Hello, I own a 93 saab 9000 cs and i cant figure out whats wrong with my headlights. When the headlight switch is in the middle position (for parking lights) , the parking lights come on, but when the switch is moved to the headlight position, All lights on the car including dash lights go out. Ive read around and heard people say that this is caused by the red relay under the hood, so I got another one from a junk yard but it didnt solve the problem. Im not sure how I would go about sodering the relays if needed. This is a very annoying issue as i am going to have to travel alot at night for an upcoming job. Any advice or procedure for correcting this problem would be very much appreciated, thank you.
