On my 1988 Camaro SC my sidemarker lights keep going out along with my passenger side front blinker. Bulbs are all new and work until you turn blinker on. Once this happens both sidemarker lights and passenger side blinker go out again. When I bought the car the headlights did not work properly. Low beam works but when switched to high beam passenger side low and high beam go out. I found a ground wire and attatched it to high beam on passenger side and now my headlights work with the exception of both lights on passenger side come on when high beams are on. I'm no good when it comes to wiring so any input would be greatly appreciated.

 

Ok now that I have good bulbs in place the passenger side front turn signal does not come on with headlights. Side marker on drivers side does not work either. All other lights work properly.
