For a while when I use my lights fuse #7 pops.
I have not put in an aftermarket radio. And I have not connected the blue and black wire in the back.
To solve this problem I have replaced the headlight switch for a new one, but this hasn't worked.
What else can I do before bringing it to a mechanic.

 

does it pop as soon as you pull to parking lights or only when you pull all the way ?

 

As soon as I pull the switch in first click. Parking lights then the fuse pops.

 

Do turn signals and brake light work ?

 

Both work. Instrument lightning not.

 

First thing would be to remove all lights and remove bulbs all at once see if theres any visable issues . While there all out turn light on again see if it still blows . if not replace one bulb at a time untill it pops thats where your issue lies .

 

Which lights use this fuse?
Parking, tail, instrumental panel.
Any other?
If I have all bulbs out and it still happens what can be the cause?

 

Im talking about taill lights and turn signals first is there a tow hitched oon the bback ?

 

You need to look at the wireing to all exteriior lights for contaact with metal . Is therre any body ddamage any where ?

 

There is a tow hitch, but I see no wires comming from.
What about the instrumental panel? If there's a shortage the fuse will pop out if all bulbs are removed.
There is no body damage at the car.

 

look real good around and under the hitch i belive wires come down from drivers side area to supply for trailer wireing .

i hadthis problem for a while after eliminating the trailer hitch harness thingy we tore apart the dash and looked at every light. we ended up finding that the cigarette lighter light was shorting on its own ground. somehow got crossed and worn trough. look for that kind of stuff. its not the most fun thing to work through.

 

First I will check the bulbs and the wiring from the hitch.
Will come back to you later.

 

Disconected hitch wiring, problem still excists.
Removed the bulbs, with no bulbs in the problem still excists.
What Should I do next?
