    everything works fine. its just the lights that would usually turn on when the light nob is turned to the first position.

    oh yes and the front fogs dont work either. i assume this is because they will only turn on if the side lights are on.

    all fuses and relays are fine.

    i suspect it is a broken connection somewhere or a corroded ground point but i dont know where to look!

    thanks very much!

    thanks for you help.

    I have just removed the panel under the steering column. There are several wires coming out of the bottom of the indicater stalk. the grey and green wires are not attatched to anything - they stick out about 2 inches front the bottom of the stalk then dont connect to anything and are not terminated - just like they have been cut.

    does this sound like the cause of the problem?

    thanks again

    the problem has only just happened.

    I have found a wiring diagram for the lighting circuit but there is no mention of a green or grey wire coming from the stalk. I therefore assume these are supposed to be unattached. Is there any way I can send the jpg to you?

I would suspect the switch itself,or the wire from it ,as if it were a ground issue i do not expect it to effect the dash.You can usually check by the relay socket(on whatever lighting relay) on pin 1,whether you have 12v or not when you turn on the switch and a constant 12v on another,or fit a jumper lead from the constant 12v to the opposite side(4 pin relay)to test the circuit and operate the lights.

Hope this helps.

    Has this problem just happened, or have you bought the car with the problem?

    If the latter then this might well be the cause and I can come back to you,but I would need to find some schematics for your car to help you.

    Please get back to me .

No tail lights on a 99 jeep grand Cherokee

there are many running lamps. best name is park
some go front, some go tail, some go side, and some go
to dash. largest run of 1 circuit on car.... park.
then HL switch, 1 click, does dash glow.?
does all side lamps glow, and front and rear.?
check fuses first. as that is always first.
some jeeps have a relay called , PARK.
license plate rear lamp out too>????????????
fuse 6 in JB , junction fuse box is park
as is park relay
the BCM computer, sees you turn the park switch
the BCM the (the brain inside) energizes the PARK relay
and if the fuse is good , all parks glow.
including the lic, plate lamps.

what we do is check battery voltage first.
12.6vd is good, less is bad. i do this with parks on, and key on pocket as parks work all the time.
then check fuse 6
then last scan the PCM
if the PCM reports BCM errors, for park. we'd not IGNORE THAT.
did you?

What is behind the fuse box

You really need a good wiring diagram. Those cars are basically a toyota corolla on the inside with a good amount of mods to the electrical system. Grab a manual from an auto parts store or go to a local tech school that has an auto repair program and make copies. This will save you loads of time troubleshooting the problem. 25322389-21syibu3fgwpdxocjnkpw0ib-3-0.jpg

No tail lights

no (park -tail-running lights) is dash parking lamps glowing?
check the tail fuse yet?
94 accord
this circuit is huge, park/tail, up to 20 lamps. are all dead>?
front park, side park, tail park and dash lamps all out.
this i the red-blk feed. all comments , USA, as lighting varies by country. (laws)
license plate light dead too????????? that too is park
there is NO RELAY.
the fuse 32 feeds the HL (head light) switch and in PARK posistion
it feeds 12vdc raw power to all 38 lamps. (side corning lamps,etc)
the license plate lamp is key, there are 2 lamps.
and both probably are not out.
so if they are good lamps and both tail lamps are good and fuse
then they must glow, if one lamp shorts as 1156 or the like love to do
then it blows the fuse. as does the trailer jack (option) .

so fuse 32 park/tail blown
or HL park switch bad, if all 20 odd lamps dead. and fuse holds.
that simple, and this cars wiring is very simple and nice.

I need diagrams for the fuse boxes in the dash and engine compartment so I can find the fuse/relay I need to replace. My dash lights, tail lights and windsheild wipers are out.

There are a couple of wiring diagram and manual available on the net. The relay you are talking about is the park lamp relay which supplies power to the tail lamps, license plate lights and both front and rear park lamps. If the park and plate lights are working the light switch, relay and supply power are good. You need to verify for a broken brown wire to the tail lamps (assuming the sockets, lamps and grounds on both tail lights are good) .If none of the lamps are working then the 15A fuse number 3, the light switch or the park lamp relay could be bad (note different contact in the main light switch work the other lights)

You can find a wiring diagram and component location at and

Let us know if you want something more else accept the solution.
Thanks for contacting
