plus headlamp relay an DRL relay .All are located in the underhood relay center .
The headlamps are controlled by the body control module (PZM). The battery positive voltage (B+) is applied at all times through the HDLPS fuse at the switch side of the headlamp relay via CKT 340 (ORN).
Battery positive voltage (B+) is also applied at all times through the RADIO/PHONE fuse to the coil side of the high/low beam headlight relay via CKT 40 (ORN/BLK). Both relays are controlled by the PZM at separate output cavities.

When the headlamp switch is in the HEAD position, the instrument cluster headlamp switch input is grounded through CKT 10 (YEL) and the headlamp switch. The instrument cluster sends a request through the Class 2 serial data line to the BCM in order to active the low beam headlamps. The BCM supplies positive battery voltage (B +) to the coil side of the headlamp relay via CKT 352 (WHT). The coil receives ground through the headlamp switch via CKT 10 (YEL). The coil of the headlamp relay is then energized, closing the switch contacts. Battery positive voltage (B +) is then applied through the high/low beam headlamp relay via CKT 1346 (LT BLU) and the L HDLP LO fuse and R HDLP LO fuse via CKT 12 (TAN) to the left and the right low beam headlamps respectively.
This may sound pretty complex .

Lo beam headlight on right side not working.


try using a voltmeter on the plug for the bad headlight. turn on the ignition, and turn the headlight switch. If the voltmeter shows no voltage, then either your switch or the wiring leading to the headlight has gone bad. check wiring for breaks to headlight first. good-day! if no voltage.

Dim headlight one side


Check voltage to lamp assembly. Could be a relay, a bad wire, or a bad connector. Since one headlamp works correctly, the switch assembly probably works. Without a wiring diagram. I can't tell whether the headlights get power directly from the switch or not... Time to buy a manual.

When you turn the headlights on everything works but the headlights. If you hold the dimmer switch in the brights will come on. When you let it go the lights go out


Have you tried to change the headlights?

REMOVAL & INSTALLATION Sealed Beam NOTE: If vehicle is equipped with headlamp doors turn the headlight switch ON. Open the hood and locate the power distribution center. This center is located in the front of the left front strut tower. Remove the cover from the center and remove the Headlamp Close Relay. This will prevent the headlamp doors from closing to provide easier servicing. Turn the headlight switch to OFF, then perform this repair.
  1. Remove the headlight bezel.
  2. Unhook the spring from the headlight retaining ring if so equipped.
  3. Unscrew the retaining ring and remove it. NOTE: Do not disturb the two long aiming screws. Conventional and Halogen headlamp sealed beams units are interchangeable in pairs, but it is recommended that they not be mixed together (one halogen and one conventional). It is fine to upgrade from conventional bulbs to halogen, but do not change from halogen bulbs to conventional bulbs, especially if the vehicle came equipped with halogen bulbs.
  4. Unplug the old sealed beam from the engine electrical wiring harness.
  5. Extract the old bulb from its mounting bracket. To install:
  6. Connect the replacement bulb and install it into the receptacle (check operation of headlight before completing repair).
  7. Install the retaining ring and secure it in place with the retaining screws. Connect the spring.
  8. Install the headlight bezel.
Aero Headlamp Aero headlamp systems use replaceable halogen bulbs that are mounted in aerodynamic, molded plastic lens reflector assemblies. NOTE: Lens fogging is a normal condition and does not require service, as moisture will vent from tubes behind the lens on Aero headlamp-type system. EXCEPT PREMIER AND MONACO It may be necessary to remove the entire headlamp assembly if enough access cannot be gained otherwise.
  1. Locate and remove the wire connector behind the headlamp assembly in the engine compartment. It may be necessary to remove certain items in the engine compartment to gain access to the bulb wires.
  2. Rotate the bulb retaining ring counterclockwise 1?4 turn and remove the ring, bulb and bulb holder from the lens assembly. The bulb holder has alignment notches. NOTE: Do not touch the bulb with bare fingers or any possibly oily surface, since reduced bulb life may result! Fig. 1: To remove the light bulb, first unplug the headlight electrical connector, then . . . 86726p13.jpg
    Fig. 2: . . . remove the light bulb socket retaining ring 86726p14.jpg
    Fig. 3: Rotate the light bulb socket 1?4 turn counter-clockwise, then pull it straight out of the lens assembly 86726p15.jpg
    To install:
  3. Wearing gloves or holding the replacement bulb with a cloth rag to keep oil off of the bulb surface, insert the bulb into the rear hole of the headlamp assembly. Make certain that the alignment grooves and tabs line up, push the light bulb into the assembly until seated flush, then turn the bulb clockwise 1?4 turn.
  4. Plug the electrical light bulb wiring harness into the new light bulb. Install any items removed from the engine compartment.
PREMIER AND MONACO Unlike the other vehicles covered by this manual, the removal and installation of the headlamp bulbs in the Premier and Monaco models requires the extraction of the entire headlamp lens assembly.
  1. Remove the grille-to-headlamp assembly attaching screws.
  2. Disconnect the headlamp aiming cable from the aiming screw end.
  3. Remove the headlamp assembly attaching bolts from above and behind the lamp assembly and separate the lamp assembly from the vehicle.
  4. Unplug the headlamp wire connector. NOTE: Do not touch the bulb with bare fingers or any possibly oily surface, since reduced bulb life may result!
  5. Rotate the socket counterclockwise 1?4 turn and pull the socket from the back of the lens assembly. Fig. 4: Remove the bezel retaining screws to loosen the headlamp assembly - Premier and Monaco 86726g91.gif
    Fig. 5: Detach the headlamp wire connector - Premier and Monaco 86726g92.gif
    Fig. 6: Once the headlamp assembly has been removed from the vehicle, the various light bulbs can easily be removed - Premier and Monaco 86726g93.gif
    To install:
  6. Wearing gloves or holding the replacement bulb with a cloth rag to keep oil off of the bulb surface, insert the bulb into the rear hole of the headlamp assembly. Make certain that the alignment grooves and tabs line up, push the light bulb into the assembly until seated flush, then turn the bulb clockwise 1?4 turn.
  7. Plug the headlamp wire connector back into the headlamp bulb.
  8. Install the assembly into the vehicle and secure in place with the mounting bolts.
  9. Connect the headlamp aiming cable to the aiming screw end.
  10. Install the grille-to-headlamp assembly attaching screws.

Lincoln town car 1995 radio won't turn off


I have seen people remove the factory radio, cut the harness and splice it to an aftermarket headunit, then attempt to reattach the factory harness they cut off to install the OEM radio back in proir to sale. Try removing the radio and look to see if the wires have been tampered with. If so you need to reconnect the harness wire by wire and use crimp connectors not the twist and tape method. Otherwise the electrical system has been altered elsewhere. The ACC lead to the radio should power off the radio when you turn off the ignition no matter what unless the electrical system has been modified.
