88 subaru wagon when headlights are on the parkers arent turn switch to parkers light up also drivers side headlight glows dim something is back feeding in wiring but havent found it yet tried another headlight switch checked battery ends grounds any clues thanks in pa

Sorry, but reading your post made my brain hurt. Try using periods to get more responces. Anyways, In my XT I had the same problem, you could hit the headlights and the parking lights were a no go, but hit the parking light switch and it was happy. My problem is that I have big feet, and I pulled a wire loose under the dash. Check there first, If I remmeber, there are two wires going into a connector right above where your feet would be. As far as a dimming on one headlight, check the connector at the light. Sometimes corrosion can get in there and gum up the works. Clean it up a little, of course it could be the bulb.

Good luck,

Welcome aboard the good ship USMB. Good to see another Pa-ian in the mix.

Strange problem you have workin here.

I'm gonna guess it's the right (pass. side) headlamp that is dim???

 

If so you may have a right side headlight relay

that is toast. (under the dash, up beside the streeing col. on the outboard side

- very hard to get to. There will be a cluster of relays may have to drop the ECU to have at it)

 

Just for kickies, try switching the parking light switch on top of

the steering column a couple times,

maybe it's stuck in an intermediate position.

 

Next the ground for both headlights is the black ground wire connection on

the inner fender behind the coil.

Pretty hard to see, may have to lift the coil bracket.

 

If you are new to Roo's the headlights work by switching the ground side of the

lamp filament you want lit -

not the hot side (like most American cars do).

 

Here is a wiring diagram.

Hope this helps.
