hey guys ..this is my first post btw i need to find the overdrive relay on my 1993 940 non turbo. can somebody tell me where it is?

 

The relay is usually in the dash, sometimes on the side of the glove compartment. If it is still working, click it and see if you can follow the noise. Some are also near the steering post. I never saw one so I can't describe it to you. Good luck!
