The instrument panel cluster,tail (driving) lamps,& license plate lite do not lite. fuses 9,14,20 are ok. what else could be bad or broke?


Check fuse's #19 ,# 6 #4 check grounds 105 & 107
G107 In the left rear of the engine block next to the knock sensor. G105 In the thermostat housing
The park, tail, marker and license lamps are turned on when the headlamp switch is placed in the PARK or ON position or anytime the headlights are requested. The PK LPS fuse in the IP fuse block supplies battery positive voltage to the park lamp relay and the headlamp switch. The body control module (BCM) provides a ground, or control circuit, to the park lamp relay coil circuit during ALC operation. When the park lamps are turned on during ALC, the BCM energizes the park lamp relay. The park lamps can also be supplied battery positive voltage directly from the headlamp switch. Current flow is to the park, tail, marker and license lamps. The front park and marker lamps are grounded at G100 and G101. The rear park, tail, marker and license lamps are grounded at G400 and G401. If the headlight switch is left in the ON position, the park, tail and marker lamps will remain on until turned off or the battery runs dead.
Check the headlamp switch !

Check for Power on your License Plate Light, more than likely you have lost GROUND

Turn Signals, Do the Front Work and the Back don't? If NONE then FLASHER FUSE

2007 tail light fuse location honda crv


I had this problem with my 2007 Honda CRV -- all the lights worked EXCEPT the tail/running lights and the license plate light. The other tail lights worked -- brake, reverse, indicators, and hazards. Front headlights also worked, but when the headlights went on the back tail lights did not (not to safe for driving at night!!)
The fuse was #15 in the interior fuse box (under the dash driver side) with the label "small exterior lights" ( also check fuse #19 labeled "small lights main"). The cause of my problem, I believe, is a bad or lose wire in my license plate light.

Sounds like either your wiring from the Light switch is bad or the Light switch itself is bad. Check with your Owners manual to see if the "Parking lights" have a separate fuse.

Your tail and License plate lights would light with either the Headlights or the "Parking" light selected at the switch as would the front parking lights. If all lights except the headlights are out, your problem is closer to the light switch than at the mounting points of each Parking light or License plate light.

This is one case where you will not know if a dead wire off of the switch is dead because of a bad switch or a bad wire. You would have to detach the harness at the switch, test the wire bundle or jump the switch with power to see how it distributes power through the Harness. It will take a lot of time to rule out the switch. It may be cheaper to replace the switch and then work from there.

2001 Monte Carlo SS 3.8 v6 Rear park lights are out as well as the dash lights, brake lights work headlights work front running and park lights work, all turn signal lights work. replaced headlight switch...


Park, Tail, Marker Lamps, and License
The park, tail and marker lamps, including the license lamps, turn on when the headlamp switch is placed in either the PARK or the HEAD position, or anytime the headlamps are requested. The RT I/P #1 fuse in the RH I/P fuse block supplies battery positive voltage to both the park lamp relay switch contacts and to the park lamp relay coil circuit. The park lamp relay coil is controlled by the body control module (BCM). When the headlamp switch is placed in the PARK position, the BCM energizes the park lamp relay coil control circuit.
Current flows from the park lamp relay switch to both front and rear park lamp fuses and to their respective park/tail lamps. The front park lamps are grounded at G101. The rear park lamps are grounded at G302. The license plate lamps are a part of the rear park lamp circuit and are grounded at G302. The inadvertent power control feature prevents the park lamps from remaining on more than 10 minutes if left on. If the park lamps are turned on after the ignition switch has been turned OFF, or is in the ACCY position, they will remain on until turned off or until the battery runs dead.

Did you the REAR PARK LP fuse 15 amp in the right insturment panel fuse box.
