Get workshop manual, follow tests in it.

Check the wiring around the boot/trunk hinge on the right hand side.


Where the hinge pivots it can break the wires.

 

+1 on the hinge wiring!

 

Thank you guys , you were exactly right ,, I took off the plastic hinge cover and found 5 broken wires !!

 

ok so i put the wires back together at the trunk hinge and that fixed a lot of things but im still missing front fog lights, rear running lights ( all other lights work including rear fog lights ) and lights in the stereo system and climate contols??? any thoughts?

 

fuses? Wiring errors? bad splices?

 

been thru all the fuses ,, nothing

 

the only splices are the ones in the trunk i just did and they are good

 

Well, then it is time to start the sometimes painful task of chasing everything down with the schematic and a test lamp or meter. I like a testlamp for circuit tracing because it applies some loasd and is easier to see while lying on you back upside down!

The stickys have the JTIS manual with the electrical drawings and several kind forum members have separated them out - I am sure they will jump in and forward them to you if you ask. Make sure you have ther drawing for your model year. There are some changes year to year.

Also, if yoiu need advice tracing the circuits along the way, say the word after you have the schematic and a test device in hand.

 

It is possible your latest problem is with a loose wire (or more) in the multifunction switch, controlled by light stalk on the left of the steering wheel.

Search for multifunction switch; removing steering wheel; clock spring, etc for instructions on removing wheel and examining the switch -- rats nest of wires that control the lights you are missing.

 

A note on the hinge wiring, check it all the way back through the insulation into the fuel tank compartment, that is where mine was broke at. I didn't notice it at first.
